Calculations

Calculator results are estimates worked out from the numbers you enter. Hulls, loads, props and water conditions differ, so check a result on the water with a GPS and a tachometer before relying on it.

Parts and specifications

Engine specifications and part details here come from manufacturers' published documents. Makers revise their products, so a detail can be out of date.

Safety

Disconnect the battery before working on boat wiring. A short on a battery cable can start a fire.

Gasoline vapor is explosive. Work on fuel systems in open air, away from sparks and flames.

Trailer bearings, brakes, lights and tires all affect safety on the road. Check them before you tow.

Wear a life jacket, and follow the U.S. Coast Guard and your state's boating rules.
