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 conductors, but he insisted. I tried it, and he was correct. It did improve the conductivity between the zinc and the shaft. I'm assuming the the lubricant allows you to get a better contact because of the lubricity, and not the conductive properties of the lube. I used a lithium based water pump grease, but he said most any grease would do.
This all sounded like hokum to me, but considering the source, I tried it. He also tought me some thing about protecting my centerboard cable, and other parts of the CB system.
