It sounds like your you are talking about the Parvey's 43 BT GT. Seen this boat first hand and it is very impressive having all the amentities and running the speed it does. This is not your average BT so I personnally would not use this boat as comparison when talking BT speeds. From what I have seen it is going to take roughly 1000 HP and #6's or equivalent to make a BT run near 100 MPH. A staggered set up will help.

Sunny F-4 with 700's/NXT's.

I've got a 16' padvee outboard with a ported 2.4 that will run a hair over 100. If you throw in a porta john, a coleman stove, small fridge and a microwave, it will probably knock 6 mph off of it. I'll sell it cheap.

Don't be greedy just go 80
