Being in fresh water, I never needed to coat a prop with anything. The one I bought from Ron a few years ago still has the original galvanize appearing coating was on it when I got it... Very little has worn off.
Ah, the delights of sailing in fresh waters! Boy do things change in ocean environments!

okay, so time for part "B". The yard guy came by with the prop puller and asked if I was going to put something on the shaft before the prop. Never thought about it, though I know nuts and bolts get lubed. Other ideas for the prop???

what are the two materials? Stainless shaft and bronze prop? Or?

I think you want to keep the electrical connection between the prop and shaft. Putting a lube in there will prevent that.

I never applied anything on my J Prop propellor. I installed that prop 4 years ago and I mirror polished it before installation.
Since, every year I scrub it with a piece of hard wood cut in bisual to clean the minor things on it which cannot stick with the mirror polishing. A little more polishing before the boat goes back to the sea and that's it for a complete year.
It's about one hour year every year.

I'd use a thin coating of a good waterproof grease.

But, having had to remove props after years of being on a shaft, I think I'd like a little something to help with removal at some undefined later date. I've had props pop off without much problem (lovely!) and I've had props stuck on so hard the question was do I have to destroy the prop, or destroy the shaft. Never had to go down that road, but close. I also don't do this kind of work anymore, so perhaps it was just my luck at the time.
