Re: Why doesn't my Perkins have any Zincs?
My 4108 has no zinc in the heat exchanger. It has been explained to me that the rubber end caps on the tube stack isolates the brass/bronze tubestack from the surrounding metal. Correct me if I'm wrong?
This makes sense! Thanks for that revelation!
It also makes sense as to why all my custom copper tubing and my bronze raw water pump and strainer are turning to green powder... Hmmm.... Methinks I should zinc the bits before the rubber caps.
Perhaps a stupid idea, but what about just dropping a zinc into the sea water strainer basket? Something like a half-eaten shaft collar zinc? Wouldn't satisfy the anal engineer in me, but it would satisfy the "get-er-done" part of my brain.
I have a sauna on my boat, therefore I win.
