I used to have a 23' with twin 150 Yamaha SWS's. It would top out around 44 MPH. Since the engines were carb, I would avereage about 1.6 miles per gallon.

The SeaCraft hull rquires power to push it. I have a friend who has a 23' Parker SE CC. He can push his boat with a 200 HP, and can move quicker & gets better mileage than a 23' SeaCraft with a 225HP.

I now have a 23' SeaCraft with twin Yamaha 200 HP OX66's. This boat I can push into the mid 50's.

Any idea on what your RPM's on the ETC's should top out at? Have you considered different prop's?
