Propeller Selection

IMPORTANT: Installed propeller must allow engine to run at its

specified maximum wide open throttle revolutions per minute

(rpm). Use an accurate service tachometer to verify engine

operating rpm.

It is the responsibility of the boat manufacturer and/or the selling

dealer to equip the power package with the correct propellers. Refer

to Specifications for engine WOT and operating rpm range.

IMPORTANT: The engines covered in this manual are equipped

with an rpm rev-limiter that is set to an upper (or limited) rpm

amount. This limit is slightly above the normal operating range

of the engine and is designed to help prevent damage from

excessive engine rpm. Once the rpm drops into the

recommended operating rpm range normal engine operation

resumes.

Select a propeller that will allow the engine power package to operate

at or near the top end of the recommended WOT operating rpm

range with a normal load. High rpm, caused by an excessive trim

angle, should not be used in determining correct propeller selection.
