I'm running 85-87mph with my 450hp Small Blocks and -2 Sportmasters lowers that I have had the skeg cut down to more like a imco lower.
My Prop Shafts are still 3in below the bottom of the boat, I would like to raise them even more, like an inch or two...
That would take -3in Shorties or raise the motor and drives up this winter, then I could use spacers to bring it back down if need be.
I've run these speeds (83-87) for 15 years at the Shootout, and I've made it a goal of mine to get my boat to run 90mph at the Shootout.
Right now I'm running 30p labbed 4 blades, 1.65 gears, 5950rpm, 87mph, with a 15% slip.

I'd like you guys to post your set up so we can compare.
