OSE Suggests 20,000-35,000 total rpm for boats. We suggest most Fast Electric Boaters should run in the 25,000RPM range for Sport Boating or 30,000RPM Range for racing. These are only guidelines, we suggest if you do not have the knowledge to pick the correct motor, please consult us first or other members of the rc fast electric boating community.
