No. Boat length is only a rough clue. Engine output, reduction ratio, hull shape, displacement, aperture clearance, and current RPM under load are what make the propeller fit correctly. Why is pitch not listed as a simple dropdown? Pitch is part of the configured quote. A propeller with the right diameter but wrong pitch can overload the engine or fail to use the available power. What should I send if I am not sure? Send the boat and engine data above plus photos of the existing propeller, shaft or saildrive, and any markings on the hub. That is enough to avoid most sizing mistakes.
