Certified marine techs looked it over: my engine
created a charge, so it did originate in the boat. The previous owner reversed some wiring
on the panels
too- all will soon be resolved. So the flowchart now seems to be - sandblast the lead part of the keel-> apply 3 coats of Interlux
Interprotect HS-> fair the lead with epoxy
. The keel bolts
checked well and structurally the pros said that the lead portion isn't going anywhere and if the stray current issue is resolved, it won't get damaged by corrosion
NEW QUESTION: No one seems to have heard of/seen my keel situation before (please see pics in album for reference). Forgive my newbie understanding of keels: The Columbia
9.6, a fiberglass
boat, had a fiberglass
keel. Displacement/ballast weight comes from somewhere, so is it fiberglass over lead? The previous owner did that 90 degree angle lead replacement in the pics. I assume the boat ran aground and that was his fix, be it good or bad. So do I now have a partial fiberglass keel and partial lead or is the whole keel lead, but some in exposed and some not?
I ask because if all is faired over and painted, it should look good and be structurally strong. A suggested option is to glass over the exposed lead after the above flowchart's fairing which would make it even stronger structurally and would eliminate the stray current worries on the keel permanently. Is this a good idea?
It is a costly job with tradeoffs: I'd need to install a new lightning
ground plate on the hull
. Also another opinion offered AGAINST glassing over is that any damage to the glass and I can no longer SEE the damage to the lead getting eaten. He suggests this would NOT be a permanent stray current/electrolysis/galvanic solution - only a temp one as everyone runs aground at some point.
So in a nutshell, I'd love to know how you all would do your keel if it looked like mine.
