Transporting and storing
outboard motor
WARNING
EWM00693
●
USE CARE when transporting fuel tank,
whether in a boat or car.
●
DO NOT fill fuel container to maximum
capacity. Gasoline will expand consid-
erably as it warms up and can build up
pressure in the fuel container. This can
cause fuel leakage and a potential fire
hazard.
WARNING
EWM01860
Leaking fuel is a fire hazard. When trans-
porting and storing the outboard motor,
close the fuel cock to prevent fuel from
leaking. Never get under the engine while
it is tilted. Severe injury could occur if the
outboard motor accidentally falls.
NOTICE
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.

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.
