So I broke the prop on my 25 hp mariner and bought an aftermarket prop. It's a Vortex (supposedly) performance prop 10 1/8 X 13p. Well it's not the same as the OEM prop for sure. It fits ok but the difference is that the center hub is larger so it has less of a blade. It was about $30.00 less so I went for it. Out of the hole I think it's cavitating and WFO the motor winds up too tight but haven't confirmed that yet. Definitely more RPMs though. Anyone else have this experience?
