O.K. guys, I replaced my prop on my Evinrude 1962 40 h.p. model #35933 motor due to a spun hub. This motor has the shear pin prop with the plastic (nylon) prop nut on the end of it covering the prop shear pin and the prop shaft, with the cotter pin thru it and also thru the shaft. When I first put the new prop on the motor, the hub was flush with the inside of the prop housing. It is now working it's way deeper and deeper into the prop housing and sticking out of the prop more and more on the outside of it. I am seeing skinny rubber fragments on the inside when I remove the prop. Seems like this prop is ready to be a spun hub too! I only ran the motor three times since replacing the prop, and not in any weeds. What could be the cause of the spun hubs??
I noticed in my Seloc manual that there is some type of washer under the prop, between the prop and the motor bottom unit gear housing "ON CERTAIN MODELS". There is no washer and never has been a washer there in the three years that I owned this motor. Could a lack of this washer which "MAY " belong in place be causing the problem I am having? What kind of washer is it that should be under the prop?
Thanks for your input!
