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.
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
Specifications and requirements
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.
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, select a larger pitch propel-
ler for a smaller operating load and a smaller
pitch propeller for a heavier load. If you carry
loads that vary widely, select 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.
To check the propeller, see page 75.
