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.
An accurate propeller reduces the level of cavitation.

A Compu Prop accurate propeller serves you better and has a longer life.
