I may have "pushed" the transom varnish weather LOL.......
The little 12ft Crestliner did 30 with a 35hp. I'm not sure I could better that in either boat with trim or otherwise. At the moment, the largest I have (it's apart, lower unit) is the 55hp Chrysler/ Sea King which came on the "free" boat which I junked. It's a fairly light twin, much lighter than the old Johnson/ Evinrude V4 50 hp I made a front shelf for the Crestliner to hold the fuel tank.
This is before I built the shelf,.........and before I cleaned up the lower unit
