I have the same 2GM20F engine in my current boat, a Bristol 30 that officially weighs 8,700 pounds as opposed to the 32's 9,600.
I regularly reach 6.3 knots in flat water at 3,000 rpm. It cruises comfortably at 5.5 knots at about 2,300 rpm. I have a two-bladed prop at 14 X 11 in an aperture. It's a little overpropped, but it works fine for now. Jack Brennan Former C&C 25 Shanachie, 1974 Bristol 30 Tierra Verde, Fl.

I get about 5.4 at 2700 and 5.9 at 3300 rpm. I have a fixed 2 blade prop. Other than that, you got a great boat.
