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 boat applications, the outboard motor should have a horsepower
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. When the outboard motor is
mounted on a sailboat, the
antiventilation plate should be 6 in
(150 mm) or more below the surface
of the water. For unusual situations,
see your Honda marine dealer for
advice.

The correct dimensions differ
according to the type of boat and
the configuration of the bottom of
the boat. Follow the manufacture’s
recommended installation height.

INSTALLATION

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.

If the outboard motor is installed too low, the boat will squat and be hard
to plane, and the motor will spray water that may enter the boat. It will tend
to porpoise, and high-speed stability will be reduced.

Propeller ventilation will occur if the outboard motor is installed too high on the
boat transom.

Optimum installation height varies with boat type and bottom shape. Contact
the boat manufacturer for any spacial 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.

OUTBOARD MOTOR ATTACHMENT

Attach the stern bracket to the boat
transom by tightening the clamp
screws.

NOTICE

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.

•

The holes in the clamp screw
handles may be padlocked together
to prevent theft of the motor.

BATTERY

Battery Connections

Honda BF8A outboard motors produce a 12-volt, 5-ampere battery-charging
current. The motors come with a DC receptacle that needs to be connected
to a 12-volt battery. The battery-charging circuit is protected by a 5-ampere
fuse located in the engine compartment.

The outboard motor’s 12-volt output is designed to charge a “starting or
cruising” 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.

INSTALLATION

Battery Installation

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

+ WARNING

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

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

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

EMERGENCY PROCEDURES

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

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

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

23

INSTALLATION

Connections to the Battery

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

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

NOTICE

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

STORING YOUR OUTBOARD MOTOR

Storage Preparation

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.

Cleaning and Flushing

Wash the outside of the outboard motor with clean, fresh water, and flush the
cooling system as described on page 46 or 47.

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

Touch up any damaged paint, and coat areas that may rust with Honda
Corrosion Inhibitor, or equivalent. Lubricate controls with a silicone spray
lubricant.

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 carburetors and 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 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 30 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.

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 a
container of gasoline for refueling, be sure that it contains only fresh gasoline.

1. Add fuel stabilizer following the manufacturer’s instructions.

2. After adding a fuel stabilizer, run the engine outdoors for 10 minutes to be sure
that the treated gasoline has replaced the untreated gasoline in the carburetor.

HELPFUL TIPS AND SUGGESTIONS

Storage Precautions

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

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

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

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

NOTICE

Any other storage position may cause damage or oil leakage.

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

63

HELPFUL TIPS AND SUGGESTIONS

Removal From Storage

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

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

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

2. Loosen the carburetor drain screw (p. 62), drain the contents of the
carburetor into a suitable container, then tighten the drain screw.

3. Change the engine oil (p. 49). 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
1/2 hour.

4. Remove the spark plugs (p. 54). Disengage the emergency engine stop
switch clip from the engine stop switch and pull the starter grip, rotate the
flywheel a few revolutions to completely expel water from the cylinders.

STARTER GRIP

NOTICE

When cranking the engine with an open ignition circuit (spark plugs

•

removed from the ignition circuit), disengage the emergency engine stop
switch clip from the engine stop switch to prevent electrical damage to the
ignition system.

•

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.

67

TAKING CARE OF UNEXPECTED PROBLEMS

5. Pour a teaspoon of engine oil into the spark plug hole, then pull the starter
grip several times to lubricate the inside of the cylinders. Reinstall the spark
plug and engage the emergency engine stop switch clip with the engine
stop switch.

STARTER GRIP

6. Attempt to start the engine.

• If the engine fails to start, remove the spark plug, clean and dry the

electrode, 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 1/2 hour or longer (be sure the water level is at least
2 inches above the antiventilation plate).

7. As soon as possible, take the motor to an authorized Honda marine dealer
for inspection and service.

TECHNICAL AND CONSUMER INFORMATION

Carburetor Modification for High Altitude Operation

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

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

Even with carburetor modification, engine horsepower will decrease about

3.5 % for each 1,000-foot (300-meter) increase in altitude. The effect of

altitude on horsepower will be greater than this if no carburetor modification
is made.

NOTICE

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

TECHNICAL AND CONSUMER INFORMATION

Oxygenated Fuels

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

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

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

The following are the EPA-approved percentages of oxygenates:

ETHANOL ——— (ethyl or grain alcohol) 10% by volume.

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

MTBE ————— (Methyl Tertiary Butyl Ether) 15% by volume.

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

METHANOL —— (methyl or wood alcohol) 5% by volume.

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

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

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

71

TECHNICAL AND CONSUMER 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 lean carburetor settings and other systems to reduce the
emissions of carbon monoxide, oxides of nitrogen, and hydrocarbons.

The U.S. and California 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.

72

TECHNICAL AND CONSUMER 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. We recom­mend the use of genuine Honda parts whenever you have maintenance done.
These original-design replacement parts are manufactured to the same
standards as the original parts, so you can be confident of their performance.
The use of replacement parts that are not of the original design and quality may
impair the effectiveness of your emission control system.

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

Maintenance

Follow the maintenance schedule on page 43. 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.

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.

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 Honda outboard engine. In California, new outboard engines must be designed,
built and equipped to meet California’s stringent anti-smog emission standards in addition to the U.S. EPA emissions
standards.

Other States

In other areas of the United States your outboard engine must be designed, built and equipped to meet the U.S. EPA
Emission Standard for spark ignited marine engines.

All States

American Honda Motor Co., Inc. must warranty the emission control system on your outboard engine for the period of
time listed below provided there has been no abuse, neglect or improper maintenance of your outboard engine. Where
a warranty condition exists, American Honda Motor Co., Inc. will repair your outboard engine at no cost to you including
diagnosis, parts and labor. Your emission control system may include such parts as the carburetor or fuel injection
system and catalytic converter. Also included may be hoses, connectors and other emission-related assemblies.

MANUFACTURER’S EMISSION CONTROL SYSTEM WARRANTY COVERAGE:

The 2001 and later outboard engines are warranted for four years or 250 hours of operation, whichever comes
first. However, warranty coverage based on the hourly period is only permitted for outboard engines equipped with
appropriate hour meters. If any emission-related part on your outboard engine is defective under warranty, the part
will be repaired or replaced by American Honda Motor Co., Inc.

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

WARRANTY COVERAGE:

Honda outboard engines manufactured after June 1, 2000 are covered by this warranty for a period of four years or
250 operating hours, whichever comes first, 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 87. 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 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 your 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.
