I set up an 81 38 Scarab a few years ago. Staggered w/ TRS. A lot is going to depend on the weight distribution. I was able to increase the X dimension by over 2 inches by moving some weight around. That gave me al least 5-6 mph and a much nicer ride. Is it a flat deck or raised deck 377? Does it have a full cabin? Are you running the belly tank or did you add saddle tanks?

First off, add saddle tanks. The boat rides like a pig on roller skates with the belly tank even half full. Moving the weight back will allow a higher X dimension, higher speeds, and a much better ride. 2 standard 50 gal tanks will fit easily on either side of the motors.
BTW, this and lightening the cabin also completely eliminated the bow rise when getting on plane, allowed the boat to plane at lower speeds, and virtually eliminated the need for tabs.
I set mine up for TRS, but there's another 377 w/o boxes and a relatively high X dimension that I know of. I can check to see what height he's running. There is also a standard "formula" for the amount of rise vs. setback that box manufacturers reccomend. I think Stellings had the rise built into the box.
Clearace for the motors to the deck shouldn't be a problem in the staggered setup. They're pretty deep in there anyway.

I'd definately post in the scarab section and even perhaps a boat manufacturer who's been around for a while who would take the time to help you out. That's definately something you don't wanna screw up. Just out of curiosity how far below are they currently. I bet if you call the Saber brothers they will steer you in the right direction if you don't get the help you need here.

The saddle tanks make sense for the extra weight in effort to raise as much as possible without the concern of prop blow out. Can always experiment with the weight very easy also. My 12 meter was converted from trs to ssm3's without ext boxes and are about 3" below bottom. But completely different animal. Very little weight in the cabin.

Located in Grand Rapids. They're great guys. Tell them John Read recommended to call. I owned there first 28' that is still on the water currently owned by another OSO member. I lived just a couple miles from their original shop on Alpine ave.
