WARNING
EWM01570
●
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.
EMU33580
Remote control requirements
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.
WARNING
EWM01580
● 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.

Battery requirement
CAUTION:
ECM01061
Do not use a battery that does not meet
the specified capacity. If a battery that
does not meet specifications is used, the
electric system could perform poorly or
be overloaded, causing electric system
damage.
For electric start models, choose a battery
which meets the following specifications.
EMU25721
Battery specifications
The engine cannot be started if battery volt-
age is too low.
EMU25730
Without a rectifier or Rectifier Regulator
CAUTION:
ECM01090
A battery cannot be connected to models
that do not have a rectifier or Rectifier
Regulator.
If you wish to use a battery with the models
without a rectifier or Rectifier Regulator, in-
stall an optional Rectifier Regulator.
Using a maintenance-free battery with the
above models can shorten the life of the bat-
tery significantly.
Install an optional Rectifier Regulator or use
accessories rated to withstand 18 volts or
higher with the above models. Consult your
Yamaha dealer for details on installing an
optional Rectifier Regulator.

Propeller selection
Next to selecting an outboard, choosing the
right propeller is one of the most important
purchasing decisions a boater can make.
The type, size, and design of your propeller
have a direct impact on acceleration, top
speed, fuel economy, and even engine life.
Yamaha designs and manufactures propel-
lers for every Yamaha outboard motor and
every application.
Your outboard motor came with a Yamaha
propeller chosen to perform well over a
range of applications, but there may be uses
