Installation requirements

Boat horsepower rating

EWM01561
WARNING
Overpowering a boat can cause severe in-
stability.
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.

Mounting outboard motor

EWM02501
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 outboard motor is very
heavy, special equipment and training is
required to mount it safely.
Your dealer or other person experienced in
proper rigging should mount the outboard
motor using correct equipment and complete
rigging instructions. For further information,
see page 28.
EMU33582

Remote control requirements

EWM01581
WARNING
 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.
12
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.

Propeller selection

Next to selecting an outboard motor, select-
ing the right propeller is one of the most im-
portant purchasing decisions a boater can
make. The type, size, and design of your pro-
peller have a direct impact on acceleration,
top speed, fuel economy, and even engine
life. Yamaha designs and manufactures pro-
pellers for every Yamaha outboard motor and
every application.
Your outboard motor came with a Yamaha
propeller selected to perform well over a
range of applications, but there may be uses
where a different propeller would be more
appropriate.
