according to my calculations its about 100hp off....or better yet...i should be doing almost 110mph

it takes a lot more then 100hp to go from 100mph to 107mph

According to what my last boat did it is about 230hp off. And i guarantee the new boat will be at least 15-20 mph faster with the exact same motor in it.

The Jet being "Right" and "tight " is critcal , but Horse power , "set up" and "tune up" will bring you speed  Tom

I'm confused. you were hitting 53 or 75?

53 with your set up, yeah, I'd go after the pump. 75? leave the focker alone!!! you're doing more than fine!

I don't understand.  You know you want to go faster...  But you still haven't even pushed it to W.O.T. to see where you're at?   :D
