Yep, one type of cavitation. It can also be caused by poor prop selection, poor trim on an o or I/O, wrong prop for weight etc. My 40 hp Honda will cavitate at top end when empty. The prop is designed to move three guys, two dogs a layout boat and 150 decoys so it "cuts" more. I am no expert but the Board boat is not designed to yank & bank empty. Just add a little weight to keep the prop in the water.

I think porposing is also a form of cavitation.

Where the heck is Brian, he would know better than I would.

Ha I see Brian is still at work - what is your $.02 at this late hours? I will find out tomorrow
