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 following
procedures.

NOTICE
To prevent problems which can be

caused by oil entering the cylinder from
the sump, keep the outboard motor in
the attitude shown when transporting
and storing it. If storing or transporting
the outboard motor on its side (not up-
right), put it on a cushion after draining
the engine oil.
Do not place the outboard motor on its
G
side before the cooling water has
drained from it completely, otherwise
water may enter the cylinder through the
exhaust port and cause engine trouble.
Store the outboard motor in a dry, well-
G
ventilated place, not in direct sunlight.
