WARNING

 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.
 Leaking fuel is a fire hazard. When
transporting and storing the outboard
motor, disconnect the fuel line from the
outboard motor to prevent fuel from
leaking.
 Never get under the outboard motor
while it is tilted. Severe injury could oc-
cur if the outboard motor accidentally
falls.
 Do not use the tilt support lever or knob
when trailering the boat. The outboard
motor could shake loose from the tilt
support and fall. If the outboard motor
cannot be trailered in the normal run-
ning position, use an additional sup-
port device to secure it in the tilt
position.
When storing or transporting the outboard
motor, make sure to follow the procedure list-
ed below.
 Disconnect the fuel hose from the fuel joint
on the outboard motor and install the fuel
joint cap.
 Tighten the fuel tank cap and its air vent
screw.
 Store the fuel tank in a well-ventilated
place.
 Store the fuel tank in a place that is stable
and not exposed to shocks.
When the outboard motor is tilted prolonged
time for mooring or trailering the boat, make
sure to follow the procedure listed below.
 Disconnect the fuel hose from the fuel joint
on the outboard motor and install the fuel
joint cap.
 Tighten the fuel tank cap and its air vent
screw.
The outboard motor should be transported
and stored in the normal running position. If
there is insufficient road clearance in this po-
sition, then trailer the outboard motor in the
tilt position 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.
