This is a lot of good information.
To achieve a good electrical
contact between the "zinc" and the sail drive (as I have seen a good bit of corrosion
and scale there), would it be advisable to smear some water
resistant grease on the connecting face, like on battery
terminals? I used to assume the bolts would be the conductor, but I've since learned that SS is not the best conductor. 'Though perhaps it's good enough with the voltage involved.
Just trying to help my sail drives as much as I can! Since I installed a galvanic isolator
, I can't complain about the life of my zincs. This haul out
was delayed, and the zincs were 3 1/2 years in service
. Still a lot of zinc left.
