Boat zincs gone in 2 months? The zinc probably isn’t the problem.
Stray current from shore power, a battery, or bad wiring can burn through sacrificial anodes far faster than normal. Check these first:
1. Shore power ground on your boat and dock
2. Galvanic isolator
3. Bonding system
4. The boat next to you
Fast-burning anodes are a warning sign. Replacing them without finding the source just pays for the problem again.
Send this to the boater who keeps buying zincs.
