Prop - Pro-Line Boats 2000 30 Sport Owner's Manual

Prop

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 desired performance needs. For instance:
* Decreasing pitch will enhance acceleration and power at high loads.
* Increasing pitch will increase speed at light loads.
* Decreasing diameter will compensate for loss of power at high altitudes.
* Increasing 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.
