Engine
1. Wash the engine exterior and flush the
cooling water system thoroughly with
fresh water. Drain the water com-
pletely.
Wipe off any surface water with an oily
rag.
2. Use a dry cloth to completely wipe off
water and salt from the electrical com-
ponents.
3. Drain all fuel from the fuel hoses, fuel
pump, and carburetor, and 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 spray
storage oil (available from an autho-
rized dealer) into the combustion
chamber through the spark plug holes
while slowly turning the motor over
using the recoil starter.
5. Change the engine oil.
6. Change the gear oil in the gear case.
7. Apply grease to the propeller shaft.
8. Apply grease to all sliding parts, joints,
nuts, and bolts.
9. Stand the outboard motor up vertically
in a dry place.
