Yamaha outboard motors are fitted with
propellers 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 pro-
peller is more suitable for a smaller oper-
ating load.
Yamaha dealers stock a range of pro-
pellers, and can advise you and install a
propeller on your outboard that is best
suited to your application.
NOTE:
At full throttle and under a maximum
boat load, the engine's rpm should be
within the upper half of the full throttle
operating range, as listed in "SPECIFICA-
TIONS" on page 4-1. Select a propeller
which fulfills this requirement.
If operating under conditions which allow
13 x 17 - K
the engine's rpm to rise above the maxi-
q w e
mum recommended range (such as light
boat loads), reduce the throttle setting to
maintain the rpm in the proper operating
range.
