The zinc annodes were installed by the marina on my bravo2 legs/drives connected to 5.7 mercruisers . Saltwater use. no shore power for 6 weeks. Whats gasvlanic corrosion? Sounds expensive!!! And more to the point......how do I stop it?
Hope this helps your advice.

I put new annodes on 6 weeks ago and looked yesterday. As I previously suspected, there must be a current leak somewhere because one annode on one leg is zapped to about 70% and one on the other leg is about 75%. The strange thing is all the other annodes on the legs and the big one on the hull...
