...Why did you need to change out an engine after 3 years? ...

The engine builder couldn't get it right.  We went through 3 internal engine failures in 2-½ years.  Luckily, all under warranty.

Needless to say, we don't recommend them any more!

Well its been a while since I updated. I ended up rebuilding the drive I had. Now that its broke in I was able to test a prop I bought. It was a 28P 4 blade Trophy Plus. 

I got up on plane pretty easy but I dropped down to about 4500 rpm at WOT and only about 62MPH. I did have 3 people and a full tank. I am guessing that only made a 2 or so MPH difference though. So 28P is too much I would like to find a 26 or 27P Bravo prop to try. I have spoke with a few prop guys and that is what they are recommending to try. Now I just have to find one.

Still my best run was on the 26P Hydromotive intimidator 4 blade at 5600 rpm and 68.4 MPH
I think this has become an addiction.
