A damaged prop can also cause cavitation which you will feel in the form of vibration.

Pontoon boat motor cavitation. Also are add-on cavitation plates useful on pontoon motors to reduce prop ventilation issues. All it takes is a little wave action or loading heavy and the problem gets worse. Standard props are pitched too steep for the slow speeds 20-25mph at full throttleand they run on the edge of cavitation.

Is 16 the transom mount on the motor to the prop center-line is 23. It has a top speed of approximately 36 mph at 5600 rpm or so with 4 person load. Even slightly chipped or bent blade edges can cause surrounding water to BOIL cavitate.

Any owner seeking the last bit of speed from an outboard-powered boat should grab a yard stick. Cavitation plates are mounted to the lower units of boats to help increase performance. Secondly it causes those vibrations which makes your ride less comfortable.

Cavitation wastes energy makes the propeller noisy as the vapor bubbles collapse and most seriously erodes the props surface due to localized shock waves against the blade surface. My only complaint is the cavitation issue I experienced a couple times. Its a plague of pontoon boats and why merc invented Big Foot motors.

They can also be caused by improper geometry or upstream imperfections related to the hull such as hull design and configuration hull imperfection incorrectly installed accessoriesappendages etc. Water disturbance from the pontoons can also cause it on some toons. Do you know the difference between cavitation and ventilation.

Cavitation is bad for three reasons. Propeller cavitation Cavitation if the formation of air bubbles on the propeller. First it can physically damage the propeller.
