PROPELLER SELECTION
The performance of your outboard motor will
be critically affected by your choice of pro-
peller,
as
an
incorrect
choice
could
adversely affect 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 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 operat-
ing load, a smaller-pitch propeller is more
suitable as it enables the correct engine
speed to be maintained. 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
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 “SPECIFICATIONS” on page 4-1.
Select a propeller which fulfills this require-
ment.
If operating under conditions which allow the
engine’s rpm to rise above the maximum rec-
ommended range (such as light boat loads),
reduce the throttle setting to maintain the
rpm in the proper operating range.
