2. Fuel Level
Check the fuel gauge

and refill the tank if.the

fuel level is low.

NOTE: Open the vent knob b’efore removing the fuel filler cap. When the
vent knob is firmly clbsed, the cap will be difficult
to remove.
Your engine
is designed
to use any gasoline
that has a pump octane number lR + M, of 86 or higher, or that has a research octane number
of 91 or higher.* Gasoline pumps at service station normally display the
pump octane number.
We recommend
that you use unleaded fuel because it produces
fewer
engine and spark plug deposits
and extends the life of exhaust system
components.
Never use stale or contaminated
gasoline or an oil/gasoline
mixture. Avoid
getting dirt, dust or water in the fuel tank. Use of a lower octane gasoline
can cause persistent
“pinging”
or heavy “spark knock” (a metallic rapping
noise) which, if severe, can lead to engine damage.
CAUTION:
If “spark knock” or “pinging”
occurs at a steady engine speed
under normal load, change brands of gasoline. If spark knock or pinging
persists,
consult your authorized
Honda dealer. Failure to do so is considered misuse, and damage caused by misuse is not covered by Honda’s
Limited Warranty.
Occasionally
you may experience
light spark knock while operating
under
heavy loads. This is no cause for concern, it simply means your engine is
operating
efficiently.

Do not overfill the tank (there should be no fuel in the filler neck). After
refueling,
make sure the tank cap is closed properly and securely.

GASOLINES

CONTAINING

ALCOHOL

If you decide to use a gasoline containing
alcohol (gasohol), be sure it’s octane rating is at least as high as that recommended
by Honda. There are
one containing
ethanol, and the other containing
two types of “gasohol”:
methanol.
Do not use gasohol that contains more than 10% ethanol. Do
not use gasoline containing
methanol (methyl or wood alcohol) that does
not also contain cosolvents
and corrosion
inhibitors
for methanol.
Never
use gasoline containing
more than 5% methanol,
even if it has cosolvents
and corrosion inhibitors.
NOTE:
l
Fuel system damage or engine performance
problems resulting from the
use of fuels that contain alcohol is not covered under the warranty.
Honda cannot endorse the use pf fuels containing
methanol
since
evidence of their suitability
is as yet incomplete.
l
Before buying fuel from an unfamiliar station, try to find out the fuel contains alcohol, if it does, confirm the type and percentage
of alcohol used. If you notice any undesirable
operating
symptoms
while using a
gasoline that contains alcohol, or one that you think contains alcohol,
switch to a gasoline that you know does not contain alcohol.

5. High altitude

operation

At high altitude, the standard carburetor air-fuel mixture will be excessively
rich. performance
will decrease, and fuel consumption
will increase.
High altitude performance
can be improved by installing a smaller diameter
main fuel jet in the carburetor and readjusting the pilot screw. If you always
operate the outboard motor at altitudes higher than 6,000 feet above sea
level, have your authorized
Honda Outboard
Motor dealer perform these
carburetor
modifications.
Even with suitable carburetor jetting, engine horsepower
will decrease approximately
3.5% for each 1,000 foot increase in altitude. The affect of
altitude on horsepower
will be greater than this if no carburetor
modification is made.
CAUTION:
Operation
of the outboard motor at an altitu,de lower than the
carburetor
is jetted for may result in reduced performance,
overheating,
and serious engine damage caused by an excessively
lean air/fuel mixture.

Gear Oil Check/Change
Oil Level Check
Check the oil level when the engine is in the vertical position. Remove the
level screw and see if oil flows out. If no oil comes out, fill through the drain
scerw hole until the oil starts to flow out through the level screw hole. If
there is water in the oil, the water will flow out first when the drain screw is
removed, or the oil will be a milky color.
Oil Change
Remove the level screw and drain screw to drain the oil. Inject oil through
the drain screw hole until it starts flowing out through the level screw hole.
Reinstall and tighten the level screw and drain screw securely.

Servicing

a Submerged

Motor

A submerged
motor must be serviced immediately
after it. is recovered
from the water in order to minimize corrosion.
If there is a Honda outboard motor dealership nearby, take the motor immediately to the dealer. If you are far from a dealership, proceed as follows:
1. Remove the engine cover, and rinse the motor with fresh water to
remove salt water, sand, mud, etc.
2. Loosen the carburetor drain screw (p. 421, drain the contents of the carburetor into a suitable container,
then retighten the drain screw.
3. Change the engine oil (p. 30). If there was water in the engine
crankcase, or the used engine oil showed signs of water contamination,
then a second engine oil change should be performed after running the
engine for l/2 hour.
4. Remove the spark plugs. While pressing the engine stop button, pull the
recoil starter several times to completely
expel water from the cylinders.
CAUTION:
l
When cranking
the engine with an open ignition circuit (spark plugs
removed from the ignition circuit), keep the engine stop button depressed to prevent electrical damage to the ignition system.
l
If the motor 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 motor until it has been repaired.
5. Pour a teaspoon of engine oil into each spark plug hole, then pull the
recoil starter several times to lubricate
the inside of the cylinders.
Reinstall the spark plugs.
6. Attempt to start the engine.
l
If the engine fails to start, remove the spark plugs, clean and dry the
electrodes,
then reinstall the spark plugs and attempt to start the
engine again.
l
If the engine starts, and no mechanical
damage is evident, continue
to run the engine for l/2 hour or longer (be sure the water level is at
least 4 inches above the cavitation
plate).
7. As soon as possible, take the motor to a Honda outboard motor dealer
for inspection
and service.
