His was a 350 Mag and I believe it put out 270 hp. I am not sure of the prop he ran but I used a 22" Turbo prop and topped out at 52 MPH and he would inch away from me at top end but I always got him out of the whole and then he would eventually catch me.

Great info J.B. I bought this boat at auction so I haven't had a chance to try it out yet. As you can see from the pics it has a four blade prop on it which I believe has a 19" pitch (numbers inside of hub end with -19). I have fired it in the driveway on muffs and everything seems to be working, I want to go over it really well before I test it. I am hoping to hit 60MPH (probably not with the current prop).
