I had a tool once, but too much zinc made it corrode away.

Are you sure you just didn't lubricate it often enough?

Never forget them. Do something to prevent it from happening again.

No....lack of use eliminates the need for lubrication.
It appears this thread has run it's course. I'm off to line my hull with Zinc!

The gizmo you refer to is a silver/silver-chloride electrode, which is used to measure the stray currents affecting your boat. I've used them. They work well, but they are a bit pricey. If you are experiencing abnormal wear on your zincs, or have issues with blisters on metal hulls, or problems with any of the metal components underwater,

-and-

you understand the concepts involved with electrical currents, galvanic corrosion and electrolysis, then you may find the Ag/AgCL probe a benefit.
It's very useful in tracking down an elusive bonding wire or help confirm your system is well protected.

Re: Too much zinc?

Thanks for the correction of a couple of hundred years. Remembered the principle, not the year. Thanks again for the correction!!!
