I need to remove the prop on our Duffy because of excessive pitting issues. OK to use one of those screw on the shaft Prop Knockers to remove the wheel?

Some guys say that the banging causes stress to the tranny....if you were closer i would lend you a puller

Yes a Prop knocker is fine. Make sure it is nice and tight. The prop knock and hammer hits are a lot less stress that shifting from forward to reverse to do not worry. If it is real cold or the wheel is stubborn some gentle heat will help.

I use a prop puller...sometimes you cant get a square swing with a big stainless rudder in the way...but like Travis said....its your wheel(boat)

Turn the rudder hard to port or starboard. You should get swing. Knock offs are all they use at my marina for wheels up to a 2" shafting.
