I just bought a 1984 1650(16'.7") procraft bass boat with a 1990 johnson 150 gt, that i absolutley love! The motor appears to have never been touched, and runs great. My problem is, as is most of us, "I wanna go FASTER!" I just got a high-jacker 5" jackplate for putting a tranny line fitting on a jeep cherokee.........sweet!!! I'm borrowing my grand fathers 22 pitch raker prop, that i'd like to get off asap, considering it belongs to him of all people! I think i need a bigger prop. But I aint got the money to buy a bunch of props, to find out which one works the best. So can anyone tell me where i should start? Also the jackplate.........ima beef the transom up with sum 1/4" aluminum I scrownged up.... But where should I start with it. How far down should i put the bullet? I'd appreciate any feedback. I'm new to the site, but have read some pretty interested stuff sofar, and my dads spoke very highly of it as well. So anyways, thanks...
