Yamaha outboard motors are fitted with propellers 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 operating load, a smaller-pitch propeller is more suitable as it enables the correct engine speed to be main- tained. Conversely, a larger-pitch propeller is more suitable for a smaller operating load.

Yamaha dealers stock a range of pro- pellers, 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 “SPECIFICA- TIONS” on page 4-1. Select a propeller which fulfills this requirement.

If operating under conditions which allow the engine’s rpm to rise above the maximum recommended range (such as light boat loads), reduce the throttle setting to maintain the rpm in the proper operating range.
