The labels shown here contain important safety information. Please read them carefully. These labels are considered permanent parts of your outboard motor. If a label comes off or becomes hard to read, contact an authorized Honda servicing dealer for a replacement.

CONTROLS & FEATURES

COMPONENT & CONTROL LOCATIONS

CONTROLS

Engine Stop Switch

The engine stop switch has controls for normal engine stopping and emergency engine stopping.

In normal operation, press the engine stop button to stop the engine.

A clip and lanyard system stops the engine automatically if the operator falls away from the controls.

The switch clip must be inserted in the engine stop switch in order for the engine to start and run. The other end of the lanyard attaches to the operator's wrist. If the operator falls away from the controls, the lanyard pulls the clip out of the switch.

Always attach the lanyard to your wrist before operating the outboard motor.

A spare switch clip is supplied with the tool kit.

Choke Knob

The choke knob opens and closes the choke valve in the carburetor.

The CLOSED position enriches the fuel mixture for starting.

The OPEN position provides the correct fuel mixture for operation after starting, and for restarting a warm engine.

Throttle Grip

The throttle grip controls engine speed.

An index mark on the tiller arm indicates throttle position.

The BF9.9A gearshift mechanism limits throttle grip movement when the gearshift lever (p. 14) is in the N (neutral) position.

The BF15A gearshift mechanism limits throttle grip movement when the gearshift lever (p. 14) is in the R (reverse) or N (neutral) position.

Throttle Friction Knob

The throttle friction knob adjusts resistance to throttle grip rotation.

Turn the knob clockwise to increase friction for holding a throttle setting while cruising.

Turn the knob counterclockwise to decrease friction for easy throttle grip rotation.

Gearshift Lever

The gearshift lever is used to select F (forward), N (neutral), or R (reverse) gears.

The engine can be started with the gearshift lever in the N (neutral) position only.

If the gearshift lever is in the F (forward) or R (reverse) position, the recoil starter will not operate, and the electric starter button (applicable models) is blocked.

Recoil Starter Grip

Pull the starter grip to operate the recoil starter for starting the engine manually.

Electric Starter Button (models equipped with electric starter)

Press the starter button to start the motor.

Steering Friction Bolt

The steering friction bolt adjusts steering resistance.

Turn the bolt clockwise to increase friction for holding a steady course while cruising or to prevent the outboard motor from swinging while trailing the boat.

Turn the bolt counterclockwise to reduce steering friction.

Tilt Lever

The tilt lever enables the outboard motor to be raised for shallow water operation, beaching, launching, or mooring.

To tilt, move the lever to the TILT position, then raise the outboard motor until the tilt mechanism engages at 30°, 45° or 70° (p. 38).

To return the outboard motor to the normal running position, move the tilt lever to the RUN position, raise the outboard motor slightly to disengage the tilt mechanism, then slowly lower the engine.

Transom Angle Adjusting Rod

The transom angle adjusting rod is used to adjust the angle of the outboard motor in the normal operating position (see page 21).

To adjust, first tilt the outboard motor, so it is not resting on the rod.

Push the rod in, and turn the end of the rod up, so the latch will fall into line with the rod.

Remove the rod, and reinsert it in the desired position.

Push the rod in, and turn the end of the rod down, so the latch will fall to the locked position. Then release the rod.

Engine Cover Lock Lever

The engine cover lock lever fastens the cover to the outboard motor.

To remove the cover, move the lever to the unlocked position, then lift off the cover.

To install the cover, position the cover on the outboard motor, then move the lever to the locked position.

Fuel Priming Bulb

A priming bulb is built into the fuel hose that connects the portable fuel tank to the outboard motor.

Before operating the outboard motor, squeeze the priming bulb until it feels firm. This will ensure that fuel is supplied to the engine (see page 28).

Fuel Cap Vent Knob

The cap is provided with a vent knob to seal the portable fuel tank for carrying it to and from the boat. Open the vent knob 2 or 3 turns before operating the outboard motor (see page 28).

FEATURES

Fuel Gauge

A fuel gauge is built into the cap of the portable fuel tank (see page 44).

Oil Prssure Indicator Light

The oil pressure indicator light should remain lit while the engine is running. The light indicates that oil pressure is OK (see page 31).

Water Check Hole

Water should flow from the water check hole while the engine is running. This shows that water is circulating through the engine cooling system (see page 32).

Anode

The anode is a sacrificial material which helps to protect the outboard motor from corrosion.

