Hi Chuck- I had exactly the same experience after a May launch. The shaft zincs
looked fine at that time, so I left them and put a new bullet on the prop.

I use silicone dielectric (non-conducting) grease all the time on
electrical components such as battery terminals and spark plugs. I think
the idea is that it eliminates water/air/chemical intrusion and subsequent
corrosion. The metal contacts poke through the grease and make "contact".

If it is not brackish from the ocean then the zinc is being used up to
protect the prop from corrosion for another reason...is the water mostly
pure or are there a lot of industrial or agricultural pollutants in it?

Dwight, I am on the very northern end of the Chesapeake Bay - it is FRESH . I
am located on the Bohemia River. I replace the zinc each year only because I
want to start the year with a new zinc, there is still at least 50% of the zinc
still available. The idea of using a grease is interesting, I

I was on the hard one winter next to a retired corrosion consultant and ex Phd
metallurgy prof from MIT. He insisted that to make a good connection between
the zinc and the shaft, you should apply a lubricant to both before bolting on
the zinc. I know most lubricants are dielectrics, and are not
prop, which is the main reason we use sacrificial zincs on our boats.to
protect the copper alloy prop

I have a martec folding prop and install their bullet shaped zinc each spring,
they recommend the zinc be installed next to the strut within 1/4" to 3/8".
The zinc lasts me the entire year, I sail on the Upper Chesapeake Bay which is
fresh water.

Right or wrong here's how I install shaft zincs on Touche'.
1. Use a good brand of zinc with a copper contact. I like Camp zincs
2. Use emery cloth to make shaft bright
3. Apply a small amount of TefGel to the copper contac
Another option to help seat the zinc on the shaft is to use a "C" clamp rather
than striking the zinc with a hammer. You are less likely to damage something
using a clamp.

I still wack the zincs as Dennis decribed and I use lock tite on the nuts.
I use 2 zincs and from early June to early Oct this year both were used up

Tef Gel is even okay to use on the contacts of switch gear relays. It
prevents corrosion without creating electrical resistance. I have no
idea how that works, but that's what the literature says. It does sound
counter-intuitive, but it's perfectly okay.

Dennis, why would you put an insulating material (Tef Gel) between the two
elements that have to have good electrical contact? Seems a little
counterintuitive to me.
I stopped whacking the zincs with a hammer a few years ago and haven't had
any problems with zincs not staying on/bonded.
