I have been trying to get a little more performance out of my jon boat. It has a 1981 Evinrude 35hp and the boat is a heavy 16ft 1972 polarcraft. I added a big casting deck out of plywood, bow trolling motor, storage compartments up front for tackle. the Troller is 24v system and i don't have enough room for both batteries and gas tank back by the transom so one of the batteries is about mid point of the boat on the side. I first added a CMC pt 35 and thought i might get a little speed out of it, but after playing with engine heights i'm still getting about the same performance.
I am currently running a 10.5x11 solas aluminum prop and it turns about 5400 rpm WOT with just me in it and i get about 25.5 mph. I have two 10.5x13 pitch aluminum props that run about 4600 rpm WOT.
I am wondering if i went stainless if i could get any more speed out of it? I am sure if i redistributed the weight in the boat i could help it out that way but i like my layout the way it is. I swear i saw a thread somewhere of someone testing various pitches of both stainless and aluminum on a similar setup and found that he had significant performance improvements with the stainless and I believe he was also able to go up a pitch but i can't find that thread anywhere now. Ideally i'd like to get up to the 28+mph range, which sounds insignificant but when you are fishing the Mississippi river with miles of backwater it would help to extend my fishable range.