Overrev Limiter

The engine is equipped with an overrev limiter to prevent the possibility of mechanical damage from excessive engine speed.

The overrev limiter may be activated during operation, limiting engine speed, if the outboard motor is tilted excessively, or when ventilation occurs during a sharp turn.

If the overrev limiter is activated, check the height and angle of the outboard motor.

NOTICE

Excessive tilt angle during operation can cause propeller ventilation, overheating, and water pump damage.

INSTALLATION

It is your responsibility to choose a boat suitable for the outboard motor.

WARNING

Do not exceed the boat manufacturer's power recommendation. Damage and injury may result.

INSTALLATION POSITION

Install at the stern, at the center line of the boat.

INSTALLATION HEIGHT

For proper propeller depth and engine cooling, the boat and outboard motor transom height must match.

Three outboard motor transom heights are available. Match your boat's transom height to the outboard motor transom height shown below.

Outboard Motor
Type	Transom Height
Short : S	17.3 in (440 mm)
Long : L	22.4 in (570 mm)
Extra Long : X	28.0 in (710 mm)

The anticavitation plate should be 0 - 2 in (0 - 50 mm) below the bottom of the boat. With the boat in the water, loaded and motor off, the anticavitation plate should be about 3.9 in (100 mm) below the surface of the water.

NOTICE

Running the outboard motor without sufficient cooling water will damage the water pump and overheat the engine.

OUTBOARD MOTOR ATTACHMENT

Attach the stern bracket to the trans- som and tighten the clamp screws.

NOTICE

• Before operating the boat, check the tightness of the clamp screws.
• Tie a rope through the hole in the stem bracket and secure the other end of the rope to the boat. This will prevent accidental loss of the motor.

To prevent the outboard motor from falling accidentally, you may further secure the stern bracket to the trans- som board with commercially avail- able bolts, nuts and washers.

After attaching the stern bracket to the transom board, be sure to apply sealant (THREEBOND 1216 or equivalent) to the bolt holes.

This modification should be made by your authorized Honda marine dealer.

MOTOR ANGLE FOR CRUISING

Adjust the motor so the propeller shaft is parallel with the water surface.

BATTERY CONNECTIONS

Honda BF9.9A and BF15A outboard motors produce a 12-volt, 6-ampere battery-chaging current and are equipped for connection to a 12-volt battery. The battery-charging circuit is protected by a 15-ampere fuse located in the engine compartment.

The outboard motor's 12-volt output is intended for battery charging only. Lights and electrical accessories for the boat should be connected to the battery.

Models With Electric Starter

These models are equipped with battery cables. The positive (+) cable has a red band at the battery connector. The negative (−) cable has a black band at the battery connector.

For electric starter operation, use a 12-volt battery with an ampere-hour rating of at least 40 Ah.

Models Without Electric Starter

These models are equipped with a 12-volt dc battery-charging receptacle and a plug which can be wired to a 12-volt battery to power lights and electrical accessories for the boat.

The receptacle is provided with a rubber cap, which should be attached when the plug is removed, in order to keep the receptacle clean and dry.

To prepare the outboard motor for connection to a battery, pull the plug out of its rubber boot, route suitable electrical wires through the boot, and screw them to the plug positive (+) and negative (−) terminals. Coat the plug terminals with grease, and reinstall the plug in the rubber boot.

Battery Installation

Place the battery in a corrosion-resistant battery box that is securely mounted in a location away from the fuel tank and protected from water and direct sunlight.

WARNING

The battery contains sulfuric acid (electrolyte), which is highly corrosive and poisonous.

Getting electrolyte in your eyes or on your skin can cause serious burns.

Wear protective clothing and eye protection when working near the battery.

EMERGENCY PROCEDURES

Eyes — Flush with water from a cup or other container for at least 15 minutes (water under pressure can damage the eye). Immediately call a physician, local poison control center, or 911.

Skin — Remove contaminated clothing. Flush the skin with large quantities of water. Call a physician immediately.

Swallowing — Drink water or milk. Call your local poison control center or a physician immediately.

Connections to the Battery

Connect the positive (+) battery cable to the positive (+) battery terminal, then connect the negative (−) battery cable to the negative (−) battery terminal.

The negative (−) battery cable should always be removed from the battery when connecting or disconnecting the positive (+) battery cable, so tools cannot cause a short circuit if they touch a grounded part while being used on the positive (+) battery terminal fitting.

