Counter rotation models

Standard outboard motors rotate clockwise.
Counter rotation models rotate counterclock-
wise and are typically used in multiple motor
setups.
On counter rotation models, be sure to use a
propeller intended for counterclockwise rota-
tion. These propellers are identified with the
letter "L" after the size indication on the pro-
peller. WARNING! Never use a standard
propeller with a counter rotation motor, or
a counter rotation propeller with a stan-
dard motor. Otherwise the boat could go
in the direction opposite of that expected
(for example, reverse instead of forward),
which could lead to an accident.
For instructions on propeller removal and in-
stallation, see page 94.

Start-in-gear protection

Yamaha outboard motors or Yamaha-ap-
proved remote control units are equipped
with start-in-gear protection device(s). This
feature permits the engine to be started only
when it is in neutral. Always select neutral be-
fore starting the engine.
