Great build!

Pat,

Based on the performance of this hull with 350's, what would you expect it to do with a pair of 400's? If you built a 37 with OB's what would you expect from twin 400's or triple 400's?

Triple 400's on a 37 would be the cats a$$. Most likely run high 80's with a 5 year warranty.

Yep

Mite as well go with Quads or some 1100 or 1350 turbo's

There's a few words that can describe Active Thunder's newest creation:

Well done Pat!

I hope you sell the hell out of these, so that in 10 years, I can afford to pick one up used!

I think this doesn't look anything like a 33 Active Thunder. Outboards are only popular because of all the #$*@@ engine builders in this country. I still prefer the sound of a big NA engine that and the look is much cleaner in my opinion.
