I have had similar problems accompanied by slower speed and even overheating issues when the buildup gets too much before I had her hauled last year.
I am working toward a wetsuit/hookah set up to dive the boat periodically to clean the prop and shaft. When she was hauled last July I cleaned the Maxprop and shaft and than applied the Petit spray paint product for transducers and props. I got a look at the prop at the end of the season via a friend's GoPro and it was still clean. No idea what it's like now, but I had get out a few weeks ago and the speed was about the same as at the end of the season. So, that's promising. As for your mystery, no idea.