NOTICE

Be careful to avoid connecting the battery in reverse polarity, as that will damage the battery-charging system in the outboard motor.

OPERATION

SAFE OPERATING PRECAUTIONS

To safely realize the full potential of this outboard motor, you need a complete understanding of its operation and a certain amount of practice with its controls.

Before operating the outboard motor for the first time, please review the IMPORTANT SAFETY INFORMATION on page 7 and the chapter titled BEFORE OPERATION.

For your safety, avoid starting or operating the engine in an enclosed area. Your engine's exhaust contains poisonous carbon monoxide gas which can collect rapidly in an enclosed area and cause illness or death.

BREAK-IN PROCEDURE

Proper break-in procedure allows the moving parts to wear in smoothly for best performance and long service life.

For the first 10 hours, run the outboard motor at low speed, and avoid full-throttle operation.

PORTABLE FUEL TANK PLACEMENT AND CONNECTIONS

Fuel Tank Placement

Place the portable fuel tank in a well-ventilated location, away from direct sunlight.

WARNING

Gasoline is highly flammable and explosive.

You can be burned or seriously injured when handling fuel.

• Stop the engine and keep heat, sparks, and flame away.
• Handle fuel only outdoors.
• Wipe up spills immediately.

Line drawing of a Honda electric vehicle charging station with attached cable (no text or symbols)

To ensure that the outboard motor will be able to draw fuel from the tank, place the tank within 6 feet of the outboard motor and not more than 3 feet below the fuel connector on the outboard motor.

Secure the portable fuel tank in the boat, so it won't move around and become damaged.

Before use, open the fuel tank vent by turning the vent knob at least 2 or 3 turns counterclockwise.

Fuel Hose Connections

Connect the fuel hose to the tank and the outboard motor, as shown. Be sure both connectors snap securely into place.

Fuel Priming

FUEL HOSE CONNECTOR FOR FUEL TANK

STARTING THE ENGINE

1. Put the emergency engine stop switch clip in the engine stop switch, and attach the lanyard to your wrist.

The engine will not start or run, unless the clip is in the switch.

The emergency engine stop switch clip and lanyard system is a safety device that will stop the engine if you fall away from the controls while operating the boat.

Always attach the lanyard to your wrist before starting the engine.

1. Check the position of the gear-shift lever. It must be in the N (neutral) position for starting.

If the gearshift lever is in the F (forward) or R (reverse) position, the recoil starter will not operate, and the electric starter button (applicable models) is blocked.

1. Align the throttle grip START position with the mark on the tiller handle.

1. To start a cold engine, pull out the choke knob. To restart a warm engine, leave the choke knob pushed in.

1. Operate the starter.

USING THE RECOIL STARTER

Pull the recoil starter grip slowly until you feel resistance, then pull briskly.

NOTICE

• Do not allow the starter grip to snap back against the engine. Return it gently to prevent damage to the starter.
• Do not pull the starter grip while the engine is running, as that may damage the starter.

USING THE ELECTRIC STARTER (applicable models)

Press the starter button to operate the electric starter.

NOTICE

• Do not use the starter motor for more than 5 seconds. If the engine fails to start, release the starter button, and wait at least 10 seconds before operating the starter motor again.
• Do not press the electric starter button while the engine is running. This may damage the starter.
• After starting, check the oil pressure indicator light. The light should be on while the engine is running. If the light is off, stop the engine immediately, check the engine oil level, and inspect the engine for oil leaks.

If the engine fails to start, check the emergency stop switch clip.

If the oil level is OK, but the light stays off while the engine is running, take the motor to an authorized Honda marine dealer immediately.

1. After starting, be sure water is flowing out of the water check hole.

NOTICE

If water does not flow out, or if steam comes out, stop the engine. check to see if the screen in the cooling water inlet is obstructed. Do not operate the engine until the problem has been corrected.

1. If the choke was used, push it in gradually as the engine warms up.

2. Before leaving the dock, check the operation of the emergency stop switch.

EMERGENCY STARTING

If the recoil starter is not working properly, the engine can be started with the spare starter rope in the tool kit.

1. Remove the engine cover.

2. Remove the recoil starter by removing the three 6 mm bolts.

3. Disconnect the neutral starter cable.

4. Follow steps 1 through 4 of the normal engine starting procedure (p. 29 & 30).

5. Wind the spare rope clockwise around the pulley, and then pull it straight out to start the engine.

Keep clear of moving parts.

