Prop pitch/selection determines most of your top end.
When I was working for Gekko boats, most of 'em would top out around 55 or so, but get there in a hurry. With a race prop (and 375 hp PCM engine) the same 22 ft boat would do a tick over 70, confirmed by GPS.
I could easily hit 55+ on my 21 foot boat with 275HP. I was running a 23 pitch, 3 blade stainless prop.
