SAFETY INFORMATION

For your safety and the safety of others, pay special attention to these precautions.

• Know how to stop the engine quickly in case of emergency. Understand the use of all controls.
• Do not exceed the boat manufacturer's power recommendation, and be sure the outboard motor is properly mounted.
• Never permit anyone to operate the outboard motor without proper instruction.
• Stop the engine immediately if anyone falls overboard.
• Do not run the motor while the boat is near anyone in the water.
• Attach the emergency stop switch lanyard securely to the operator.
• Before operating the outboard motor, familiarize yourself with all laws and regulations relating to boating and the use of outboard motors.
• Do not attempt to modify the outboard motor.
• Always wear a PERSONAL FLOTATION DEVICE (PFD) when on board.
• Exhaust contains poisonous carbon monoxide which can cause unconsciousness and may lead to death. Never run the outboard in a closed garage or confined area.
• Gasoline is extremely flammable and is explosive under certain conditions. Refuel in a well ventilated area with the engine stopped.
• Do not smoke or allow flames or sparks where the engine is refueled or where gasoline is stored.
• Do not overfill the fuel tank. After refueling make sure that the fuel tank cap is closed properly and securely.
• Be careful not to spill any fuel while refueling. Spilled fuel or fuel vapor may ignite. If any fuel is spilled make sure that the area is dry before starting the engine.
• Do not remove any guards, labels, shields, covers or safety devices; they are installed for your safety.

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

2.0 HP (1.5 kW)

WARNING

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

1. Installation position

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

2. Installation height

For proper propeller depth and engine cooling, the boat's transom height must match the motor's shaft length.

This outboard motor is intended for use with boats that have a transom height of:

380 mm (15.0 in)

Once the boat is in the water and loaded, check proper motor depth by looking at the anti-ventilation plate: with the motor not running, the plate should be below the surface of the water.

It should be about:

100 mm (3.9 in)

STERN CENTER

TRANSOM HEIGHT

Simple line drawing of a boat with a triangular handle and a rectangular block, no text or symbols present

During operation, check to be sure the anti-ventilation plate remains under water at all times and that water flows from the water check hole. Excessive or imbalanced loading will affect the motor's water depth. Loading too far forward will raise the motor out of the water, reducing engine cooling. Loading too much or too far rearward will push the motor deeper, reducing performance.

NOTICE

Insufficient water supply (anti-ventilation plate out of the water) may cause overheating that will damage the outboard motor.

3. Motor attachment

Attach the stern bracket to the transom and tighten the clamp screws.

CAUTION:

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

4. Motor angle (cruising)

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

GIVES MAXIMUM PERFORMANCE

5. Motor angle adjustment

If the propeller shaft is not parallel with the water surface, adjust by changing the transom angle adjusting bolt position.

There are four adjusting stages.

1. Loosen the wing nut to free the adjusting bolt.
2. Adjust the angle of the motor, and tighten the wing nut. Be sure that the bolt head and wing nut are seated in one of the four recesses on the adjustment slot.

NOTICE

To prevent damage to the motor or boat, make sure the transom angle adjusting bolt is locked.

1. Engine oil level

NOTICE

• Engine oil is a major factor affecting engine performance and sevice life. Nondetergent and low quality oils are not recommended, because they have inadequate lubricating properties.
• Running the engine with insufficient oil can cause serious engine damage.

Use Honda 4-stroke oil, or an equivalent high detergent, premium quality motor oil certified to meet or exceed U.S. automobile manufacturer's requirements for Service Classification SG, SF/CC, CD. Motor oils classified SG, SF/CC, CD will show this designation on the container.

SAE 10W/30 is recommended for general, all-temperature use. Other viscosities shown in the chart may be used when the average temperature in your area is within the indicated range.

1. Position the outboard motor vertically, and check the oil level in the oil level inspection window.
2. If the oil level is down toward the lower level mark on the window, fill up to the upper level mark on the dipstick.

2. Fuel level

Remove the filler cap and check the fuel level. Refill the tank if the fuel level is low.

Fuel tank capacity: 1.0 ℓ (0.26 US gal, 0.22 Imp gal)

WARNING:

Gasoline is extremely flammable, and gasoline vapor can explode, causing serious injury or death. Do not smoke or allow flames or sparks in your working area. KEEP OUT OF REACH OF CHILDREN.

NOTE:

Open the vent knob before removing the fuel filler cap. When the vent knob is firmly closed, the cap will be difficult to remove.

Recommended fuel

Your engine is designed to use any gasoline that has a pump octane number (R+M)/2 of 86 or higher, or that has a research octane number of 91 or higher. Gasoline pumps at service station normally display the pump octane number.

We recommend that you use unleaded fuel because it produces fewer engine and spark plug deposits and extends the life of exhaust system components.

Never use stale or contaminated gasoline or an oil/gasoline mixture. Avoid getting dirt, dust or water in the fuel tank. Use of a lower octane gasoline can cause persistent "pinging" or heavy "spark knock" (a metallic rapping noise) which, if severe, can lead to engine damage.

NOTICE

If "spark knock" or "pinging" occurs at a steady engine speed under normal load, change brands of gasoline. If spark knock or pinging persists, consult your authorized Honda dealer. Failure to do so is considered misuse, and damage caused by misuse is not covered by Honda's Limited Warranty.

Occasionally you may experience light spark knock while operating under heavy loads. This is no cause for concern, it simply means your engine is operating efficiently.

After refueling, be sure to tighten the fuel tank cap firmly.