1. Leave the recoil starter off and reinstall engine cover.

WARNING

Exposed moving parts can cause injury. Use extreme care when installing the engine cover. Do not operate the outboard motor without the engine cover.

STOPPING THE ENGINE

Emergency Engine Stopping

Disengage the emergency engine stop switch clip from the engine stop switch by pulling the lanyard.

It is a good idea to stop the engine with the emergency engine stop switch lanyard from time to time to be sure that the switch is operating properly.

Normal Engine Stopping

1. Turn the throttle grip to the SLOW position, and move the gearshift lever to the N (neutral) position.

1. Push the engine stop switch button until the engine stops.
2. Remove the emergency engine stop switch lanyard and store it.

In the event that the engine does not stop when you push the engine stop switch, pull the emergency engine stop switch lanyard. If the engine continues to run, pull the choke knob to stop the engine.

GEAR SHIFTING

Put the tilt lever in the RUN position to prevent the outboard motor from tilting up when operating in reverse (refer to page 38).

The gearshift lever has 3 positions: FORWARD, NEUTRAL, and REVERSE. An indicator at the base of the gearshift lever aligns with letters F, N, or R on the engine case to show the gear that has been selected.

Turn the throttle grip to SLOW to decrease engine speed before moving the gearshift lever.

NOTICE

When operating in reverse, proceed with caution to avoid hitting any underwater obstructions with the propeller.

The BF9.9A gear shift mechanism limits throttle opening in the N (neutral) position. The BF15A gear shift mechanism limits throttle opening in the N (neutral) and R (reverse) positions. Both outboard motors allow the throttle to be opened to FAST with the gear shift lever in the F (forward) position.

STEERING

To turn to the right, swing the tiller handle to the left. To turn to the left, swing the tiller handle to the right.

Boats equipped with a remote control steering wheel are controlled in the same way as a car.

The steering friction should be adjusted so that stable boat operation is maintained with a minimum of operator effort.

CRUISING

With the gearshift lever in the forward position F, turn the throttle grip toward FAST to increase speed. For normal cruising, open the throttle about 3/4.

To hold the throttle at a steady setting, turn the throttle friction knob clockwise. To free the throttle grip for manual speed control, turn the friction knob counterclockwise.

This outboard motor is provided with an overrev limiter in order to prevent a breakdown due to excessive engine speed. If for example, the outboard motor is tilted excessively, or ventilation occurs during a sharp turn, the engine may overrev, activating the overrev limiter, causing engine speed to become unstable. If the engine speed becomes unstable when the outboard motor is run with the grip near the "fully open" position, return the grip to the "low speed" side until the speed becomes stable.

For best performance, passengers and equipment should be distributed evenly to balance the boat.

TILTING THE OUTBOARD MOTOR

Tilt the motor to prevent the propeller and gear case from hitting bottom when the boat is beached or stopped in shallow water.

1. Stop the engine and put the gearshift lever into NEUTRAL.
2. Pull the tilt lever toward you, set the lever in the TILT position, and raise the engine to either the 30^ , 45^ or 70^ tilt position.

NOTICE

Do not use the throttle grip to tilt the outboard motor.

HELPFUL TIPS & SUGGESTIONS

STORING YOUR OUTBOARD MOTOR

Storage Preparation

Proper storage preparation is essential for keeping your pump troublefree and looking good. The following steps will help to keep rust and corrosion from impairing your outboard motor's function and appearance, and will make the engine easier to start when you use the outboard motor again.

Cleaning and Flushing

Wash the outside of the outboard motor with clean, fresh water, and flush the cooling system as described on page 46.

Disengage the emergency engine stop switch clip from the engine stop switch, and pull the recoil starter rope several times to expel any water remaining in the water pump.

Touch up any damaged paint, and coat areas that may rust with a light film of oil. Lubricate controls with a silicone spray lubricant.

Fuel

Gasoline will oxidize and deteriorate in storage. Old gasoline will cause hard starting, and it leaves gum deposits that clog the fuel system. If the gasoline in your fuel tank and carburetor deteriorates during storage, you may need to have the carburetor and other fuel system component serviced or replaced.

The length of time that gasoline can be left in your fuel tank and carburetor without causing functional problems will vary with such factors as gasoline blend, your storage temperatures, and whether the fuel tank is partially or completely filled. The air in a partially filled fuel tank promotes fuel deterioration. Very warm storage/temperatures accelerate fuel deterioration. Fuel deterioration problems may occur within a few months, or even less if the gasoline was not fresh when you filled the fuel tank.

