When reinstaling my prop, should I coat the taper with some kind of grease or anti sieze compound? If so, what kind?

I have never heard of any doing such a thing. I believe it is not required. Grease or anti-sieze is usually used to prevent corrosion in high temp or high moisture applications. Since props are nibrile (sp) or SS and the shafts are SS, neither will corrode and fuse together.

I always use a little waterproof grease on the shaft before I install the prop. It makes it so I don't have to crank really hard on the puller. I have left the prop on for 3 years and still had it slide off with a little tap of a plastic mallet.

The prop and shaft will not corrode together. The shaft is stainless steele and the prop is nibral (nickle,brass,aluminum). The tapered shaft and the tapered inside of the prop are "wedged" together causing it to stick.

To me, it sounds like a recipe for a sheared keyway and/or distorting of the slot if it were to slip every fwd/rev.
Lap the prop to the shaft so the tapers exactly match, and removal problems go away.

IO's & outboards have grease on the shafts because they have splined shafts. The idea of lapping the new prop to the shaft is a good one. Also if it is stuck remove the prop with a prop puller.
