I read an article(in Trailer Boats I believe)a few years back where they swapped out the intake and carb to a four-barrel set-up and picked up like 2-3 mph. I was surprised they got that much.

I have a 5.0 Volvo Penta vortex setup and swapped it to Holley spread-bore and picked up 3 mph. The VP stuff actually has a 4 barrel manifold and an adapter plate for the factory 2 barrel, so it was no brainier.