The Distributor's Limited Warranty does not cover fuel system damage or engine performance problems resulting from neglected storage preparation.

1. Disconnect the fuel hose from the outboard motor.

2. With the outboard motor in a vertical position, place an approved gasoline container below the fuel drain outlet, and use a funnel to avoid spilling fuel. Loosen the drain screw to drain fuel from the carburetor.

WARNING

Gasoline is highly flammable and explosive.

You can be burned or seriously injured when handling fuel.

• Keep heat, sparks, and flame away.
• Handle fuel only outdoors.
• Wipe up spills immediately.

1. After the fuel has drained from the carburetor, tighten the drain screw securely.
2. Drain the fuel tank into an approved gasoline container, or if you need to store fuel in the portable fuel tank, you can extend fuel storage life by filling the fuel tank with fresh gasoline and adding a fuel stabilizer that is formulated for that purpose. Firmly close the fuel cap vent knob.

Engine Oil

1. Change the engine oil (see page 48).
2. Remove the spark plugs (see page 52)
3. Pour a tablespoon (5 - 10 cc) of clean engine oil into each cylinder.
4. Pull the starter rope several times to distribute the oil in the cylinders.
5. Reinstall the spark plugs.

Storage Precautions

Select a well-ventilated storage area. If possible, avoid storage areas with high humidity.

If your portable fuel tank contains gasoline, store it away from any appliance that operates with a flame, such as a furnace, water heater, or clothes dryer. Also avoid any area with a spark-producing electric motor, or where power tools are operated.

Store the outboard motor either vertically, or horizontally with the tiller handle side down, as shown.

If storing horizontally, be sure to fold the tiller handle, so the outboard motor rests on it's case protectors. Be sure all water has drained from the outboard motor before placing it on its side, so no residual water can enter the engine exhaust port.

NOTICE

Any other storage position may cause damage or oil leakage.

Technical line drawing of a mechanical assembly with no visible text or symbols

CASE PROTECTORS

Cover the outboard motor to keep out dust. Do not use sheet plastic as a dust cover. A nonporous cover will trap moisture, promoting rust and corrosion.

Removal From Storage

Check your outboard motor as described in the BEFORE OPERATION chapter of this manual.

If the cylinder was coated with oil during storage preparation, the engine may smoke briefly at startup. This is normal.

TRANSPORTING

When trailering a boat with the outboard motor attached, leave the engine in the normal running position, if possible, and tighten the steering friction bolt securely (p. 36).

If there is insufficient road clearance in the normal running position, then tilt the outboard motor, leave the tilt lever in the tilt position, and use a motor support device, such as a transom-saver bar, or remove the outboard motor from the boat.

To transport the outboard motor when removed from the boat, secure it in either the vertical or horizontal position shown on page 59

To carry, hold the outboard motor by the carrying handle, or hold by the carrying handle and the lug beneath engine cover lock lever as shown below.

NOTICE

Lifting the outboard motor by the engine cover, or using the installed outboard motor as a handle or lever to move the boat, can damage the outboard motor.

TAKING CARE OF UNEXPECTED PROBLEMS

ENGINE WILL NOT START

1. Is the emergency stop switch clip in place?
2. Is the gearshift lever in neutral?
3. Is there fuel in the fuel tank?
4. Is the fuel tank vent knob turned to open?

5. Is fuel reaching the carburetor?

6. Is the fuel system primed by squeezing the primer bulb?

Loosen the carburetor drain screw to see if there is fuel in the carburetor float bowl.

WARNING

If any fuel is spilled, make sure the area is dry before testing the spark plug or starting the engine. Spilled fuel or fuel vapor may ignite.

TAKING CARE OF UNEXPECTED PROBLEMS

1. Are the spark plugs firing?

a. Remove and inspect the spark plugs. clean and dry the plugs, and check the electrode gaps (p. 52).

b. Install the spark plugs in their caps, and ground the side electrode to any engine ground away from the spark plug holes.

c. With recoil starter

Put the gearshift lever in the "NEUTRAL" position, pull the starter grip hard, and check to see whether or not a spark appears across the gap of the spark plug.

With electric starter (applicable models)

Put the gear lever in the "NEUTRAL" position, operate the starter motor, and check whether or not a spark appears across the gap of the spark plug.

If the spark plugs are OK, reinstall them, and try to start the engine.

