OUTBOARD MOTOR SAFETY
IMPORTANT SAFETY
INFORMATION
The Honda BF4A, BF5D and BF6A
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.
31ZVC6150.book Page 6 Friday, October 13, 2023 1:41 PM

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.
• Remove any portable fuel tank
from the boat for refueling. Keep
the portable fuel tank away from
the battery or other potential spark
sources.
• 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.
Running the engine of your
outboard while in an enclosed or
partially enclosed area can cause
a rapid build-up of toxic carbon
monoxide gas.
Breathing this colorless, odorless
gas can quickly cause
unconsciousness and lead to
death.
Only run your outboard engine
when it is located in a well
ventilated area outdoors.

cooling system problem, such as
clogged water intakes, which will
cause engine overheating.
OTHER FEATURES
Rev Limiter
The engine is equipped with a rev
limiter to prevent the possibility of
mechanical damage from excessive
engine speed.
The rev limiter may be activated
during operation, limiting engine
speed, if the outboard motor is tilted
excessively, or when propeller
ventilation occurs during a sharp turn.
If the rev limiter is activated, check
the tilt angle of the outboard motor.
Improper propeller selection may also
cause the rev limiter to activate.
Check to see if the correct propeller is
installed.
Anode
The anode is made of a sacrificial
material that helps to protect the
outboard motor from corrosion.
There is an anode on the
antiventilation plate.

INSTALLATION
Correct and secure installation is
essential for safe boating and good
performance. Follow the installation
instructions provided in this manual.
POWER REQUIREMENTS
Before installation, check to be sure
that the outboard motor does not
exceed the recommended maximum
horsepower for the boat on which it is
to be installed. Refer to the boat’s
certification plate for recommended
maximum horsepower. If the
certification plate information is not
available, contact the boat dealer or
manufacturer.
For most applications, the outboard
motor should have a horsepower
rating which provides 80% of the
maximum recommended horsepower
for the boat.
INSTALLATION POSITION
Install the outboard motor on the
center of the boat transom.
The antiventilation plate of the
outboard motor should be 0 – 2 in
(0 – 50 mm) below the bottom of the
boat.
The correct dimensions differ
according to the type of boat and the
configuration of the bottom of the
boat. Follow the manufacturer’s
recommended installation height.
When the outboard motor is installed
extremely low, the idle port may be
immersed and the engine may
become hard to start or may run
poorly. Check that the idle port is
high enough from the water level
when the engine is stopped with the
boat fully loaded.

INSTALLATION
If the outboard motor is installed too
low, the boat will squat and be hard to
plane, and the outboard motor will
spray water that may enter the boat. It
will tend to bounce, and high-speed
stability will be reduced.
If the outboard motor is installed too
high, that will cause propeller
ventilation.
Optimum installation height varies
with boat type and bottom shape.
Contact the boat manufacturer for any
special recommendations that are
unique to a specific model of boat.
If the transom needs to be modified to
accommodate the outboard motor,
contact the boat manufacturer and
follow their recommendations for
corrective action.
ATTACHMENT
Attach the stern bracket to the boat
transom by tightening the clamp
screws.
Attach a rope from the boat to the
hole in the stern bracket. This will
help to prevent accidental loss of the
outboard motor.
TRANSOM ANGLE
ADJUSTMENT
Use the transom angle adjusting rod
(p. 37) to adjust the angle of the
outboard motor so the propeller is
perpendicular to the surface of the
water.

INSTALLATION
BATTERY CONNECTIONS
An optional accessory charging kit is
available for Honda BF4A, BF5D,
and BF6A outboard motors and can
produce a 12-volt, 6-ampere battery
charging current to charge a 12-volt
battery. The battery charging circuit is
protected by a 15-ampere fuse.
The outboard motor's optional
accessory 12-volt charge kit is
designed to charge a ‘‘starting or
cranking’’ type battery only. It is not
intended to charge a ‘‘deep-cycle’’
type battery. Lights and electrical
accessories for the boat should be
connected to the battery.
The battery should be kept 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.
Battery
For complete information, refer to the
battery manufacturer's instructions.
Minimum Requirements
12V-28Ah/5HR (CCA 265)
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.

