Re: which boat
Most light weight 15-16' boats with planing hulls will fit the bill for you, Dante.
My favorite in that range is the 15' Boston Whaler (classic 15', not the newer 150). It came in several configurations. I have the Striper 15, DWJ has a Sport 15 that he is customizing; I think to a center console.
That boat with a 50 on it should top out at about 35 with one person and a light load, 30-33 with two aboard and more of a load. Mine with 2 adults, 12 gallons of gas and fishing gear for a day on a big lake tops at 32 and cruises well at 28-30.
For less bux most of the 15-16' aluminum semi-vees do well with a 50.
Good luck.