If a spark does not appear, either replace the spark plugs or contact your authorized Honda marine motor dealer.

ENGINE OVERHEATS

1. Is the water intake screen clogged?
2. Is the thermostat faulty?
3. Is the water level correct?

BATTERY DOES NOT CHARGE AND ELECTRIC STARTER (applicable models) DOES NOT OPERATE

The battery-charging circuit (all models) and the electric starter relay circuit (applicable models) are protected by a 15-ampere fuse.

If the fuse burns out, running the engine will not charge the battery (all models), and the electric starter (applicable models) will not operate.

Fuse Replacement

1. With the engine stopped, remove the engine cover.
2. Remove the fuse holder from the fuse bracket. Pull the rubber cover off the end of the fuse holder, and unscrew the fuse holder cap.
3. Remove and inspect the fuse. If the fuse is burnt out, Install a replacement 15 A fuse. The outboard motor is supplied with a spare 15 A fuse, which is located below the fuse holder.

NOTICE

Never use a fuse with a rating greater than 15 amperes. Serious damage to the electrical system could result.

1. Reinstall the fuse holder and engine cover.

Before further operation, try to determine and correct the electrical problem that caused the fuse to burn out. An uncorrected electrical problem may cause the fuse to burn out again.

SUBMERGED MOTOR

A submerged motor must be serviced immediately after it is recovered from the water in order to minimize corrosion.

If there is a Honda marine dealership nearby, take the motor immediately to the dealer. If you are far from a dealership, proceed as follows:

1. Remove the engine cover, and rinse the motor with fresh water to remove salt water, sand, mud, etc.

2. Loosen the carburetor drain screw (p. 58), drain the contents of the carburetor into a suitable container, then tighten the drain screw.

3. Change the engine oil (p. 48). If there was water in the engine crankcase, or the used engine oil showed signs of water contamination, then a second engine oil change should be performed after running the engine for 1/2 hour.

4. Remove the spark plugs. Disengage the emergency engine stop switch clip from the engine stop switch and pull the recoil starter several times to completely expel water from the cylinders.

Carburetor Modification for High Altitude Operation

At high altitude, the standard carburetor air-fuel mixture will be too rich. Performance will decrease, and fuel consumption will increase. A very rich mixture will also foul the spark plug and cause hard starting.

High altitude performance can be improved by specific modifications to the carburetor. If you always operate your engine at altitudes above 5,000 feet (1,500 meters), have an authorized Honda marine dealer perform this carburetor modification.

Even with carburetor modification, engine horsepower will decrease about 3.5% for each 1,000-foot (300-meter) increase in altitude. The effect of altitude on horsepower will be greater than this if no carburetor modification is made.

NOTICE

When the carburetor has been modified for high altitude operation, the air-fuel mixture will be too lean for low altitude use. Operation at altitudes below 5,000 feet (1,500 meters) with a modified carburetor may cause the engine to overheat and result in serious engine damage. For use at low altitudes, have an authorized Honda marine dealer return the carburetor to original factory specifications.

TECHNICAL & CONSUMER INFORMATION

Oxygenated Fuels

Some conventional gasolines are being blended with alcohol or an ether compound. These gasolines are collectively referred to as oxygenated fuels. To meet clean air standards, some areas of the United States and Canada use oxygenated fuels to help reduce emissions.

If you use an oxygenated fuel, be sure it is unleaded and meets the minimum octane rating requirement.

Before using an oxygenated fuel, try to confirm the fuel's contents. Some states/provinces require this information to be posted on the pump.

The following are the EPA-approved percentages of oxygenates:

ETHANOL

(ethyl or grain alcohol) 10% by volume

You may use gasoline containing up to 10% ethanol by volume. Gasoline containing ethanol may be marketed under the name "Gasohol".

MTBE

(Methyl Tertiary Butyl Ether) 15% by volume

You may use gasoline containing up to 15% MTBE by volume.

METHANOL

(methyl or wood alcohol) 5% by volume

You may use gasoline containing up to 5% methanol by volume, as long as it also contains cosolvents and corrosion inhibitors to protect the fuel system. Gasoline containing more than 5% methanol by volume may cause starting and/or performance problems. It may also damage metal, rubber, and plastic parts of your fuel system.

If you notice any undesirable operating symptoms, try another service station, or switch to another brand of gasoline.

Fuel system damage or performance problems resulting from the use of an oxygenated fuel containing more than the percentages of oxygenates mentioned above are not covered under warranty.

