OUTBOARD MOTOR SAFETY

IMPORTANT SAFETY INFORMATION

The Honda BF40D/BF50D outboard motors are designed for use with boats that have a suitable manufacturer's power recommendation. Other uses can result in injury to the operator or damage to the outboard motor and other property.

Most injuries or property damage can be prevented if you follow all instructions in this manual and on the outboard motor. The most common hazards are discussed in this chapter, along with the best way to protect yourself and others.

Operator Responsibility

  • It is the operator's responsibility to provide the necessary safeguards to protect people and property. Know how to stop the engine quickly in case of emergency. Understand the use of all controls.
  • Stop the engine immediately if anyone falls overboard, and do not run the engine while the boat is near anyone in the water.
    • Always stop the engine if you must leave the controls for any reason.

  • Attach the emergency stop switch lanyard securely to the operator.
    • Always wear a PFD (Personal Flotation Device) while on the boat.

  • Familiarize yourself with all laws and regulations relating to boating and the use of outboard motors.
  • Be sure that anyone who operates the outboard motor receives proper instruction.
  • Be sure the outboard motor is properly mounted on the boat.
  • Do not remove the engine cover while the engine is running.

OUTBOARD MOTOR SAFETY

Refuel With Care

  • Gasoline is extremely flammable, and gasoline vapor can explode. Refuel outdoors, in a well-ventilated area, with the engine stopped. Never smoke near gasoline, and keep other flames and sparks away.
  • Refuel carefully to avoid spilling fuel. Avoid overfilling the fuel tank.
    • After refueling, tighten the filler cap securely. If any fuel is spilled, make sure the area is dry before starting the engine.

Carbon Monoxide Hazard

Exhaust contains poisonous carbon monoxide, a colorless, odorless gas. Breathing carbon monoxide can cause loss of consciousness and may lead to death.

If you run the engine in an area that is confined, or even partly enclosed, the air you breathe could contain a dangerous amount of exhaust gas.

Never run your outboard inside a garage or other enclosure.

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, do not start or run the engine in a confined or partly enclosed area. Your engine's exhaust contains poisonous carbon monoxide, a colorless, odorless gas that can collect rapidly. Breathing carbon monoxide can cause loss of consciousness and may lead to death.

BREAK-IN PROCEDURE

Break-in period: 10 hours

Proper break-in operation allows the moving parts to wear in smoothly for best performance and long service life. Avoid continuous operation at a steady speed.

First 15 minutes:

Run the engine at trolling speed. Use the minimum throttle opening necessary to operate the boat at a safe trolling speed.

Next 45 minutes:

Run the engine up to a maximum of 2,000 to 3,000 rpm, which is about 10% to 30% of maximum throttle opening. Operating at maximum 2,000 \~ 3,000 rpm should be limited to 50% of the 45 minutes.

Next 60 minutes:

Run the engine up to a maximum of 4,000 to 5,000 rpm, which is about 50% to 80% of maximum throttle opening. Operating at maximum 4,000 \~ 5,000 rpm should be limited to 50% of the 60 minutes. 30-second full-throttle bursts are OK, but do not operate the engine continuously at full throttle.

For boats that plane easily, bring the boat up on plane, and then reduce the throttle opening to the recommended rpm range.

Next 8 hours:

Do not run the engine at full throttle for more than 5 minutes at a time.

OPERATION

TRANSOM ANGLE ADJUSTMENT (LH Type)
STERN BRACKET TURN UP PUSH TRANSOM ANGLE ADJUSTING ROD

OPERATION

CRUISING

Engine Speed

For best fuel economy, limit the throttle opening to 80%. Use the throttle friction control (p. 57, 58) to help you hold a steady speed.

For rough water conditions or large waves, slow down to prevent the propeller from rising out of the water.

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

If, for example, the outboard motor is tilted excessively or propeller ventilation occurs during a sharp turn, the engine may overrev, activating the overrev limiter.

