Mine's a little over 1 mph faster turning in.

Prop blowout when coming on to plane
was much worse when turning out.

As far as the docking issues when turning in,
I've found that leaving the drives trimmed
slightly positive helps.....it's still not as good as when turning out, but it's better than if they're trimmed all the way in.

I think spinning in is more effective on boats with drives very close together and stepped hulls. On my Sonic 31SS with the drives 35" apart on center and stock 496HO's, I saw absolutely no top speed difference whatsoever. I didn't experience any docking problems, either. But, the only way to know is to try. This is easy with Bravos. Just swap your props and run the sticks in reverse to go forward.

This was the response I got from Gar so I am switching mine back to spinning out this spring.

Bill, yes...all the 33 & 28 twin engine I/0's and O/B's run best with the props rotating outboard. Every boat size & model PowerPlay, even the 25's, were delivered this way. You name the combination of power, propeller types & brands, payloads, ocean & calm water conditions, climate, racing, pleasure, etc., and it was tested & proven for years at PP. How the boat running? Gar

My boat came from pp as a 2 man race boat with staggered #4s on boxes...now it is a side by side set up, with a full cabin, and a pleasure cockpit...so nothing is constant except the 4's and the boxes but they are now side by side

I was wondering about this with #3 SSM's. I am going to try spinning in this spring. The big pain in the butt is you have to acutally change the drives. It is an 86 Cafe, anybody else with something similar?

You could swap lowers but I think swapping the drive is easier cause you don't have to mess with the oil and all that....

You really need to talk to PP guys that have done this. I've talked to a few about other things and chinewalk or poor handling might come into play! Is your boat the B boat in your avatar? do you have any of the original race parts? I might like to pick them up if you do...
