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.

Dismounting the outboard motor
1. Stop the engine and land the boat.
2. Disconnect the fuel line from the out-
board motor.
3. For electric start models, disconnect the
battery cables from the battery termi-
nals.
4. To prevent steering movement, turn the
adjuster lever to “A”.
5. Loosen the clamp screw(s).
6. Hold the handgrips and steering brack-
ets as shown in the illustration and lift up
the outboard motor to dismount it from
the boat.