If engine speed becomes unstable at high speed due to activation of the overrev limiter, reduce speed and check the trim angle of the outboard motor.

Trim

LH Type

Install the outboard motor at the best trim angle for stable cruising and maximum power.

Trim angle too large: Causes boat to "squat."

Trim angle too small: Causes boat to "bow steer."

It is necessary to trim the angle of the outboard motor to compensate for changes in boat load, weight distribution, water conditions, or propeller selection.

Under normal conditions, the boat will perform best when the

antiventilation plate is level with the water surface.

When cruising into a high wind, trim the outboard motor down slightly to level the boat and improve stability. With a tail wind, trim the outboard motor up slightly.

LHT, LRT and XRT Types

Use the power trim/tilt switch to trim the outboard motor for the best performance and stability.

You can use the power trim/tilt switch at any time, whether the boat is underway or stopped.

Press the UP or DN (down) side of the switch to adjust the angle of the outboard motor.

Refer to the trim meter (p. 31) for an indication of whether the outboard motor is trimmed high or low.

RPM, the Trolling Speed Control is deactivated. If 3,000 RPM is not reached and the throttle is closed, the engine speed will decrease to the Trolling Speed Control setting.

TRIM TAB

If steering effort is not equal in both directions, adjust the trim tab to compensate for “torque steer,” which is the reaction of the outboard motor to propeller rotation.

TRIM TAB BOLT TRIM TAB PROPELLER

Adjust the trim tab with the engine stopped. Loosen the trim tab bolt above the trim tab, turn the trim tab, and then tighten the bolt securely.

When the trim tab is correctly adjusted, steering effort will be equal in both directions.

Refer to TRIM TAB ADJUSTMENT on p. 72.

LHT, LRT and XRT Types

When operating in shallow water, use the power trim/tilt switch (p. 61) to tilt the outboard motor so that the propeller and gear case won't hit the bottom.

Proceed at low speed, and monitor water flow from the cooling system indicator (p. 34) to be sure the outboard motor is not tilted so high that the water intakes are out of the water.

NOTICE

An excessive trim/tilt angle during operation can cause propeller ventilation, overheating, and water pump damage. This type of damage is not covered by the Distributor's Limited Warranty (p. 124).

LH Type

When operating in shallow water, tilt the outboard motor, using the tilt lever, so the propeller and gear case won't hit the bottom.

To return the outboard motor to the normal operating position, move the tilt lever to the LOCK (RUN) position. You may need to raise the outboard motor slightly to disengage the tilt mechanism, and then slowly lower the outboard motor.

MOORING, BEACHING, LAUNCHING

Before tilting up, leave the outboard motor in the running position for one minute after stopping the engine to drain the water from inside the engine.

Stop the engine and disconnect the fuel hose from the outboard motor before tilting the outboard motor.

LH Type

Use the tilt lever to raise and lower the outboard motor as described on p. 64.

LHT, LRT and XRT Types

To raise the outboard motor out of the water while the engine is stopped and the boat is moored, or for maximum clearance when beaching or launching, use the power tilt switch on the engine pan to tilt the outboard motor up as far as it will go. Move the tilt lock lever to the LOCK position, and then gently lower the outboard motor until the lever contacts the stern bracket.

If more clearance is needed to swing the tilt lock lever into the LOCK position, rock the outboard motor forward slightly by pulling on the engine cover grip.

To lower the outboard motor, tilt up, move the tilt lock lever to the FREE position, and then lower the outboard motor to the desired position.

OPERATION

POWER (To fix) RIGHT STERN BRACKET MANUAL RELIEF VALVE MANUAL (To release)

The outboard motor can also be tilted manually after opening the manual relief valve. This feature enables the outboard motor to be tilted up or down when no battery is connected.

For manual tilting, use a flat blade screwdriver to turn the valve counterclockwise 2 and a half turns. Close the valve firmly after positioning the engine.

Check that nobody is under the outboard motor before opening the manual relief valve. If the manual relief valve is loosened (turned counterclockwise) when the outboard motor is tilted up, the outboard motor will suddenly tilt down.

