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.

09/06/22 21:22:56 31ZZ4610_009

OUTBOARD MOTOR SAFETY
Refuel With Care
Gasoline is extremely flammable,
and gasoline vapor can explode.
Refuel outdoors, in a wellventilated 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.

OUTBOARD MOTOR SAFETY
Canadian Types

Honda outboard motor is
designed to give safe and
dependable service if
operated according to
instructions.
Read and understand the
Owner’s Manual before
operating the outboard
motor. Failure to do so
could result in personal
injury or equipment
damage.

Gasoline is harmful or fatal
if swallowed. Keep the fuel
tank out of reach of
children.
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.

OPERATION
SAFE OPERATING
PRECAUTIONS

BREAK-IN PROCEDURE
Break-in period: 10 hours

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.

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

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.
Short full-throttle bursts are OK, but
do not operate the engine
continuously at full throttle.

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

First 15 minutes:
Run the engine at trolling speed. Use
the minimum throttle opening
necessary to operate the boat at a safe
trolling speed.

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

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.

Next 45 minutes:

Next 8 hours:

Run the engine up to a maximum of
2,000 to 3,000 rpm, which is about
10% to 30% of maximum throttle
opening.

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

CRUISING
Engine Speed
For best fuel economy, limit the
throttle opening to 80%. Use the
throttle friction control (p. 58 , 59 )
to help you hold a steady speed.

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

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.

LH Type
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.

LHT, LRT and XRT Types
Install the outboard motor at the best
trim angle for stable cruising and
maximum power.
Trim angle too large: Incorrect
causes boat to ‘‘squat.’’
Trim angle too small: Incorrect
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.

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 motor is
trimmed high or low.

THE IMPORTANCE OF
MAINTENANCE
Proper maintenance is essential for
safe, economical, and trouble-free
operation. It will also help reduce air
pollution.

Improperly maintaining
this outboard motor or
failure to correct a problem
before operation can cause
a malfunction in which you
could be seriously hurt or
killed.
Always follow the
inspection and
maintenance
recommendations and
schedules in this Owner’s
Manual.

To help you properly care for your
outboard motor, the following pages
include a maintenance schedule,
routine inspection procedures, and
simple maintenance procedures using
basic hand tools. Other service tasks
that are more difficult or require
special tools are best handled by
professionals and are normally
performed by a Honda technician or
other qualified mechanic.
The maintenance schedule applies to
normal operating conditions. If you
operate your outboard motor under
unusual conditions, consult an
authorized Honda Marine dealer for
recommendations applicable to your
individual needs and use.

Remember that your authorized
Honda Marine dealer knows your
outboard motor best and is fully
equipped to maintain and repair it.
To ensure the best quality and
reliability, use only new, Honda
Genuine parts or their equivalents for
repair and replacement.
Maintenance, replacement, or
repair of the emission control
devices and systems may be
performed by any marine engine
repair establishment or individual,
using parts that are ‘‘certified’’ to
EPA standards.

MAINTENANCE SAFETY
Some of the most important safety
precautions follow. However, we
cannot warn you of every
conceivable hazard that can arise in
performing maintenance. Only you
can decide whether or not you should
perform a given task.

Failure to properly follow
maintenance instructions
and precautions can cause
you to be seriously hurt or
killed.
Always follow the
procedures and
precautions in the Owner’s
Manual.

Safety Precautions
Make sure the engine is off before
you begin any maintenance or
repairs. This will eliminate several
potential hazards:
−Carbon monoxide poisoning
from engine exhaust.
Do not start or run the engine in
a confined or partly enclosed
area.
−Burns from hot parts.
Let the engine and exhaust
system cool before touching.
−Injury from moving parts.
Do not run the engine unless
instructed to do so.

Read the instructions before you
begin, and make sure you have the
tools and skills required.
To reduce the possibility of fire or
explosion, be careful when
working around gasoline. Use only
a nonflammable solvent, not
gasoline, to clean parts. Keep
cigarettes, sparks, and flames away
from all fuel-related parts.
Wear gloves when handling the
propeller to protect your hands
from sharp edges.

FUEL RECOMMENDATIONS
Gasoline is highly
flammable and explosive.

Use unleaded gasoline with a pump
octane rating of 86 or higher.

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.

Your outboard motor is certified to
operate on unleaded gasoline.
Unleaded gasoline produces fewer
engine and spark plug deposits and
extends exhaust system life.

Never refill the fuel tank inside a
building where gasoline fumes may
reach flames or sparks. Keep
gasoline away from appliance pilot
lights, barbecues, electric appliances,
power tools, etc.
Spilled fuel is not only a fire hazard,
it causes environmental damage.
Wipe up spills immediately.

