If your zincs are getting eaten up this might be the problem.
To change the grounding bar you need to get the bilge dry and have about 3 12 inch extensions for a socket wrench to remove the  keel bolt that it is connected to bar.»

Our zincs are not getting eaten up, but our diver reported this week that our keel shows "veins" of "orange" material "erupting out" that looked, in his opinion, "like electrolysis" (words in quotes his).

I dismissed this all week long thinking that the keel bolts were connected to nothing, but now am curious.  And keen.
