Hello
I have a Fountain 38 Express Cruiser. Motors are freshly built with stroked forged internals, upgrade cam with whipple superchargers.
Power is roughly 700-750 Hp. The reason for the build is that I boat at lake Tahoe which is at 6200 ft elevation.
I just order new Imco SCX uppers.
I plan to use my bravo 3 lowers.
My question is has anyone done or know of someone with this setup?
Any feedback or comments will be greatly appreciated.

You might talk to John at The Bravo Shop to see if he's done this on a boat at LOTO. I know he rebuilds a lot of Bravo III drives for Formula SS's.

That will be a interesting set up.

I've heard of a lot of setups using SCX upper and SC lower. Isn't the SC lower basically the same as the Bravo lower?

The SC lower uses XR guts 1.25 prop shaft, housing is totally different.