Never use stale or contaminated
gasoline or an oil/gasoline mixture.
Avoid getting dirt or water in the fuel
tank.

Engine damage or performance
problems that result from using a fuel
with percentages of ethanol or
methanol greater than shown above
are not covered under warranty.
If your outboard will be used on an
infrequent or intermittent basis,
please refer to the fuel section of the
STORAGE chapter (p. 92 ) for
additional information regarding fuel
deterioration.

You may use unleaded gasoline
containing no more than 10% ethanol
(E10) or 5% methanol by volume. In
addition, methanol must contain
cosolvents and corrosion inhibitors.
Use of fuels with content of ethanol
or methanol greater than shown
above may cause starting and/or
performance problems. It may also
damage metal, rubber, and plastic
parts of the fuel system.

STORAGE
STORAGE PREPARATION

Cleaning

Proper storage preparation is
essential for keeping your outboard
motor trouble-free 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.

Wash the outside of the outboard
motor with clean, fresh water, and
flush the cooling system as follows.

Cleaning and Flushing
Thoroughly clean and flush the
outboard motor with fresh water after
operation in dirty water or salt water.
Touch up any damaged paint, and
coat areas that may rust with Honda
Corrosion Inhibitor, or equivalent.
Lubricate controls with a silicone
spray lubricant.

Do not apply water or corrosion
inhibitor directly to the electrical
components under the engine cover,
such as the HO2 sensor and timing
belt. If water or corrosion inhibitor
penetrates these components, they
may be damaged. Bef ore applying a
corrosion inhibitor, cover the HO2
sensor and timing belt with a
protective material to prevent
damage.

Flushing With a Garden Hose
Garden Hose Adapter (optional
equipment)
It is necessary to run the engine
during the flushing procedure. For
safety, remove the propeller from the
outboard motor (p. 87 ).

WASH SCREW
(flush screw)

1. Remove the wash screw and
sealing washer from the WASH
screw hole in the gear case. Be
sure not to remove the oil level
screw from the OIL LEVEL screw
hole in the gear case.

STORAGE
GARDEN HOSE ADAPTER
(FLUSH KIT COUPLER)

4. Move the gearshift lever or control
lever to the N (neutral) position.
Flush the outboard motor in the
neutral position only.
5. Turn on the fresh water supply to
the flush kit coupler.
Running the engine without good
water circulation can cause
overheating and water pump damage.

2. Remove the sealing washer from
the wash screw and install the
sealing washer on the flush kit
coupler.
3. Install the flush kit coupler into the
WASH screw hole and connect a
fresh water hose to the garden
hose adapter.

Damage caused by running the
outboard motor without sufficient
cooling water is not covered by the
Distributor’s Limited Warranty
(p. 122 ).

COOLING SYSTEM INDICATOR

6. Start the engine. Monitor the
cooling system indicator. Stop the
engine if water does not come out
of the cooling system indicator and
check the fresh water supply.
If the fresh water supply is
insufficient it may be necessary
to temporarily cover the three
water intakes with duct tape as
shown on the following page.

09/06/22 21:38:06 31ZZ4610_093

STORAGE
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
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 within a few
months, or even less 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 fuel stabilizer following the
manufacturer’s instructions.
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.

09/06/22 21:38:18 31ZZ4610_094

STORAGE
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. 82 ). Draining
the vapor separator will not drain the
fuel filter bowl.

6. Leave it in that position until the
gasoline stops flowing.
7. After thoroughly draining, tighten
the drain screw securely.

8. 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

outboard at idle for 3 minutes.
d. Stop the outboard and follow
the procedure beginning with
step 1 above.

9. Secure the drain tube to the clamp
along the high pressure fuel hose.
10. Install the engine cover.
11. 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 a fuel
stabilizer that is formulated for
that purpose.

Normal

If the engine is stopped after running
at full throttle, and then restarted
soon afterward, that could activate
the engine protection system
momentarily.

Abnormal

If the engine overheats, the overheat
indicator will come on, and the
engine will stop in 20 seconds after
the engine protection system limits
engine speed. If you are at cruising
speed, engine speed will decrease
automatically.
All types are equipped with a buzzer
that sounds when the overheat
indicator comes on.
Engine overheating may be the result
of restricted water intake screens, or
there may be a problem with the
cooling system thermostat or water
pump.

COOLING SYSTEM INDICATOR

If overheating activates the engine
protection system, idle the engine in
neutral, and check the cooling system
indicator.

