Quick prop advice

[Brummo]

I have a 2011 75hp Optimax on a Tracker 175TXW. Current factory prop is a 13x19 aluminum. Everything seems to be right on as far as performance and rpms are concerned. Just wondering what to expect with the engine/boat combo if I go to a SS prop. Any size adjustments? Stay with the same pitch? Looking for maybe a bit more top end mph, but not worth it for 1-2 mph.
Thanks

Usually can go up 2 pitch higher when going to SS from aluminum.
