Looking at the sacrificial anode on my propshaft by the propellor after craning out last season, I was surprised by the uneven wear. While one half was considerably eroded, the other half was almost untouched. As the two halves were new and clamped around a clean shaft at the beginning of the season, I am quite surprised at this uneven wear. I don't recall uneven wear from the previous season. My in-hull anode was in good condition last year and this year.

Has anyone else noticed something similar and does it point to anything sinister?

Really this could only be one of two things. Either one half had been covered with antifouling or grease or something, or it was made of a none-corrodable substance. So long as one half worked and there was some part of it left when you lifted out I shouldn't worry about it.