Emission Control System Information

Source of Emissions

The combustion process produces carbon monoxide, oxides of nitrogen, and hydrocarbons. Control of hydrocarbons and oxides of nitrogen is very important because, under certain conditions, they react to form photochemical smog when subjected to sunlight. Carbon monoxide does not react in the same way, but it is toxic.

Honda utilizes lean carburetor settings and other systems to reduce the emissions of oxides of nitrogen, and hydrocarbons.

The U.S. Clean Air Act

EPA regulations require all manufacturers to furnish written instructions describing the operation and maintenance of emission control systems.

The following instructions and procedures must be followed in order to keep the emissions from your Honda engine within the emission standards.

Tampering and Altering

Tampering with or altering the emission control system may increase emissions beyond the legal limit. Among those acts that constitute tampering are:

• Removal or alteration of any part of the intake, fuel, or exhaust systems.
• Altering or defeating the governor linkage or speed-adjusting mechanism to cause the engine to operate outside its design parameters.

Problems That May Affect Emissions

If you are aware of any of the following symptoms, have your engine inspected and repaired by your servicing dealer.

• Hard starting or stalling after starting.

- Rough idle.

- Misfiring or backfiring under load.

• Afterburning (backfiring).

- Black exhaust smoke or high fuel consumption.

Replacement Parts

The emission control systems on your Honda engine were designed, built, and certified to conform with EPA emission regulations. We recommend the use of genuine Honda parts whenever you have maintenance done. These original-design replacement parts are manufactured to the same standards as the original parts, so you can be confident of their performance. The use of replacement parts that are not of the original design and quality may impair the effectiveness of your emission control system.

A manufacturer of an aftermarket part assumes the responsibility that the part will not adversely affect emission performance. The manufacturer or rebuilder of the part must certify that use of the part will not result in a failure of the engine to comply with emission regulations.

Maintenance

Follow the maintenance schedule on page 26. Remember that this schedule is based on the assumption that your machine will be used for its designed purpose. Sustained high-load or high-temperature operation, will require more frequent service.

Adjust the steering friction bolt so that a slight amount of drag is felt. The steering should move smoothly and freely.

Remote control friction adjustment

Operate the remote control lever into forward and reverse gears and check for the amount of drag felt.

Adjust the remote control friction adjuster so that a slight amount of drag is felt. The remote control lever should move smoothly and freely.

In addition to the above items review the pre-operation check list shown in the BF9.9A/15A owner's manual page 14.

Controls

Remote control lever

The remote control lever controls gear selection and throttle opening positions. It is necessary to pull up the neutral release lever to operate the remote control lever.

F (forward):

Moving the lever to the F position (approximately 30° from the N position) will engage the forward gear. Moving the lever farther from the F position will increase the throttle opening and the boat forward speed.

N (neutral):

The engine idles and the transmission gears are disengaged.

R (reverse):

Moving the lever to the R position (approximately 30° from the N position) will engage the reverse gear. Moving the lever farther from the R position will increase the throttle opening and the boat reverse speed.

5. STARTING THE ENGINE

Neutral release lever

The neutral release lever is on the remote control lever to prevent an accidental gear engagement.

The remote control lever will not engage forward or reverse gear unless the neutral release lever is pulled up.

Ignition switch

The remote control box is equipped with a key type ignition switch.

Key positions:

START

To activate the starter motor and start the engine. The remote control lever must be in the neutral position.

ON

To run the engine after starting.

The battery will discharge if the key is left in this position with the engine not running.

OFF

To stop the engine (IGNITION OFF).

Emergency stop switch lanyard

The emergency stop switch lanyard is provided to stop the engine immediately in the event the operator should fall overboard or away from the controls.

The emergency stop switch clip must be engaged with the emergency engine stop switch or the engine will not start. When the emergency stop switch clip becomes disengaged from the emergency engine stop switch the engine will stop immediately.

The emergency engine stop switch should not be used to normally stop the engine. Use the ignition switch to normally stop the engine.

Attach the emergency stop switch lanyard securely to the operator when operating the outboard motor.

A spare emergency stop switch clip is provided on the remote control box.

Choke/Fast idle lever

The choke/fast idle lever provides two functions:

1. Electric choke solenoid activation for easy engine start up.
2. Engine fast idle.

The choke/fast idle lever will not move unless the remote control lever is in the N (neutral) position. Conversely, the remote control lever will not move unless the choke/fast idle lever in the lowest position.

