motor accidentally falls.
CAUTION:
ECM00660
Do not use the tilt support lever or knob
when trailering the boat. The outboard
motor could shake loose from the tilt sup-
port and fall. If the motor cannot be trail-
ered in the normal running position, use
an additional support device to secure it
in the tilt position.
The outboard motor should be trailered and
stored in the normal running position. If there
is insufficient road clearance in this position,
then trailer the outboard motor in the tilt po-
sition using a motor support device such as
a transom saver bar. Consult your Yamaha
dealer for further details.

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
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
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-
ventilated place, not in direct sunlight.
