A guy I befriended a couple of slips down the pier
said that this boat should easily be able to go 25-30 with that engine
and the reason why it can't is probably stuff growning on the bottom.
I intend to have it pulled out and bottom cleaned/sanded/painted and
believe that could speed it up, but it's hard to believe it could have
such a large impact. Any thoughts?

If the bottom of your boat looks like green shag carpet, yeah, that could be
the problem.
