Propeller pitch / diameter selection

[redfishlost]

I currently own and enjoy a 2005 K14 Sundance skiff,powered by a 2005 25 hp F25 Yamaha four stroke engine.
The stock prop is 9 7/8" diameter x 9 pitch,and is aluminum.
The boat planes easily but doesn't seem to have very much speed.
It seem as though there is more power but much like a race car which has too low a gearing for the distance.
What would be a good selection of prop size and pitch for this combination of boat & engine?
Also,would a stainless steel prop provide any significant benefit?
Thanks!

RPM's at wide open throttle is the best way to determine which prop would be best. Might have your dealer check rpm's and suggest a prop.
