I’ve got a 2006 75hp E-TEC tiller on a 16’ fiberglass multi species v-hull boat. The motor is not original to the boat, it was used and came off another boat, I think a pontoon with a steering wheel and remote controls and was converted to a tiller, but I’m not 100% sure on that.
The motor is currently equipped with a 13 1/4 inch prop in a 17 pitch. The boat seems like it takes a while to get on plane, it only goes 32-34 mph (I feel like a 16 footer with a 75hp 2 stroke should do a bit better than that), and most concerning to me is the fact that at WOT the RPMs only reach 4250 rpm. Ideally, I would like for it to run at 5000-5200 at WOT.
I’m thinking about maybe going to a 13 1/2 inch 15 pitch prop. I feel like that would allow to boat to place out faster, put less stress on the motor, allow the engine to hit that 5000+ RPM mark, and maybe even gain some speed allowing the engine to rev out all the way.
I am by no means an expert on prop size/pitch. Just want to make sure I’m on the right track before I pull the trigger and buy anything.