Be sure the valve is closed before operating the outboard motor. If the valve is not closed, the outboard motor will tilt up when operated in reverse.

MULTIPLE OUTBOARD MOTORS

On boats equipped with more than one outboard motor, all motors normally operate at the same time.

If one or more motor(s) is stopped while the other(s) is running, put the stopped motor in “N” (neutral) and tilt it up so its propeller is above the water's surface.

If the propeller of the stopped motor is left in the water, it may turn as the boat moves through the water, causing a reverse flow of water from the exhaust side. This reverse flow will happen if the stopped engine's propeller is in the water, its gearshift is in "R" (reverse), and the boat is moving forward. Reverse flow can cause an engine malfunction.

STORAGE

Fuel

NOTICE

Depending on the region where you operate your outboard, fuel formulations may deteriorate and oxidize rapidly. Fuel deterioration and oxidation can occur in as little as 15 days and may cause damage to the fuel system. Please check with your servicing dealer for local storage recommendations.

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 vapor separator deteriorates during storage, you may need to have the vapor separator and other fuel system components serviced or replaced.

The length of time that gasoline can be left in your fuel tank and vapor separator 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 in less than 15 days, if the gasoline was not fresh when you filled the fuel tank.

You can extend fuel storage life by adding a gasoline stabilizer that is formulated for that purpose, or you can avoid fuel deterioration problems by draining all the fuel from the fuel tank and vapor separator.

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

Adding a Fuel Stabilizer

When adding a fuel stabilizer, fill the fuel tank with fresh gasoline. If only partially filled, air in the tank will promote fuel deterioration during storage. If you keep an additional container of gasoline for refueling, be sure that it contains only fresh gasoline.

  1. Drain the vapor separator before adding fuel stabilizer.
  2. Add Honda Marine fuel stabilizer following the instructions on the label.
  3. After adding a fuel stabilizer, run the engine in water for 10 minutes to be sure that the treated gasoline has replaced the untreated gasoline in the vapor separator.
  4. Turn the engine OFF.

Draining the Fuel System

You can avoid fuel deterioration problems by draining the fuel tank and vapor separator. Before draining and checking the fuel system, check the fuel filter for contamination and/or water accumulation. The fuel filter must be free of any contamination before proceeding (p. 84). Draining the vapor separator will not drain the fuel filter bowl.

TUBE CLAMPER DRAIN SCREW VAPOR SEPARATOR DRAIN TUBE

  1. Disconnect the fuel hose connector from the outboard motor (p. 84).
  2. Remove the engine cover (p. 73).
  3. Release the drain tube from its clamp along the high pressure fuel hose and set the end of the tube toward the outside of the engine undercase. Place an approved gasoline container below the end of the tube, and use a funnel to avoid spilling gasoline.
  4. Loosen the vapor separator drain screw.

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.

STORAGE

  1. Tilt the outboard motor up until gasoline flows out of the drain tube.
  2. Leave it in that position until the gasoline stops flowing.
  3. After thoroughly draining, tighten the drain screw securely.

  4. Check the drained gasoline for the presence of water or contamination. If either is present, you will have to reassemble and run the outboard to refill the vapor separator with gasoline and then drain it again. Repeat the following procedure until no water or contamination is present in the removed gasoline.

a. Make sure the gasoline supply is not contaminated.
b. Reassemble the outboard and reconnect the fuel line connector.
c. Place the outboard in water. Use the priming bulb to refill the fuel system and run the outboard at idle for 3 minutes.
d. Stop the outboard and follow the procedure beginning with step 1 above.

  1. Secure the drain tube to the clamp along the high pressure fuel hose.
  2. Install the engine cover.
  3. Drain the fuel tank into an approved gasoline container, or if you need to store fuel in the fuel tank, you can extend fuel storage life by filling the fuel tank with fresh gasoline and adding Honda Marine fuel stabilizer following the directions on the container. Close the fuel cap vent.
    If using the portable fuel tank, close the fuel filler cap vent knob. Store the portable fuel tank in a cool dry place out of direct sunlight.

