Which shaft length do I need?

The shaft length must match the transom height of your boat: the height of the transom, measured from the top to the bottom of the hull.

  1. 1

    Measure your transom

    Measure the transom height in the middle of the transom, straight down to the bottom of the hull.

  2. 2

    Compare with the engine

    For each shaft length the manufacturer states which transom height it is meant for. Choose the shaft that matches.

  3. 3

    Too short or too long?

    Too short: the propeller draws in air and cooling works poorly. Too long: more drag and less speed. In doubt, ask the builder or a dealer.
