Propeller selection

Next to selecting an outboard, choosing the
right propeller is one of the most important
purchasing decisions a boater can make. The
type, size, and design of your propeller have
Basic requirements
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 outboard motor came with a Yamaha
propeller chosen to perform well over a range
of applications, but there may be uses where
a different propeller would be more appropri-
ate.
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, chose 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, chose 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.
For instructions on propeller removal and in-
stallation, see page 70.
