Storing outboard motor

When storing your Yamaha outboard motor
for prolonged periods of time (2 months or
longer), several important procedures must
be performed to prevent excessive damage.
It is advisable to have your outboard motor
serviced by an authorized Yamaha dealer pri-
or to storage. However, you, the owner, with
a minimum of tools, can perform the follow-
ing procedures.

side before the cooling water has

NOTICE
Before starting the engine, make sure to
supply water to the cooling water passag-
es. Otherwise, the engine could overheat
and be damaged.
Cooling system flushing is essential to pre-
vent the cooling system from clogging up
with salt, sand, or dirt. In addition, fogging/lu-
bricating of the engine is mandatory to pre-
vent excessive engine damage due to rust.
Perform the flushing and fogging at the same
time.
1. Wash the outboard motor body using
fresh water. For further information, see
page 34.
2. Place the fuel cock in the closed posi-