Lift and hold the choke/fast idle lever up fully, this will provide a rich fuel mixture and the correct fast idle. Do not run the engine while holding the lever in the choke position.

Gradually lower the choke/fast idle lever to the lowest position to decrease the choke and fast idle.

Manual choke knob

A manual choke knob is provided on the left side of the motor which can be used in the event the battery is discharged. When recoil starting, pull the choke knob and a rich fuel mixture will be provided to the engine. After the engine starts, be sure to push in the choke knob.

Oil pressure indicator light

The green oil pressure indicator light turns OFF when the oil level is low and/or the engine lubrication system is faulty.

Fuel line connection

Refer to the BF9.9A/15A owner's manual page 15.

Electric starting (ignition key)

NOTICE

The anti-ventilation plate must be lowered into the water and be at least 2 inches below the surface. Running the outboard motor out of the water will damage the water pump and overheat the engine.

1. Engage the emergency stop switch clip located at one end of the emergency stop switch lanyard with the emergency engine stop switch 1. Attach the other end of the emergency engine stop switch lanyard securely to the operator.

The engine will not start unless the emergency stop switch clip is engaged with the emergency engine stop switch.

WARNING

If the operator does not attach the emergency stop switch lanyard, and is thrown from his seat or out of the boat, the out-of-control boat can seriously injure the operator, passengers, or bystanders. Always properly attach the lanyard before starting the motor.

A spare emergency stop switch clip is provided on the remote control box.

1. Move the control lever to the N (neutral) position.

The engine will not start unless the control lever is in the N (neutral) position.

1. When the engine is cold and/or the ambient temperature is low, lift and hold the choke/fast idle lever up fully. This will provide a rich fuel mixture and the correct fast idle.

When the engine is warm, it may be necessary to raise the choke/fast idle lever slightly. Hold it in this position.

The choke/fast idle lever will not move unless the control lever is in the N (neutral) position.

1. While holding the choke/fast idle lever in the up position, turn the ignition key to the START position and release the key when the engine starts. The starter motor consumes a large amount of current. Do not run it continuously for more than 5 seconds at a time. If the engine does not start within 5 seconds wait at least 10 seconds before using the starter motor again.

NOTICE

Do not turn the ignition key to the start position while the engine is running. This can damage the starter motor and flywheel.

5. STARTING THE ENGINE

1. After starting the engine, return the lever slowly to the position where the engine does not stall. Hold the lever in position.

The control lever will not move unless the choke/fast idle lever is returned to the lowest position.

1. After the engine starts, verify water is flowing through the water check hole. The amount of water coming out of the water check hole will vary due to thermostat operation. Stop the engine if water does not come out the water check hole or if you see steam. Check the water intake screens and the water check hole port and if necessary remove any obstructions. If the problem continues, contact your closest authorized Honda Marine or Honda Outboard Motor dealer.

NOTICE

Running the outboard motor with an obstruction in the cooling system can damage the water pump and overheat the engine.

1. With the engine running, check to see if the green engine oil pressure indicator light turns ON.

Stop the engine if the oil pressure indicator light does not turn ON. Check the engine oil level. If the oil level is normal and the oil pressure indicator light does not turn ON, contact your closest authorized Honda Marine or Honda Outboard Motor dealer.

Recoil starting

If the electric starting system will not start the engine. The engine can be started using the recoil starter.

1. Move the control lever to the N (neutral) position.

1. Turn the ignition key to the ON position. Engage the emergency stop switch clip, located at one end of the emergency stop switch lanyard, with emergency engine stop switch 1.

1. Engage an emergency stop switch clip with emergency engine stop switch 2.

1. If the engine is cold and/or the ambient temperature is low, pull and hold the manual choke knob out. The choke knob is located on the front of the outboard motor.

If the fuel system is working properly, it should only be necessary to pull the recoil starter 1 or 2 times with the choke knob out.

1. Lift the choke/fast idle lever. The choke/fast idle lever will stay up in the fast idle position.

1. Pull the recoil starter rope slowly until resistance is felt, then pull briskly.

2. If it was necessary to use the manual choke knob to start the engine, slowly return it to its initial position.

3. Slowly return the choke/fast idle lever to the lowest position to where the engine does not stall.

1. After the engine starts, monitor the water discharge and the oil pressure indicator light.

5. STARTING THE ENGINE

Electric starting (starter button)
