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
prior to storage. However, you, the owner,
with a minimum of tools, can perform the fol-
lowing procedures.

CAUTION:
To prevent problems which can be
G
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 trou-
ble.
Store the outboard motor in a dry, well-
G
ventilated place, not in direct sunlight.

Flushing in a test tank

boat. For further details, see page 56.

other qualified mechanic if the fuel system is
to be drained instead.

board motor.
