i'm trying to figure out who made this prop. it's a 9 1/4 x 11 with the number #522011 stamped on it. it's 13 spline. it's supposed to fit a late 70's johnson/evinrude 25hp. it's a non thru hub exhaust. michigan wheel lists pin drive all the way till the thru hub came out in 1984. the 28hp SPL and the 25hp commercial used spline drive w/o thru hub but i can't find that number listed for either of them anywhere. does a prop number starting with a 522 ring a bell to anybody? i could see where the 011 on the end could stand for 11 pitch but it could also just be a coincidence.
