Extension Boxes
I have read all the posts but can not seem to find what the outcome was?
Was their any positives to the 12" extension?
Did it required changing the X dimension?
Did it gain any speed?
What did it do for rough water handeling?
Again, I have a 24' without steps or a notch.
Just trying to figure out what all my options are.

Re: Extension Boxes
Razor,
I don't know of anyone that has put an extension box on a 24' Superboat.
On the 30' Supers, it was a plus for the Zuperboat but a minus for Jcap's boat.
I had though about adding one until I learnd that my external steering rams were too long.
I would bet that a 12" neutral extension box with a 2" short drive would be a possitive on a 24' Super. I beleive it would improve the rough water handling because it would lengthen the boat a bit. And the prop would be move to "cleaner" water so the boat would likely be a bit faster.
It is an expensive proposistion though...
Full hydraulic twim ram steering, extention box & drive line mods, and a short lower drive unit.

Re: Extension Boxes
What would I have to modify on the drive lines? I figured I would ask. If I am making the switch to hydraulic steering, I thought this looked like a really nice setup. I have not looked into the cost yet.
If I installed a 2" short drive, wouldn't it be hard to get the bow up?
I have the happit of making changes and not doing it the way I should have in the first place, and paying a lot more for the finished product.

If you use a Stellings box, the coupler on the engine changes and also the shaft from the drive.
I don't think there would be a problem carrying the bow with a 12" extension box and short drive, the drive on the 24s is pretty low to start. With an extension a short drive is the norm; swapping the drive lower is the easy part.

Re: Extension Boxes
RAZOR Imco stuff is nice and was on my boat when I bought it. I really think it made my boat run like it did. If you get 2-3 mph out of the box and short drive that will be alot. Call imco and get prices but make sure your sitting down. Jeff from JC performance has an old 24 running 100 with the drive very high no box and no notch. Has big power and a herring 6 blade. Best bang for the buck is to come to my house with 6k, bolt it into your 24 and my guess is 85-90 mph.

Did Oh Zone run the boat without the ITS? I would like to hear before and after comparisons

The numbers from the shoot out with Activator would indicate that Oh-Zone's boat runs about the same as JCjrs old boat with the same power and no extension box.
That ITS system is a real nice clean package though...

Re: Extension Boxes
I have yet to see any performance gains. I did raise the X 1" so the center of the bullet is 2 3/4" below the lowest part of the hull. Mine had ITS from the get go..... I did the ITS for the clean transome. No seperate steering rams...