Engine Oil

  1. Change the engine oil (p. 76).
  2. Remove the spark plugs (p. 78), and remove the emergency stop switch clip from the emergency stop switch.
  3. Pour 1 - 2 teaspoons (5 - 10 cm ^3 ) (p. 111) of clean engine oil into each cylinder.
  4. Using the emergency starter rope (p. 52), rotate the flywheel a few revolutions to distribute the oil in the cylinders.
  5. Reinstall the spark plugs (p. 79).

HOISTING THE OUTBOARD MOTOR

HOIST HOOK LIFTING EYE

  1. Unlatch and remove the engine cover (p. 73).
  2. Attach the hoist hook to the lifting eye.
  3. Disconnect the outboard motor from the boat, hoist the outboard motor, and move it to the storage area.

  4. After the outboard motor is placed in storage and disconnected from the hoist, install the engine cover.

STORAGE PRECAUTIONS

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

If storing a container of gasoline, such as the portable fuel tank (standard or optional equipment), 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.

STORAGE

OUTBOARD MOTOR STAND (commercially available)

If the outboard motor will be removed from the boat for storage, we recommend storing it vertically by mounting it on a commercially available stand.

CASE PROTECTOR CUSHION (protective material)

If it is necessary to store the outboard motor horizontally as shown, drain the vapor separator (p. 95), and drain the engine oil (p. 76), before removing the outboard motor from the boat.

Position the outboard motor with its case protector side down, and rest the outboard motor on a cushion of protective material.

NOTICE

Any other horizontal storage position may cause damage to the outboard motor or oil leakage.

Cover the outboard motor to keep out dust. Do not use plastic sheet 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 cylinders were coated with oil during storage preparation, the engine may smoke briefly at startup. This is normal.

TRANSPORTING

WITH OUTBOARD MOTOR INSTALLED ON BOAT

When trailering a boat with the outboard motor attached, always disconnect the fuel line from the portable fuel tank.

LH and LHT Types (tiller handle)

STEERING FRICTION ADJUSTER TO INCREASE FRICTION (LOCK) TO DECREASE FRICTION (FREE)

Tighten the steering friction adjuster to prevent the outboard motor from moving while trailing the boat.

LRT and XRT Types (remote control)

Use an outboard motor support bar to prevent the outboard motor from moving while trailering the boat. Refer to the manufacturer's instructions for using an outboard motor support bar.

NOTICE

  • Be careful to avoid connecting the battery in reverse polarity, as this will damage the battery-charging system in the outboard motor.
  • Do not disconnect the battery cables while the engine is running. Disconnecting the cables while the engine is running will damage the outboard motor's electrical system.

- Battery cable extension: Extending the original battery cable will cause the battery voltage to drop due to the increased length of the cable and number of connections. This voltage drop may cause the buzzer to sound momentarily when engaging the starter motor and may prevent the engine from starting. If the engine starts and the buzzer sounds momentarily, there may be barely sufficient voltage reaching the engine.

WARNING: Battery posts, terminals, and related accessories contain lead and lead compounds. Wash your hands after handling.

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 appropriate air/fuel ratios and other emissions control systems to reduce the emissions of carbon monoxide, oxides of nitrogen, and hydrocarbons.

Ignition Timing Control System

The system constantly adjusts the ignition timing, reducing the amount of HC, CO, and NOx produced.

TECHNICAL INFORMATION

PGM-FI System

The PGM-FI system uses sequential multiport fuel injection. It has two subsystems: Engine Control, and Fuel Control. The Engine Control Module (ECM) uses various sensors to determine how much air is going into the engine. It then controls how much fuel to inject under all operating conditions.

The U.S., California Clean Air Acts, and Environment Canada

EPA, California, and Canadian 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

NOTICE

Tampering is a violation of Federal and California law.

