The Benefits of

Cavitation Reduction

Cavitation is caused by water vaporizing due to pressure reduction on the propeller blades. This can be caused by mechanical damage such as bent or impacted blades, wrongly matched power to propeller type or incorrect propeller design. This distortion of the flow pattern can significantly reduce power and efficiency and cause erosion of the rotating propeller blades.
Prop Scan reduces the level of propeller cavitation which result in improved efficiency and extended propeller life.

Eliminate Propeller Induced Vibration

  • Vibration is annoying
  • Vibration absorbs power
  • Vibration increases engine wear
  • Vibration can cause blade failure
  • Vibration slowly destroys your boat

Inaccuracies in marine propellers, such as variations in pitch and camber, cause your propeller to vibrate. With the use of Prop Scan these inaccuracies are removed. Prop Scan detects even the most minor variations (it measures down to 0.004"). Using Prop Scan technology, propeller induced vibrations are eliminated, making your vessel smooth, quiet and economical.

Consume Less Fuel

Prop Scan optimized boat propellers are accurate and efficient. Vessels with Prop Scan optimized propellers consume less fuel, saving money and increasing a vessels range. On average, a vessel with a ISO Class S propeller uses between 10 - 15% less fuel than a Class III propeller.

ISO Compliance

The ISO 484/2 standards and Prop Scan EPS (enhanced propeller standard) make propeller measurements reliable and comparable.

Higher Speed

  • Increased top speed
  • Increased cruising speed
  • Increased power

By precisely optimizing a propeller using Prop Scan, a vessels performance can be increased. After the Prop Scan propeller optimization process, many customers have found their top speed has increased by 2 - 3 knots. Some customers have even experienced increases of 5 - 6 knots!
