Best prop for '03 F75

[muskydope]

As stated I have a F75TRLB mounted on a '03 Crestliner Fishhawk 1750, with 2 guy's top speed is 34mph @5450 rpm. Current prop is 13x19K Yamaha aluminum, holeshot is good. Using the prop calculator I come up with 19% slip. What would be a prop that would give me more speed?

You could try a 19 SS prop or a 21 pitch alum but the rpm's will drop to lower side of rpm range(5000-6000).

Thanks for the reply, I think a 21" might be a little too much. Would the 19" stainless be a direct swap? I see Yamaha offers a stainless version of the "K" series of props. Would a stainless have less slip?
