NOTE:
Select a propeller which will allow the engine
to reach the middle or upper half of the oper-
ating range at full throttle with the maximum
boat load. If operating conditions such as light
boat loads then allow the engine r/min to rise
above the maximum recommended range, re-
duce the throttle setting to maintain the en-
gine in the proper operating range.

Propeller selection
The performance of your outboard motor will
be critically affected by your choice of propel-
ler, as an incorrect choice could adversely af-
fect performance and could also seriously
damage the motor. Engine speed depends on
the propeller size and boat load. If engine
speed is too high or too low for good engine For instructions on propeller removal and in-
performance, this will have an adverse effect stallation, see page 56.

Start-in-gear protection
Yamaha outboard motors are fitted with pro-
pellers chosen to perform well over a range of
applications, but there may be uses where a
propeller with a different pitch would be more
appropriate. For a greater operating load, a
smaller-pitch propeller is more suitable as it
enables the correct engine speed to be main-
tained. Conversely, a larger-pitch propeller is
more suitable for a smaller operating load.
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.
