I have a 89 Johnson GT 150 on a 89 18.6 Javelin. My prop is needing to be re worked ( I hit something). The prop guy says he may not be able to do it due to the amount of times its been re worked. Anyway, the prop is a 3 blade 15 1/4" RAKER with a 24" pitch. I wanting more speed. Im running around 60mph at 56k RPM's now. Is that gonna be the max speed with this motor? If I go up or down on Pitch, what will happen coming out of the hole and top end speed.
