Re: VC 17 Bottom Paint electrolysis
That's pretty severe ! Are you sure you don't have positive voltage leakage to the zinc from the boat's wiring? Possibly a bilge pump wiring broken?
Are all your thruhulls bonded and if so, are they showing similar symptoms?
I installed a sheet of vinyl between zinc and hull on my boat.
The vinyl doesn't need to extend past the zinc, just prevent the zinc from contacting the paint.
