Counter rotation models

Standard outboard motors rotate clockwise.
Counter rotation models rotate counterclock-
wise. Counter rotation models are typically
used in multiple motor setups and are marked
with an "L" on the gear case above the anti-
ventilation plate.
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 70 and 71.

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 before
starting the engine.
