I just became aware of the fact that I could buy a stainless steel prop for my 15 horse johnson. Does anyone have any experience with these on a motor that small? I know the performance gains on larger motors but not sure about it on a 15. Right now I have a 9x11 aluminum on it and run 25-26mph on the gps with me and my fishing gear. Not sure I need to go faster in a 14' boat but it would look cool to have the shiny blades hanging off the back.
