Your outboard motor came with a Yamaha
propeller chosen to perform well over a range
of applications, but there may be uses where
a different propeller would be more appropri-
ate.
Your Yamaha dealer can help you select the
right propeller for your boating needs. Select
a propeller that will allow the engine to reach
the middle or upper half of the operating
range at full throttle with the maximum boat-
load. Generally, chose a larger pitch propeller
for a smaller operating load and a smaller
pitch propeller for a heavier load. If you carry
loads that vary widely, chose the propeller
that lets the engine run in the proper range for
your maximum load but remember that you
may need to reduce your throttle setting to
stay within the recommended engine speed
range when carrying lighter loads.
For instructions on propeller removal and in-
stallation, see page 74.

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.
Specifications and requirements
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 75 and 75.

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.