If water is flowing from the cooling
system indicator, continue idling for
30 seconds. If the cooling system is
OK, the overheat indicator should go
off within 30 seconds, and the engine
will respond normally to throttle
control lever operation.
If there is no water flowing from the
cooling system indicator, stop the
engine, and tilt the outboard motor to
inspect the water intake screens. If
restricted, clean the water intake
screens, return the outboard motor to
the running position, restart the
engine, and check the cooling system
indicator again.
If there is still no water flowing from
the cooling system indicator, or if the
engine protection system remains
activated after 30 seconds, return to
the nearest boat landing, and have the
outboard motor inspected by an
authorized Honda Marine dealer.

TAKING CARE OF UNEXPECTED PROBLEMS
SUBMERGED MOTOR
A submerged outboard 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 to the dealer
immediately. If you are far from a
dealer, proceed as follows:

3. Change the engine oil as described
on p. 75 − 77 . If there was water
in the engine crankcase, or if the
used engine oil showed signs of
water contamination, then a second
engine oil change should be
performed after running the engine
for half an hour.

If the engine was running when it
submerged, there may be
mechanical damage, such as bent
connecting rods. If the engine
binds when cranked, do not
attempt to run the engine until it
has been repaired.

1. Remove the engine cover, and
rinse the outboard motor with
fresh water to remove salt water,
sand, mud, etc.
2. Drain the vapor separator as
described on p. 93 .

EMERGENCY STARTER ROPE

4. Remove the alternator cover (p.
52 ).

108

5. Remove the spark plugs (p. 77 ),
and remove the emergency stop
switch clip from the emergency
stop switch. Pull the emergency
starter rope, rotate the flywheel a
few revolutions to completely
expel any water from the engine’s
cylinders.

When cranking the engine with an
open ignition circuit (spark plugs
removed f rom the ignition circuit),
remove the clip f rom the
emergency stop switch to prevent
possible damage to the ignition
system.

09/06/22 21:41:26 31ZZ4610_110

TAKING CARE OF UNEXPECTED PROBLEMS
8. Attempt to start the engine. Be
sure the water level is at least 2
inches (5 cm) above the
antiventilation plate.

9. As soon as possible, take the
outboard motor to an authorized
Honda Marine dealer for
inspection and service.

Running the outboard motor without
suf f icient cooling water will damage
the water pump and overheat the
engine.

6. Pour 1−2 teaspoons (5−10 cm3)
of engine oil into each spark plug
hole, then pull the emergency
starter rope several times to
lubricate the inside of the cylinders.
7. Reinstall the spark plugs and
alternator cover, and put the
emergency stop switch clip into
the emergency stop switch.

If the engine fails to start, remove
the spark plugs and dry them, then
reinstall the spark plugs and
attempt to start the engine again.
If the engine starts, and no
mechanical damage is evident,
continue to run the engine for a
half hour or longer. Be sure the
water level is at least 2 inches (5
cm) above the antiventilation plate
to avoid overheating and water
pump damage.

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.

111

09/06/22 21:41:56 31ZZ4610_113

TECHNICAL AND CONSUMER 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.

112

The U.S. and Calif ornia Clean
Air Acts
EPA and California 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.
Alterations that would cause the
engine to operate outside its design
parameters.

TECHNICAL AND CONSUMER INFORMATION
Problems That May Af f ect
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

Maintenance

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.

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.

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.

YOUR WARRANTY RIGHTS AND OBLIGATION
California
The California Air Resources Board and American
Honda Motor Co., Inc. are pleased to explain the
emission control system warranty on your 2001 and later

must be designed, built, and equipped to meet the U.S.
EPA Emission Standard for spark ignited marine engines.
American Honda Motor Co., Inc. must warranty the

TECHNICAL AND CONSUMER INFORMATION
OWNER’S WARRANTY RESPONSIBILITY:
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 for 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 repair should 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 119 .

WARRANTY COVERAGE:
Honda outboard engines certified to the CARB and EPA
2010 regulations are covered by this warranty 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
129 . 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. The use of
replacement parts not equivalent to the original parts may
impair the effectiveness of your engine’s emission
control system. If such a replacement part is used in the
repair or maintenance of your engine, and an authorized
Honda Marine dealer determines it is defective or causes
a failure of a warranted part, your claim for your engine

127

09/06/22 21:45:38 31ZZ4610_129

TECHNICAL AND CONSUMER INFORMATION
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.
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 who is authorized by American Honda Motor Co.,
Inc. to sell and service that Honda Marine product during
his 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.

128

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 item’s 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.
