Shaft zincs

[Gbinterim]

Recently went into a marine store to purchase shaft zincs. I noticed that the little copper bb’s were missing on the inside of the zinc. The store employee stated that the bb’s are no longer that without them there is better contact with the shaft. Am I stuck on tradition or is there something to this?

I have long bought zincs without the copper B.B. don’t think it matters one way or another.

Just clean the shaft so that the anodes are making good contact with the shaft.

Clean the shaft well, lightly sand the contact surface of the zinc, install it and tap lightly with a hammer as you tighten the screws. The zinc is soft, this will help it to conform to the shaft for better contact.

And test the connection with an ohmmeter before going back to water
