Folding Propellers: Zincs and More

I need to replace one Flexofold propeller on our catamaran with saildrives, and considering Gori as well as Flexofold.

Propeller zinc life expectancy seems to be an issue, and I'd like to hear what others have to do in this regard. My 16 year old Flexofolds have no zincs (I think the new FoF does), and on only one past haul out was any electrolysis seen.

FWIW, my saildrive zincs last the nearly the 2 years between haul outs. In fact, I had trouble getting hauled this last time, so it was nearly 4 years, yet the zincs were in good shape. I did install a galvanic isolator years ago, which has helped.

That one FoF is still OK suggests that I stick with the same, but it now seems to be a different model with a zinc.

So if anyone can share their experience-- zinc life or in general-- with either of these propellers, I would appreciate it.
