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.
To check the propeller, see page 61.
