Transporting and storing
outboard motor
WARNING
EWM00690
●
Leaking fuel is a fire hazard. When
transporting and storing the outboard
motor, close the air vent screw and fuel
cock to prevent fuel from leaking.
●
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
EWM00700
Never get under the lower unit while it is
tilted, even if a motor support bar is used.
Severe injury could occur if the outboard
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.
EMU30272
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:
ECM01411
●
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.
