You will want to look for one with a drop box, ASD6 have helical cut gears that can take a max hp of somewhere around 500 I think. But straight cut gears would solve that.
The hull shape and center of mass have a huge bearing on how well it will work. On a surface drive boat you want some rocker and absolutely no hook.
Do some looking, and if you find a potential drive, ask questions about it specifically.
great suggestion, thank you

For all you doubters, Bjorn in Sweden had a 22 Classic that ran 112 mph without insane power and without any hull mods. A lot of people assumed he had added a pad but I talked with him and he did not! Bravo X drive. HP and prop not disclosed.

^^^ Wow he’s moving! Got it aired out nicely. Wonder what he had for drive and prop. Pretty sure I bought a pair of 3 blade cleavers from him.

To the OP, I can’t offer any input on the arnesons or other surface drives, but I say see how deep the rabbit hole goes!

Doubters of the capability of this hull, round keel and all. That doesn't look like a ton of hp. A pro-charged 540 and probably under 1,000 hp and a well set up boat. And who needs steps when you're running on the last foot of hull ....

Yes, that was a heavily modified 22’ classic.

so is the thought the 22 can’t go fast or did the driver make a fatal error not catching the instability sooner and finally, couldn’t any boat under 25’ or so do that? I’m asking not telling!

Yes. The one I posted of Bjorn is a stock hull. The one that crashed had a pad added and the bustle. And, yes, the pressure to make a fast run and adrenaline got the best of the driver. He obviously should have backed out of it when it started rocking back and forth.
