Yeah get a motor/prop/gear box that matches the task.

Your friend is lucky that the lake speed limit just about matches his boat’s max displacement speed. On paper it should take 5 hp to move a 2k pound 20 foot hull thru the water at the speed limit. Get an engine that produces 5 hp at 1/2 -3/4 throttle and you should be as efficient as possible with some reserve for wind, extra ladies etc.

A classic black merc 7.5 (with merc’s work boat/displacement prop) maybe? sexier,lighter,simply better then a modern 4 stroke.
