So you have 2 29 Kryptonite's now?
I rigged one the 2002 for a customer a few years back. We have it back he chipped some gears in the lower. He has become a friend.
When I rigged it I was on the phone with Kirk, owner of Kryptonite performance boats many times We took all his advise and got the customer the 100mph plus he wanted, in a rock solid ride.
After runing his boat I realized it was one of the fastest and most stabil boats in its class. I found one by mistake (looking thru repo reports and auctions) for used boats to sell at the marina. The price was right and I got it.
Now I have it, it is far from as stabil as the one we rigged. So here I am working on why and what I will need to do to get it where it needs to be. If I put a standoff box on the one we rigged I could just copy that design but we did not.
The Imco box does that work with the ITS standoff? That would put the drive out there. I will look into it.
Thanks
Don

I'm by far not an expert on this but, no I don't think the ITS will work with a box. That would be 12" from the box plus 7" from the ITS. Plus all the steering that goes through the ITS system. You would most likely have to get a standard transom assembly to go with the extension box...plus external steering. That would add up $ quick! But you would be able to sell the ITS assembly to offset the cost. Maybe play with some more props first.....

I ran the boat with a 4 blade bravo and it chine walked a little.Did you runn it with the tabs down a little yet? Those tabs are 20 inches I believe, I realize they will scrub some speed. what about putting a spacer in for the imco? the x is too high correct?

Are you measuring the bullet on the drive at the bottom of the V? The drive bullet is the only thing that matters.The 5 blade makes it too squirley ? I only ran it with a 4 blade. I also didnt have more than 20 hrs on the rig when I sold it to buy my 382 formula.

No Brian ,,He Is Too Low,, Don With What Your Telling Me I Think You Are Gunna Have To Do A Reglass On The Transom To Get To Where You Want To Be,That Drive Must Be Real Low,If You Put A -3 On There It Should Be Right Around Where Mine Was,,Put Up Some Close Up Shots If You Can So We Can See ,,

I am going to call Merc Racing tomorrow (I am a dealer). I recall an ITS with a 3"rise. If they do maybe I can change the housing and not everything, it may be better than a reglass. But we have done many reglassing projects so either way I want it right. I need to get it straightened out before I start my 115MPH project.
The bravo did work much better, tabs helped some but to get it under controll it scrubed t much speed.

Let me see if I can get some close ups in the morning, The boat is at the Marina and I just got home. I will see what I have here also.

Thanks to everyone for pulling together and working this out with me, I apprecaite everyones time and effort.

Some more, prop shaft parallel to the bottom of the boat. Looks like 3.125 below the bottom of the hull.

My friends second Kryptonite is set up with 2.75 inch x-dimension,no box or its. He had the boat built with out pad and with knotch. The boat ran 108 on gps 800hp 32 b-1 @6400rpm. Removing the pad improved the handling of the boat.

I built one with out the ITS standoff and it is 3.25" and runs great, but the same X with a stand off box is putting the drive therotocally and actually much deeper in the water. I am sticking with the ITS on this one, I just need to figure out a plan to raise it a few inches.
Any pictures of that bottom with out the center pad?
