INSPECTION AND MAINTENANCE

3. Off-season storage

Before you put your outboard motor
in storage, it is a good opportunity to
have it serviced and prepared by your
dealer.
!
Before servicing the motor for storage:
• Remove the battery cables.
• Remove the spark plug caps from
the spark plugs.
• Do not run the motor out of the water.
■ Engine
1 Wash the engine exterior and flush
the cooling water system thoroughly
with fresh water. Drain the water
completely.
Wipe off any surface water with an
oily rag.
2 Use a dry cloth to completely wipe
off water and salt from the electrical
components.
3 Drain all fuel from the fuel hoses,
fuel pump, and carburetor, and
9
clean these parts.
Keep in mind that if gasoline is
kept in the carburetor for a long
time, gum and varnish will develop,
causing the float valve to stick,
restricting the fuel flow.
4 Remove the spark plugs and feed
g e n u i n e e n g i n e o i l o r s t o r a g e
fogging oil in through the spark plug
holes.
The oil will be fed into the crank
case from the air silencer attached
to the carburetors. Turn the engine
�������
over several times while feeding the
oil into it and make sure it is evenly
distributed.
5 Change the gear oil in the gear
case.
6 Apply grease to the propeller shaft.
7 Apply grease to all sliding parts,
joints, nuts, and bolts.
8 S t and th e ou tboard mo tor u p

Be sure to use cloth to remove fuel
remaining in the cowl and dispose of it
in accordance with local fire prevention
and environment protection regulations.
■ Battery
1 Disconnect the battery cables.
2 Wipe off any chemical deposits, dirt,
or grease.
3 Apply grease or vaseline to the
battery terminals.
4 Charge the battery completely
before storing it for the winter.
5 Recharge the battery once a month
to prevent it from discharging and
the electrolyte from deteriorating.
6 Store the battery in a dry place.

Electric Starter Motor
Coat the internal pinion gears and the
shaft of the electric starter motor with
grease.
Do not put grease on the teeth of the
starter pinion or flywheel or increased
wear or damage will occur.
