what causes cavitation in a hydro boat .

Could be several things:

1. Prop thrust angle

2. Prop depth

3. Wrong prop

You didn't ID the boat.

byron,,, listen to jerry for sure,, hey has many ties to aquacraft..

the stock prop should be able to get that hull up on plane fairly easily,, a good foward motion launch is key..

Boy this sounds very fimilar.. Yep that happend to me too. where is your strut settings at? i had to run mine at stock setting /alittle deeper. You want the thrust angle slitely on a down ward angle and not a upward angle. Plus get a Y535 prop too.But I ran on the stock plastic vegas props on my vegas and Miss bud both ran great!

I think I had my stock prop set up to high . I was at about 9/16 " , were in the book it states 1 1/16" down to c / l ?
