OSE suggests 20,000-35,000 total rpm for boats. We suggest that most Fast Electric Boaters should run in the 25,000 RPM range for sport boating or the 30,000 RPM range for racing. These are only guidelines; if you don't know how to choose the correct motor, please consult other members of the RC fast electric boating community or us either at a local club or on our OSE Forums.
