Thanks guys.

The Seavette is heavy so therefore it's not super fast compared to a Baja of the same size. I'm getting 58 MPH out of her and this is full of fuel. This boat is a little heavier than the center console SeaCraft boats so I guess that isn't too bad. Seems like I saw where someone's center console SC was running 56 MPH with twin 200's. I'm thinking that the Seavette is making around 450 HP at the flywheel. What surprises me is the fuel economy. The worse that it has gotten so far is 2.19 MPG and the best is 2.44. It will cruise at 40 MPH (3400-3500 RPM) and get 2.3 MPG.
