Just wanted to say that I purchased a 6" fly wheel puller, here: https://www.amazon.com/gp/product/B06...&psc=1 and then took the three arms off. I then got three lengths of chain, 10 links each and made loops connecting them to the arms of the puller. Wrapped the chain around each blade and started to tighten. A few taps on the center spindle and then the blade did the trick! It came off nice and smooth without any undo force. The spindle was corroded but not much, it cleaned up and a new factory prop is on its way. Thanks for the puller idea.
