Just looked at a friends boat this weekend that was in salt water for one season, Apirl - October.
He relocated his boat from the entrance of the maria into a more protected slip into the inner lagoon. His new location obviously has a major electrolysis issue. All the zincs on shaft, strut, keel were completely gone. Minor Pitting on the prop and strut due to the zincs being completely eaten away. Note nothing changed other then location, and never had an issue before.
Checked all dc grounds on boats bonding system, negivtive on batteries, dc panel, bildge pump connection, and so on, everything appears good. I don't think the issue is coming from his boat, I believe that the issue is stry current near the boat that could be another nearby boat or possible stry current from the marina.
We have contacted the marina manager to look into this issue, however have not received any response
My suggestion is to add more zinc anodes plus two hanging zincs fore and aft that are bonded to the grounding system of the boat.
My second suggestion is to haul the boat mid season, inspect and replace the zincs if needed.
His thoughts are add more zincs and attach a battery jumper cable to the bonding system of the boat and attach the opposite end of the cable to a grounding rod driven into the ground in the parking lot. I think this is a bad idea. I'm not an electrician so I can justify my reason other then a Gut feeling.
Any feed back or realistic solution that I can pass on to him would be greatly appreciated.
