Looking for any advice on props for a Suzuki 300 on a 24' hull. I am currently running an 18.5 pitch, but I am only turning 5500 rpm trimed out. I am still breaking it in, so I was just able to run wide open, my mechanic wants me to get 10 hours on it before we start swapping props. Just wanted to see if anyone has any experience with this set up. My MPG is down from what I was expecting as well, 2-2.5 on a medium load is what I am getting cruising at 4-4400 rpm, several on this site say they get 3 or better.
