Cavitation issue

seahunt202

i have a 25’ avanti whoxh is pretty much the same as the older bracketed Sea Vee with twin 150 Yamaha. I can’t fI gure out why I’m having cavitation issues around 18-20 mph. The hieght seems about right which is two inches about the angle (they say your allowed 1” high per length of bracket). I’ve ran mercury mirage props and now some people’s that came off a contender with the same results. Any ideas before throwing a bunch of money at it.

Call Ken at propgods.com, solving prop issues is his specialty.

Do you have a transducer, or something else that could be introducing air into the prop?

I took the transducer off to see if that was the issue and same result. I’m going to bring it to mike at morstar tomorrow to have him go through the engines anyways maybe he will have a solution
