Mounting motor
WARNING

● Improper mounting of the outboard mo-
tor could result in hazardous conditions
such as poor handling, loss of control,
or fire hazards.
● Because the motor is very heavy, spe-
cial equipment and training is required
to mount it safely.
Your dealer or other person experienced in
proper rigging should mount the motor using
correct equipment and complete rigging in-
structions. For further information, see page
28.

Remote control requirements
WARNING

● If the engine starts in gear, the boat can
move suddenly and unexpectedly, pos-

start-in-gear protection device is not
working correctly and you should dis-
continue using the outboard. Contact
your Yamaha dealer.
The remote control unit must be equipped
with a start-in-gear protection device(s). This
device prevents the engine from starting un-
less it is in neutral.
