15x13 or 15x12 Prop
I currently run the OJ 945 which is a 15x13. Would I gain much by getting a 15x12 prop. I run a lot of weight and noticed my RPMs running pretty high. Thought this might help. Plus I haven't spent much money on the boat this year.

15x12 you will run higher RPMs. I run a ACME 2313 which is a 15 x 12 but with .150 cup to keep the RPMs down some at higher speeds. Switching from a 15 x 13 to a 15 x 12 will get you more torque and low end power and sacrifice top end speed.
