{Stus-List} Do WE Need a Zinc on the Prop Shaft Strut?

I (and apparently the prev. owners) have not had a strut zinc for 28 years, no problem. I do use up the better part of a shaft zinc or two a year. I also don't connect to shore power very often, as I sail weekly and run the engine at that time. I also have a small solar charger. I'm not sure why a strut zinc would be needed, as the strut is isolated from the shaft as well as the rest of the boat. Not sure where the current would be going.....

  I've hauled out for new bottom paint and the boat yard manager says I need a zinc on the strut.

  It doesn't appear to me the strut has ever had a zinc; no holes or anyway to attach a zinc.

  I have asked other local boaters and it seems they are split on requirement for a zinc on the strut.

  What says the list?

  Any reference to same would be appreciated.
