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

1. Wash the outside of the outboard motor with clean, fresh water.
2. Remove the flush bolt.
3. Flush the cooling system, using the hose coupler (optional).
a. Attach a hose from a fresh water faucet to the hose coupler.
b. Remove the propeller.
c. Turn on the fresh water supply to the hose.
d. Start the engine and run in neutral for at least 5 minutes.
(Without

1. Wash the outside of the outbnoard
motor with clean, fresh water.
2. Remove the propeller.
3. Stand the motor i,n a suitable container of water. The water level must be
at least 4 inches above the anti-cavitaiton
plate.
4. Start the engine and run slowly for at least 5 minutes.

CAUTION:
l
Running the engine without

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. 361, drain the contents of the
carburetor into a suitable container, then retighten the drain screw.
3. Change the engine oil (p. 27) 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 plug. While pressing the engine stop button, pull the
recoil starter several times to completely
expel water from the cylinder.
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.
i 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 the spark plug hole, then pull the’ recoil
starter several times to lubricate the inside of the cylinder. Reinstall the
spark plug.
6. Attempt to start the engine.
l
If the engine fails to start, remove the spark plug
clean and dry the
electrodes, then reinstall the spark plug 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
insoection and service.