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.
  • Alterations that would 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 and California emission regulations. We recommend the use of Honda Genuine 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 p. 70. Remember that this schedule is based on the assumption that your machine will be used for its designed purpose. Sustained high-load operation, or use in unusual conditions, will require more frequent service.

If you have a difference of opinion with your dealer, please remember that each dealership is independently owned and operated. That's why it's important to work to resolve any differences at the dealership level. If the service personnel are unable to assist you, please discuss your concerns with the dealer management such as the Service Manager or the dealership's owner.

Warranty Coverage

Your new Honda is covered by the following warranties:

  • Distributor's Limited Warranty
  • Emission Control System Warranty

Please read the warranty statements contained in this manual. There are responsibilities, restrictions, and exclusions that apply to these warranties.

To obtain warranty service you must take your Honda outboard motor, together with proof of original retail purchase date, at your expense, to a Honda engine dealer or distributor authorized to sell that product in the United States, Puerto Rico, the U.S. Virgin Islands or Canada.

It is important to realize that your warranty applies to defects in material or workmanship of your Honda. Your warranty coverage does not apply to normal wear or deterioration associated with using your Honda outboard motor.

Your warranty coverage will not be voided if you choose to perform your own maintenance. However, you should have the proper tools and service information and be mechanically qualified. Failures that occur due to modifications, improper maintenance, or service are not covered.

Warranty Service

Please remember that recommended maintenance interval servicing is not included in your warranty coverage. Additionally, your warranty does not apply to the normal wear of items (such as spark plug(s), water pump, etc.).

As the owner of a Honda product, your servicing dealer may ask you to authorize an inspection. If the problem is covered under warranty, your dealer will perform any warranty repairs for you at no cost. However, you may be responsible for additional non-warranty charges.

If you have questions about warranty coverage or the nature of the repair, it is best to talk to the service manager of your Honda dealer.

Sometimes, in spite of the best intentions of all concerned, a misunderstanding may occur. If you

aren't satisfied with your dealer's handling of the situation, we suggest you discuss your problem with the appropriate member of the dealership's management team. If the problem has already been reviewed with the appropriate manager of the Service, Parts, or Sales department, contact the owner of the dealership or their designated representative.

Any implied warranties are limited to the duration of this written limited warranty.

Emission Control System Warranty

Your new Honda outboard engine complies with both the U.S. EPA and State of California emission regulations. American Honda provides the same emission warranty coverage for outboard engines sold in all 50 states. In all areas of the United States your outboard engine must be designed, built, and equipped to meet the U.S. EPA and California Air Resources Board emission standard for spark ignited marine engines.

CALIFORNIA EMISSION CONTROL WARRANTY STATEMENT YOUR WARRANTY RIGHTS AND OBLIGATIONS

The California Air Resources Board (CARB) and American Honda Motor Co., Inc. are pleased to explain the emission control system warranty on your 2013-2014 Honda outboard engine. In California, new outboard engines must be designed, built, and equipped to meet the state's stringent anti-smog standards. American Honda Motor Co., Inc. must warrant the emission control system on your outboard engine for the periods of time listed below provided there has been no

abuse, neglect, or improper maintenance of your outboard engine.

Your emission control system may include parts such as the carburetor or fuel injection system, the ignition system, and catalytic converter. Also included may be hoses, belts, connectors, and other emission-related assemblies.

Where a warrantable condition exists, American Honda Motor Co., Inc. will repair your outboard engine at no cost to you including diagnosis, parts, and labor.

MANUFACTURER'S WARRANTY COVERAGE:

Select emission control parts from model year 2010 and later outboard engines are warranted for five years or 250 hours of use, whichever first occurs; or the length of the Honda Marine Distributor's Limited Warranty, whichever is longer. However, warranty coverage based on the hourly period is only permitted for engines equipped with hour meters as defined in § 2441 (a)(13)* or their equivalent. If any emission-related part on your engine is defective under warranty, the part will be repaired or replaced by American Honda Motor Co., Inc.

