Try a prop change to get the rpm you want and see if the speed goes up with more available power. I think the number on the speedo is more important than the number on the prop. I don't know if you can find a definitive answer on ratio and prop combos. Its trial and error. Unless you find the exact same comb on another boat like yours. Good luck,
