I think the hull is slightly different on the older ones,more wieght and different X dimension than the newer ICC's.

OK- The reason i ask is by the numbers reported it seems theres a -10 mph difference in top speed ?
Is this right ?

My 06 496 28 ICC will run over 100mph anyday
Just curious

I'm pretty sure Eliminator changed the bottoms very slighlty on the ICC's. A lot of how any of them run is how they are set-up...I do believe the new hulls are slightly faster though...IE, a few mph...

What props and drives are you using?

I thought the steps were smaller on the new ones and they seem to be about 10 mph faster.

maybe shueman can chime in and clear this up

X-Dimension and weight plays a huge difference in the speed differences.
A 1999 tall deck 28 took roughly 500hp per side to run 100.
A 2005 ICC took roughly 425hp per side to do it.

Can you provide a few more details? Is this a carbon fiber layup? Full cabin? what drive ratio's props etc..

Standard layup , B1 Drives no boxes - imco shorties w/ bravo 30p

Looks about right...I talked to Tony and a 28' ICC is 15-20mph faster, with the same power setup. The Tall Deck performs much better in rough water though...:cool:
