Thanks Donniercjet, I got it off! Man I must have been in a coma or something the other night when I was trying to get the stupid thing off! About 15 minutes after posting the question, I figured I would just take a peice of stainless rod I had, place it on the prop shaft, brace the fan shroud on the edge of the table and then tap it lightly with a hammer! Presto! Just one very light tap and it loosened right up.
Thanks,
