Do you have a galvanic isolator in your electrical system? After I installed
one, the zincs on my saildrives were eroded much less. So much less that I
no longer use guppies.

We have a diver check our zincs and bottom every 90 days. We are in a
"hot"
marina with a lot of stink potters around which means the zincs can be
AWOL
in short time. A diver, $50 and a zinc or tow and you'll be fine.

Because of a miscommunication with the yard, my Alberg 35 was relaunched
after a haulout for bottom painting without replacing the zinc. I had
taken the old one off (not much left).

Years ago I had a friend drop a fish shaped zinc overboard every time he
came back to his slip. It was supported on a line for the weight, and a
wire from the zinc to....actually I don't remember what it was to, but I
think it was the green wire grounding system on the boat.

If I adopt a similar plan, attaching a wire to the zinc that did not get
mounted and attaching the other end to engine block or shaft, will this
suffice sufficiently until my next haul out? which will not be until
2006 probably....

I am concerned as the boat had been in since August 2002, and the zinc
on it was almost completely gone. The boat spends May thru October on a
mooring then November through the end of April at the dock for the
winter.

Thanks,

Jonathan
