Well without knowing more about the boat, I'd say a '53 GMC 3/4-ton will pull just about anything as long as you're not in a hurry. I own several old GMC's and if I could find a nice '54 or '55 1st GMC COE I might ditch all my Chevs in favor of Jimmys. But lots of people already think I'm nuts.
The best source of information on GMC trucks of that era is
OldGMCTrucks.com. You'll find lots of info on the web site, plus a forum dedicated to GMC's.
Its a no BS kind of place with lots of good info.
Thank you very much I know have a lot more information on it then I did. Also To the guy that said looks like I skipped alot of the dirty work?
The PO painted right over the rust, the engine is all rusted over, muffler pipe looks like if i touch it its going to turn to dust the frame looks clean of rust but that is about the only thing., now moving into the cab under the dash there are 1000 wires (not really a 1000) hanging everywhere not connected to anything, upholstery is in decent condition but still not great one small tear on the seat piping, the upholstery on the roof is falling off I am adding some pics of the interior and engine block ect to my page soon (next commercial break the SuperBowls on right now.)
**EDIT**
20 new pics of all views on the truck