INSTALLATION
Battery Terminals
WARNING: Battery posts,
terminals, and related accessories
contain lead and lead compounds.
Wash hands after handling.
Connect the positive (+) battery cable
(red terminal cover) to the positive
(+) battery terminal, then connect the
negative (-) battery cable (black
terminal cover) to the negative (-)
battery terminal.
The negative (-) battery cable should
always be removed from the battery
before 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.
• 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.
The outboard may not start if the
battery voltage reaching the engine
is too low.

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 6 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
Proper break-in procedure allows the
moving parts to wear in smoothly for
best performance and long service life.
• First 15 minutes: Run the outboard
motor at trolling speed. Use the
minimum amount of throttle
opening necessary to operate the
boat at a safe trolling speed.
• Next 45 minutes: Run the outboard
motor up to a maximum of 10% to
30% throttle opening.
• Next 60 minutes: Run the outboard
motor up to maximum of 50% to
80% throttle opening. Short bursts
of full throttle are acceptable but do
not operate the outboard motor
continuously at full throttle.
• Next 8 hours: Avoid continuous
full throttle operation (100%
throttle opening). Do not run the
outboard motor at full throttle for
more than 5 minutes at a time.
Exhaust contains poisonous
carbon monoxide gas that can
build up to dangerous levels in
closed areas.
Breathing carbon monoxide can
cause unconsciousness or death.
Never run this product's engine in
a closed, or even partially closed
area.

OPERATION
CRUISING
Engine Speed
For best fuel economy, limit the
throttle opening to 80%. Use the
throttle friction control (p. 53) 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.
Transom Angle
Install the outboard motor at the best
transom angle for stable cruising and
maximum power.
Transom angle too large: Causes boat
to ‘‘squat.’’
Transom angle too small: Causes boat
to ‘‘bow steer.’’
It is necessary to adjust the transom
angle of the outboard motor to
compensate for changes in boat load,
weight distribution, water conditions,
or propeller selection.
Under normal running conditions, the
boat will perform best when the
antiventilation plate is level with the
water surface.
When cruising into a high wind,
adjust the outboard motor down
slightly to level the boat and improve
stability. With a tail wind, adjust the
outboard motor up slightly (p. 37).
Excessive transom 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 (U.S.) /
Distributor’s Warranty (CA.) (p. 112).

OPERATION
SHALLOW WATER
OPERATION
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 tilt the outboard motor, raise the
outboard motor to the 18° position by
pulling on the engine cover grip.
Do not use the tiller handle as a lever
to raise the outboard motor. Applying
excessive force to the tiller handle
can damage it.
While the outboard motor is tilted,
proceed at a low speed, and do not
operate the outboard motor in
reverse. The outboard motor will rise
suddenly if operated in reverse.
Monitor water flow from the cooling
system indicator (p. 25) to be sure the
outboard motor is not tilted so high
that the water intakes are out of the
water.
An excessive 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 (U.S.) / Distributor’s

THE IMPORTANCE OF
MAINTENANCE
Proper maintenance is essential for
safe, economical, and trouble-free
operation. It will also help reduce air
pollution.
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.
Failure to properly maintain this
outboard motor, or failing to
correct a problem before
operation, could result in a
significant malfunction.
Some malfunctions can cause
serious injuries or death.
Always follow the inspection and
maintenance recommendations
and schedules in this owner's
manual.

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.
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.
Improper maintenance can cause
an unsafe condition.
Failure to properly follow
maintenance instructions and
precautions can cause serious
injuries or death.
Always follow the procedures
and precautions in this owner’s

FUEL RECOMMENDATIONS
Use unleaded gasoline with a pump
octane rating of 86 or higher.
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 use gasoline that is stale,
contaminated, or mixed with oil.
Avoid getting dirt or water in the fuel
tank.
You may use unleaded gasoline
containing no more than 10% ethanol

STORAGE
Fuel
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
carburetor and fuel system.
Please check with your servicing
dealer for local storage
recommendations.
Gasoline will oxidize and deteriorate
in storage. Deteriorated 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
components 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 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 carburetor.
The
Distributor’s Limited Warranty (U.S.)
/ Distributor’s Warranty (CA.)
(p. 112)
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
internal fuel tank with fresh gasoline.
If only partially filled, air in the
internal fuel 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. Add Honda Marine fuel stabilizer
or equivalent following the
instructions on the label.
2. 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 carburetor.
3. Stop the engine (p. 51).

