Loose Through Hull

[fishaholic18]

Found this:"You need to wire together all your underwater bronze
thru hulls and run a grounding wire to the engine
block to avoid electrolysis."

Hope that helps.

I consider 5200 a permanent install. It's a real PIA to remove anything installed with it. That said, remember, your fittings can be attacked by the electrolysis coming from a neighboring boat, whether in a slip or on a mooring.

Just went to West marine ONLINE to look at fittings and I saw an article on grounding. here what it said about thru hulls. I think this apples to mine.

Zincs and Protection from Galvanic Corrosion

An isolated bronze thru-hull doesn't need protection because it is not in electrical contact with another immersed dissimilar metal. If electrically isolated, high quality marine bronze, is electrochemically stable in seawater; nothing good can come from connecting wires to it.

Worked out well thanks for the help.

Got that 5200 quick cure and it worked great. Got everything apart with out much trouble. Then got ripped off at West for a new valve 34$.

To get the fitting out, I took a 14mm deep socket and used a die grinder to make the perfect tool. Should be floating this weekend.
