checked fountains web site. only has 42 w/575's. says 86+

Re: new 42 w/bravo xr's-how much hp
 

just buy fountaindriver's 42 and be done with it 130mph+

Re: new 42 w/bravo xr's-how much hp
 

I would think 800hp is the range. XR may be a problem. Go with staggered for sure.

Pair-a-dice 2000 with 900sc (850hp) light lay-up, full cabin did 117mph.

Sounds like my next boat if there is one!

sorry to hear, just nosey. Did you try Boat Trader, Yacht trader? There was a thread on the best medium for advertising just recently.
Mike Livorsi told me once that yacht trader was the best he thought.