GASOLINES CONTAINING ALCOHOL

If you decide to use a gasoline containing alcohol (gasohol), be sure it's octane rating is at least as high as that recommended by Honda. There are two types of "gasohol": one containing ethanol, and the other containing methanol. Do not use gasohol that contains more than 10% ethanol. Do not use gasoline containing methanol (methyl or wood alcohol) that does not also contain cosolvents and corrosion inhibitors for methanol. Never use gasoline containing more than 5% methanol, even if it has cosolvents and corrosion inhibitors.

NOTE:

- Fuel system damage or engine performance problems resulting from the use of fuels that contain alcohol is not covered under the warranty. Honda cannot endorse the use of fuels containing methanol since evidence of their suitability is as yet incomplete.

- Before buying fuel from an unfamiliar station, try to find out the fuel contains alcohol, if it does, confirm the type and percentage of alcohol used. If you notice any undesirable operating symptoms while using a gasoline that contains alcohol, or one that you think contains alcohol, switch to a gasoline that you know does not contain alcohol.

3. Pre-operation check list:

①Check the propeller, the shear pin, and the cotter pin to be sure they are secure and undamaged.
②Check the stern bracket to be sure the motor is securely installed.
③Check tiller handle operation.
④Check the condition of the fuel cap and fuel cap gasket.

Replace the fuel cap and fuel cap gasket if they are cracked or damaged.

⑤Make sure you have the tool kit and spare parts with you (P. 27).

⑥Check the anode metal for damage, looseness or excessive corrosion.

The anode metal helps to protect the outboard motor from corrosion damage; it must be exposed directly to the water whenever the motor is in use. Replace the anode metal when it has been reduced to approximately one half of its original size.

NOTICE

The possibility of corrosion damage increases if the anode metal is painted over or allowed to deteriorate.

The following materials should be kept with the boat:

1. Owner's Manual.
2. Tool Kit.
3. Spare engine oil, spark plugs, propeller and propeller cotter pins.
4. Required information regarding boating laws and regulations.

A WARNING

Exhaust contains poisonous carbon monoxide which can cause unconsciousness and may lead to death. Never run the outboard in a closed garage or confined area.

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. Open the fuel cap vent knob 2 to 3 turns.

1. Turn the fuel valve lever ON.

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

A 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.

NOTE:

• The engine will not start unless the emergency stop switch clip is engaged with the engine stop switch.
- A spare emergency stop switch clip is provided in the tool bag. EMERC

NOTICE

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

4.Tilting the 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 turn the fuel valve lever off.
2. Close the fuel cap vent knob.
3. With the motor in the forward position, raise the motor using the handle on the engine cover. The spring-loaded tilt lever will automatically move into position and hold the motor when it reaches approximately 75°.
4. Adjust the steering friction bolt to keep the motor from moving.

NOTICE

If the motor is tilted in the reverse position, crankcase oil will enter the cylinder and may cause difficult starting or may prevent the engine from being cranked. If this occurs refer to the TROUBLESHOOTING section (page 37).

1. To return the motor to the normal RUN position, hold the motor by the handle on the engine cover and pull the tilt lever toward you, then lower the motor slowly.

NOTICE

Do not use the tiller handle to tilt the outboard motor.

NOTICE

To avoid damaging the motor, use the utmost care when mooring a boat, especially when its motor is tilted up. Don't allow the motor to strike against the pier or other boats.

NOTICE

To avoid damaging the motor, never use it as a handle for lifting or moving the boat.

Trailering

When trailering or transporting the boat with the motor attached, it is recommended that the motor remain in normal running position with the steering friction bolt tightened securely.

NOTICE

Do not trailer or transport the boat with the motor in the tilted position. The boat or motor could be severely damaged if the motor drops.

The motor should be trailed in the normal running position. If there is insufficient road clearance in this position, then trailer the motor in the tilted position using a motor support device such as a transom saver bar, or remove the motor from the boat.

● High altitude operation

At high altitude, the standard carburetor air-fuel mixture will be excessively rich. Performance will decrease, and fuel consumption will increase.

High altitude performance can be improved by installing a smaller diameter main fuel jet in the carburetor and readjusting the pilot screw. If you always operate the outboard motor at altitudes higher than 6,000 feet above sea level, have your authorized Honda Outboard Motor dealer perform these carburetor modifications.

Even with suitable carburetor jetting, engine horsepower will decrease approximately 3.5% for each 1,000 foot increase in altitude. The effect of altitude on horsepower will be greater than this if no carburetor modification is made.

NOTICE

Operation of the outboard motor at an altitude lower than the carburetor is jetted for may result in reduced performance, overheating, and serious engine damage caused by an excessively lean air/fuel mixture.

• In an emergency

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

NOTE:

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

• In normal use

1. Move the throttle lever to the SLOW position.

1. Push the engine stop switch until the engine stops.

2. Remove the emergency stop switch lanyard and store it.

1. Turn the fuel valve lever OFF.

1. Close the fuel cap vent knob.

NOTICE

• Any other transport or storage position may cause damage or oil leakage.

1. Store the outboard motor in a clean, dry area.

NOTE:

Before storing, clean, flush, and lubricate the outboard motor as described on pages 31 and 32.

A 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.

1. Is the spark plug firing?

b. Install the spark plug in its cap, and ground the side electrode to any engine ground away from the spark plug hole.
c. Pull the recoil starter briskly, and see if the plug sparks.
d. If the spark plug is OK, reinstall it, and try to start the engine.
