Kendal I have the ITS and I dont think it does help any with the deep V and the already long length for a single running at my speed at 80... No issues handling

I'm just puzzled that with 775 hp I'm only going 84.5. I did do 90 once, but since that one time I can't break 84.5. Maybe the motor is missing somwhere. I wished for a 28 skater with O/B for christmass but didn't get it!

ITS isnt adjustable The center of the lower unit is 1 1/2 " below the bottom on my setup. I tried a 1" spacer a while back but liked it better without.

Temp and humidity and water cond. play a huge role in how my boat performs. I've had many different results on different days...

I believe the JCap did the most testing of anyone on the Y2K.
The extension box did not help and neither did a shorter drive.
I believe that on the first generation Y2K hull, the factory set prop shaft height of 3-1/2" below with no extension is about as good as it gets. JCap did run with a 1 or 1-1/2" spacer for racing but went back to the stock length for reliability reasons.
The Zuperboat is the only 30' Super that we've talked about here that ran well with an extension box. The boat is vary light and has the tempest deck. I'm sure Mike is happy to tells his stories again.
