I took my boat out this past Friday and I noticed it was taking awhile to get on plane and when I got it home I noticed some paint peeling on the prop and I think the prop may have gotten hot. What would cause this?

Is this the first use of the prop? A lot of props lose paint on initial use. Did you hit anything? That will cause loss of paint as well. Has the skeg lost any paint?

If not, cavitation can cause the paint and metal to erode. Props are water cooled and I have never heard of one getting hot...

Props that have been to the repair shop are notorious for peeling paint. On OEM paint jobs, it is usually sandpapered off from running in the sand in shallow water.
