Folding/Feathering Props

Have had the Flex-o-fold on for a year and a half and I love it. 
No problems and it gets me motoring at 7+ knots if I want to push.  Backs up very well also.  It does require an special zinc however that is a little pricey.  They do last for about 5 months however. 

Good company to work with also.

Only 5 months for a prop zinc?  Wow. . .

That doesn't seem like a long time.

  sure isn't but we've a hot marina and all the boats around me (and my boat also) are plugged in and charging all the time.  This seems to be the case for many others also. 

I wonder if a grounded zinc on a wire overboard would help?

Anyone with experience doing that?
