transom angle for stable cruising and
maximum power.

Transom angle too large: Incorrect
causes boat to ‘‘squat’’.

Transom angle too small: Incorrect
causes boat to ‘‘bow steer’’.

It is necessary to adjust the transom
angle 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.

When cruising into a high wind,
lower the transom angle slightly to
level the boat and improve stability.
With a tail wind, raise the transom
angle slightly.

Excessive transom angle during
operation can cause propeller
ventilation and overheating.

FUEL RECOMMENDATIONS

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

This 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 stale or contaminated
gasoline or an oil/gasoline mixture.
Avoid getting dirt or water in the fuel
tank.

Occasionally you may hear a light
‘‘spark knock’’ or ‘‘pinging’’
(metallic rapping noise) while
operating under heavy loads. This is
no cause for concern.

If spark knock or pinging occurs at a
steady engine speed, under normal
load, change brands of gasoline. If
spark knock or pinging persists, see
an authorized Honda marine dealer.

Running the engine with persistent
spark knock or pinging can cause
engine damage.

Running the engine with persistent

STORAGE

STORAGE PREPARATION Fuel

Proper storage preparation is
essential for keeping your outboard
motor troublefree 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

Thoroughly clean and flush the
outboard motor with f resh water after
operation in dirty water or salt water.

Wash the outside of the outboard
motor with clean, fresh water to
remove mud, salt, seaweed, etc.

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

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 within a few
months, or even less if the gasoline
was not fresh when you filled the
fuel tank.

Distributor’s Limited Warranty

The
does not cover fuel system damage
or engine performance problems
resulting from neglected storage
preparation.

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.

51

STORAGE

Adding a Fuel Stabilizer Draining the Fuel Tank and

Carburetor

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.

Add fuel stabilizer following the

1.
manufacturer’s instructions.

Refer to previous page for proper

2.
running procedure. After adding a
fuel stabilizer, run the engine
outdoors for 10 minutes to be sure
that the treated gasoline has

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 (300­meter) 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
modif ied f or high altitude operation,
the air-f uel mixture will be too lean
f or 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
f actory specif ications.

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:

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:

15% by volume.

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

METHANOL:

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

ethyl or grain alcohol;

Methyl Tertiary Butyl Ether;

methyl or wood

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.

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.

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 AlteringThe U.S. and Calif ornia Clean

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.

65

TECHNICAL AND CONSUMER INFORMATION

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 PartsProblems That May Aff ect

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
p. . Remember that this schedule

39
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.
