Propellers

If your Pro-Line was ordered with a factory installed engine, it will have a propeller that has been
performance tested to provide the best all-round performance for your engine/hull combination at sea
level. In some situations, it may be desirable to re-prop your Pro-Line to enhance the desired
performance needs for your area. For instance:
•
Decreasing the pitch will enhance acceleration and power at high loads.
•
Increasing the pitch will increase speed at light loads.
•
Decreasing the diameter will compensate for any loss of power at high altitudes.
•
Increasing the diameter results in higher efficiency at low speeds at the expense of top
end speed and acceleration.
Be sure not to over rev the engine when re-propping or engine damage could result. Operating your
engine with a damaged prop will decrease performance, increase fuel consumption, and may introduce
undesirable handling characteristics. The vibration caused by running a damaged prop could cause
costly damage to your lower drive unit.
