The IMCO uses a extra long drive shaft, so you just can't swap drives. You also need an extra long drive alignment tool. The IMCO box also doesn't allow the drive to be adjusted for the x-dim. Once it's set, the entire engine and transom assembly must be moved.

Is your prop blowing out or losing bite to where you have to play the throttle to roll the boat on to plane? Or does it just seem to take a long time? The reason I ask is that I had difficulty planing my 28 Daytona with twins until I went to 5 blade props (Hydro P5X's). They instantly took care of the problem, so you may want to consider your prop selection before raising your X dimension. I can only imagine that a shortie would make your situation worse. Another thing about the P5X's, I gained about 4 mph at 3500 rpm and the boat handled much better.

I am using a labbed 24 or bravo labbed 26. I cannot get the prop to blow out. it bites and will not let the engine make any power. I was told to change gears to 1.50 or try a 2 inch shortie.

The Imco boxes use a torsional drive shaft and a stock Merc rubber coupler. The Stelling box uses a solid driveshaft bolted to the flywheel. Imo the Imco is better because it absorbs more driveline shock. I think it's one reason the drives on my Black Thunder have been living with the hard life I've been giving them.
