Biggest Diameter Wheels you can find eliminated the hop on my 1993 Top Gun when I had the boat. Sky high X dimension 3A's and almost 900HP. No spacers

I spoke with Tfarmer he said the spacers didnt make much difference. He had some kind of hook or wedge put in the bottom(wait I just spend $$ to get rid of one) but at the end of the day it seems it`s just the nature of the beast.

I also remember the wedge thread - can anyone who finds it post up the link? I'll start searching......

And speaking of the wedge, does it work? Does it help the boat fly level? And who does it?

OK, found it:

Well I had a this so called wedge believe in the form of a hook. The ride was better because the boat was plowing thru the water like a tug boat lol
I`ll stick with using tabs for transom lift.

Did you notice the flight attitude change at all?

Meaning before the bottom work "with the hook" it flew level?

and after the bottom work to make it straight or a bit of rocker it flew bow high?

I am probably most interested in this as I do not like how my boat comes out of the water and would like to correct that with the proper setup.
