Could be, as the engine was not dynoed. I think my problem is prop slip though. I had a good run yesterday with the same old 28p Hydromotive 3 blade as the Bravo 4 blade hasn't arrived yet. Ran 78 GPS @ 5,400 rpm bumping the limiter again, 3 people 1/2 fuel, trimmed 1/2 out. I calculate that as 18.3% prop slip, which is a lot.
I have to admit, at that speed it's a bit of a handful and I'm starting to think about hydraulic dual ram steering. Carl, you the same XR/IMCO setup, what steering do you have?
