I was wondering what the best prop/pitch is for my boat. As of now I am running a 14.5" prop with 19 pitch, and of course i would like more top end, but not sacrificing getting out of the hole. I was wondering what everyone is running at WOT (wide open throttle) with their boats, and what is a safe range. As of now I run about 4,200 RPM WOT; the prop i have now is aluminum and would going to stainless steel help? Also what would be best for economy?
