[QUOTE="Johny25, post: 273088, member: 7791"] Oh and with the speed, prop pitch, RPM, and gearcase ratio you have a 14% slip currently. My guess is that a stainless could drop this to 12% or less due to the better cupping and design that stainless usually has. I bought a Solas stainless prop for my 30 hp johnson and was very happy with the price ($175 shipped) and the performance gains. I have yet to buy an SS prop for my 9.9/15 johny but if I ever start using it again on a regular basis I will purchase one for sure. [/QUOTE]
