General information
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
performance, this will have an adverse effect
on the engine.
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 dealers stock a range of propellers,
and can advise you and install a propeller on
your outboard that is best suited to your appli-
cation.

Propeller selection
The performance of your outboard motor will
be critically affected by your choice of propel-
