Marelon is a good substitute for bronze seacocks. It is unaffected by electrolysis- so there is no need for a bonding wire. Also, corrosion of any kind is not a problem. A light lube from time-to-time is all the service needed.

I recently bought a J105 with these Seacocks. It seems that the previous owners did not operated the seacocks for years. I currently have the boat in freash water and would like to lubricate the seacocks while the boat ius in the water. Is this possible? I also have had a problem with one of the seacocks. While I was opening it, I end up with the handle in my hand. The seacock remained closed. How can I address this problem?