OIL PRESSURE INDICATOR
GOES OFF AND ENGINE
SPEED IS LIMITED
If oil pressure becomes low, the green
indicator will go off. If you are at
cruising speed, engine speed will
decrease gradually.
Low oil pressure may be the result of
a low engine oil level, or there may
be a problem with the engine
lubrication system.
If the throttle is closed suddenly after
full throttle operation, engine speed
may drop below the specified idle
rpm, and that could activate the
engine protection system
momentarily.
If low oil pressure activates the
engine protection system, stop the
engine, check the engine oil level
(p. 64), and add oil if needed.
With the engine oil at the
recommended level, restart the
engine. If the lubrication system is
OK, the green indicator should come
on within 30 seconds, and the engine
will respond normally to throttle grip
operation.
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 Marine dealer.

TAKING CARE OF UNEXPECTED PROBLEMS
SUBMERGED OUTBOARD
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 outboard motor to the
dealer immediately. If you are far
from a dealer, proceed as follows:
1. Unlock and remove the engine
cover (p. 63), and rinse the
outboard motor with fresh water to
remove salt water, sand, mud, etc.
2. Drain the internal fuel tank and
carburetor as described on p. 85.
3. Change the engine oil as described
on p. 65. 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.
4. Remove the spark plug (p. 70), and
remove the emergency stop switch
clip from the emergency stop
switch. Pull the starter grip, rotate
the flywheel a few revolutions to
completely expel any water from
the cylinder.
If the engine was running when it
submerged, there may be
mechanical damage, such as a bent
connecting rod. If the engine binds
when cranked, do not attempt to
run the engine until it has been
repaired.
When cranking the engine with an
open ignition circuit (spark plug
removed from the ignition circuit),
remove the emergency stop switch
clip from the emergency stop switch
to prevent possible damage to the
ignition system.

5. Pour a teaspoon (5 - 10 cm
3
) of
engine oil into the spark plug hole,
and then pull the starter grip
several times to lubricate the inside
of the cylinder.
6. Reinstall the spark plug, and put
the emergency stop switch clip into
the emergency stop switch.
7. Attempt to start the engine. Be sure
the water level is at least 2 inches
(5 cm) above the antiventilation
plate.
If the engine fails to start, remove
the spark plug, clean and dry it,
then reinstall the spark plug 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.
8. As soon as possible, take the
outboard motor to an authorized
Marine dealer for inspection and
service.

TECHNICAL INFORMATION
Carburetor Modification for
High Altitude Operation
At altitudes above 3,000 feet
(900 meters), 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.
Operation at an altitude that differs
from that at which this engine was
certified, for extended periods of
time, may increase emissions.
High altitude operation can be
improved by specific modifications
to the carburetor. If you usually
operate your outboard motor at 3,000
feet (900 meters) or above, consult
with your authorized Honda Marine
dealer.
Your dealer can determine the
appropriate carburetor settings for the
altitude at which you operate your
outboard motor.
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.
When the carburetor has been
modified for operation at one of the
higher altitude ranges, the air-fuel
mixture will be too lean for operation
at a lower altitude.
Operation at altitudes below the
range for which the carburetor is set
may cause the engine to overheat and
result in serious engine damage.
For use at lower altitudes, have an
authorized Marine dealer modify the
carburetor for the correct altitude
range.

TECHNICAL INFORMATION
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.
The U.S., California Clean Air
Acts, and Canadian
Environmental Protection Act
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
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.

TECHNICAL INFORMATION
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.
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.
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. 61 and 62). 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.

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 EMISSIONS CONTROL SYSTEM
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 2024 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, catalytic converter, canisters, clamps, filters, fuel
caps, fuel lines, fuel tanks, valves, and vapor hoses. 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. The evaporative emission
control system from model year 2010 and later outboard
engines are warranted for two years with no limit on hours
of use, or the length of the Honda Marine Distributor’s
Limited Warranty, whichever is longer, from the date of
delivery to the retail purchaser. 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. See the Emission Control System Warranty Parts
table on page 121 for parts description.
* California Code of Regulations.
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.

WARRANTY COVERAGE:
See Manufacturer’s Warranty Coverage above for
warranty coverage terms. 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
121. 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. Honda cannot
deny coverage under the emission warranty solely for use
of non-Honda replacement parts or service performed at a
location other than an authorized Honda dealership;
however, use of a part that is not functionally identical to
the original equipment part in any respect that may in any
way affect emissions (including durability) could result in
denial of coverage. If a non-Honda 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.
