Finding electrolysis at the dock
 

Our marina has a problem at some slips with stray current. Some of the
boats are loosing zincs at a fast rate while others are not. Looking
for some help in trying to resolve this and what kind of equipment
will I need. Thanks. Chuck

I don't know what you expect to do. The marina has to fix it. We had
that problem for two seasons. I got a little testing gizmo that plugs
into a grounded receptacle and lights various LEDs to tell what is
happening.

The ground on one whole dock was open. That was over 100 boats. They
did fix it, but I had to have a diver replace zincs partway threough
the season once.

Rodney, This is a condo marina. They will fix the problem but have no
idea how to track it down. Since it directly affects my boat I will
try and assist them in finding the source. That is why I posed the
question. Chuck

What I did was take the little tester gizmo, along with a pigtail that
converted the dock outlet to an ordinary 3-prong outlet, and plugged
it in to dock posts all over the marina.

In our case it turned out the ground was open over the whole north
dock, which was half of the marina. The south dock was OK. So, the
break was at the connection from the floating dock to the solid.

An open ground may not be the only cause, but whatever it is may show
up with the ground tester.

I normally do not keep my boat at a marina but did once for a couple
weeks. I dove to unfoul my prop and felt weird in the water, found my
zinc had dissappeared in less than a week. While looking at the zinc
with mask and snorkel, felt "tingly", suddenly realized what was
happening and got out of the water very carefully without grounding
myself to anything.

When you figure this out, can you post it so I can do the same?

I was looking at a "Corrosion Test Meter" that is made by Guest. The
description in the West Marine catalog indicates that it might be just the
thing for this, but it doesn't give quite enough information and the Guest
website is useless. If this meter is the thing, I might consider buying
one, or if you buy one I will buy it off you (or rent it from you) when you
are done .
