I am running an aluminum 4 blade Solas 19P and a factory aluminum 21P. Both use the same thrust washer. I have an old stainless 19P that came off a Cobra that I had rehubbed for my SX. It seems like the thrust washer is too thec as there are no splines sticking through the hub so I can't key the splined washer. Does anyone know if there is a thinner thrust washer I can order? I would like to try the three blade stainless on this boat. Thanks!
