Boat horsepower rating
WARNING
EWM01561
Overpowering a boat can cause severe
instability.
Before installing the outboard motor(s), con-
firm that the total horsepower of your out-
board motor(s) does not exceed the boats
maximum horsepower rating. See the boat’s
capacity plate or contact the manufacturer.
EMU33572
Mounting motor
WARNING
EWM01571
Improper mounting of the outboard mo-
tor could result in hazardous condi-
tions 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
31.
EMU33582
Remote control requirements
WARNING
EWM01581
If the engine starts in gear, the boat can
move suddenly and unexpectedly, pos-
sibly causing a collision or throwing
passengers overboard.
If the engine ever starts in gear, the
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.
