Thanks Pantera.
Those are probably the same or at least similar dyno data sheets I've seen before so the performance is real to me. My greater concern is fitting CMI's in with Capt's Call and what prop set to move up to in a B3x.
I'm not convinced , quite yet, it is a simple matter, but hey, thats why I'm askin'.

You will have to finess, modify, and play with the fitment. Move up one pitch size in props if that. I think you'll be lucky to spin those at redline. Im afraid its not going to be nite and day performance. At least it wasnt for those I know that put them on single motor boats.

I purchased a pair of CMI's for my '07 232 that had a 496 HO motor and I would definately not do it again. The modifications and time involved to install were enough to make me want to sell the boat.

Quantifiable results were gained for sure and the look was killer, but seriously, plan on spending quite some time in the engine hatch.

I put a set on my 496 ho mag and picked up 5mph (gps)
It did take about 6 hrs on the install. But worth it.
