Ok Prop question.

I understand that the pitch is the theoretical distance that the prop would move per rotation Â… and that by changing this your WOT will change by 3-500 RPM Â… but what about diameter..


I have a 13x19 aluminum prop (that has the engin running just right at WOT) but want to go to Stainless. Should I get the same size and pitch? What would happen if I went up to a 13-1/2x19 or even 14x19 stainless? Any suggestions as always are gratefully received.