* California Code of Regulations.

CONSUMER INFORMATION

OWNER'S WARRANTY RESPONSIBILITIES:

As the outboard engine owner, you are responsible for the performance of the required maintenance listed in your owner's manual. American Honda Motor Co., Inc. recommends that you retain all receipts covering maintenance on your outboard engine, but American Honda Motor Co., Inc. cannot deny warranty solely for the lack of receipts or your failure to ensure the performance of all scheduled maintenance.

As the outboard engine owner, you should, however, be aware that American Honda Motor Co., Inc. may deny you warranty coverage if your outboard engine or a part has failed due to abuse, neglect, improper maintenance, or unapproved modifications.

You are responsible for presenting your outboard engine to a Honda Marine dealer as soon as a problem exists. The warranty repairs will be completed in a reasonable amount of time, not to exceed 30 days.

If you have any questions regarding your warranty rights and responsibilities, you should contact American Honda Motor Co., Inc., Marine Division Customer Relations Office. Please see Contacting Honda page 121.

WARRANTY COVERAGE:

Honda outboard engines certified to the CARB and EPA 2010 and later regulation are covered by this warranty to be free from defects for a minimum of five years or 250 hours of operation, whichever comes first; or the length of the Honda Marine Distributor's Limited Warranty, whichever is longer, from the date of delivery to the retail purchaser. This warranty is transferred to each subsequent purchaser for the duration of the warranty period. Warranty repairs will be made without charge for diagnosis, parts, and labor. All defective parts replaced under this warranty become the property of American Honda Motor Co., Inc. A list of warranty parts is on page 132. Normal maintenance items, such as spark plugs and filters, that are on the warranted parts list are warranted up to their required replacement interval only. American Honda Motor Co., Inc. is also liable for damages to other engine components caused by a failure of any warranted part during the warranty period. Only Honda approved replacement parts will be used in the performance of any warranty repairs, and they will be provided without charge to the owner. You may use any replacement part as defined in § 1900 (b)(20)* in the performance of any maintenance or repairs. If a replacement part is used in the repair or maintenance of your engine, and an authorized Honda Marine dealer determines it causes the failure of a warranted part, your warranty claim may be denied. If the part in question is not related to the reason that your engine requires repair, your claim will not be denied.

* California Code of Regulations.

TO OBTAIN WARRANTY SERVICE:

You must take your Honda outboard engine, along with your sales registration card or other proof of original purchase date, at your expense, to any Honda Marine dealer that is authorized by American Honda Motor Co., Inc. to sell and service that Honda marine product during its normal business hours. Claims for repair or adjustment found to be caused solely by defects in material or workmanship will not be denied because the engine was not properly maintained and used. If you are unable to obtain warranty service, or are dissatisfied with the warranty service you received, contact the owner of the dealership involved. Normally this should resolve your problem. However, if you require further assistance, write or call the Honda Marine Customer Relations Office of American Honda Motor Co., Inc.

EXCLUSIONS:

Failures other than those resulting from defects in material or workmanship are not covered by this warranty. This warranty does not extend to emission control systems or parts which are affected or damaged by owner abuse, neglect, improper maintenance, misuse, misfueling, improper storage, and/or collision, the incorporation of, or use of, unsuitable attachments, or the unauthorized alteration of any part.

This warranty does not cover replacement of expendable maintenance items made in connection with required maintenance service after the items first scheduled replacement as listed in the maintenance section of the product owner's manual, such as: spark plugs and filters.

DISCLAIMER OF CONSEQUENTIAL DAMAGE AND LIMITATION OF IMPLIED WARRANTIES:

American Honda Motor Co., Inc. disclaims any responsibility for incidental or consequential damages such as loss of time or the use of outboard engine, or any commercial loss due to the failure of the equipment; and any implied warranties are limited to the duration of this written warranty. This warranty is applicable only where the California or U.S. EPA emission control system warranty regulation is in effect.
