hey there im currently looking at purchasing a new prop for my boat. at the moment i have either the factory prop or a remanufactured one its a 13x19 on a 1972 mercury 1150 115hp thunderbolt. ive been reading old posts on here but the issue with most of them is the boats are newer..mine is a 1991 Vision 16.5 ft bass boat. some more info on the boat that i know of is it was 100% hand laid fiberglass boat...the hull is a fast design. not sure on the weight of it since there isnt much info on these boats since the factory went up in flames a while back. right now im getting 40 to 42 mph out of it right now and maybe around 5000 rpm by sound no rpm gauge. i know its possible to get more out of it since i talked to a guy that had the same engine as i do and the same length boat and did around 55 to 60 mph...passed me like i was standing still. im goin to be doing fishing tournaments here soon and i need that hole shot and the speed that goes with it, any help or advice on this would help me out a lot
