Propeller selection
Next to selecting an outboard motor, selecting
the right propeller is one of the most important
purchasing decisions a boater can make. The
type, size, and design of your propeller have
a direct impact on acceleration, top speed,
fuel economy, and even engine life. Yamaha
designs and manufactures propellers for ev-
ery Yamaha outboard motor and every appli-
cation.
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 propeller
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.
Yamaha recommends “Ventless Design For
new 4-stroke VMAX SHO” for your propeller.
For further information, consult your Yamaha
dealer.
To check the propeller, see page 77.

starting the engine.
