Boat handles great...still gets on plane easy as far as speed...I got 17mph out of it.
Talk to at Fountain...I guess one of the tech boys.

17 MPH? Was that increase from the boxes and shorties or in conjunction with an engine upgrade?

Martin Sanborn.
He gave me some good insight on Fountains and boxes.

Oh yeah I went from 525Sc's to 800Sc's with the boxes and drives...

I talked to Martin @ Fountain and have decided not to do boxes or shortie drives. I am going to blueprint the bottom and change the transom cut-out. I am going to wait until late in the season and do it then. We are talking about raising the drives 1".

you could just bolt up a -1" lower...

I need to do some bottom work and my transom assemblies need to be removed to be refinished and will be replacing engines at the end of the season so it will actually be cheaper to raise the drives than to buy 2 shorties.
