Yeah all i have to do is measure that everything will fit ok under the hatch. I know this will push my boat into the 80's. The shop that's building it said this platform can get me close to 800hp but I've told him I'd rather stay around 700hp. The Bravo is gonna be screaming for mercy with 700 much alone 800. Ot thing I am kinda curious is what kind of speeds will a 700hp fountain get mid 80's? Doesn't seem like there's many single engine fountains with big hp. Also how are the 29's handling at that speed?

The Rpms are low since we kept the stock rev limiter at 5400. If we changed some stuff around and let the motor go more rpms and builder was confident it be 750hp or more. Boost is only at 5lbs, we planned at going with more boost and aluminum heads to push it up over 800hp, but after everyone's advice on here about the poor bravo one I told me to keep it under 750hp. Those guys at competition marine real now hire stuff.

Well took the boat out for the first time today with new motor. Ran 77mph with a bravo 28p prop at 5400rpms (it was sitting on the rev limiter). Swapped out with a 29p hydro motive prop and couldn't get on plane. Kept blowing the prop out as soon as it would go to roll over. So kinda looking on advice on where to go to next? I heard hydro props run mor pitch then a bravo prop. So I was thinking about maybe trying a 30p bravo prop. We did have 6ppl on board, full cooler, and full of fuel though. So am I headed in the right direction with a 30p bravo? Or should I look at a 27 or 28 hydro?
