Suzuki RPM Guide

Please use the RPM Guide to help determine the correct maximum revs for your engine. The right size propeller should load your motor between the correct wide open throttle RPM listed for your horsepower.

Every outboard and sterndrive motor has a WOT rating, as established by the manufacturer. The WOT rating is the RPM range the motor should achieve when running at wide open throttle. If the propeller has too much pitch, the motor will not reach its optimum RPM at WOT, while a prop with too little pitch will exceed the recommended RPM limit at WOT.
