Dezincification Photo
I hear the subject of dissimilar metals come up a lot and also the term dezincification. Lots of folks just go "huh?" when they hear that word. I've also heard others try to describe what to look for so here it is..
This is what dezincification actually looks like on a piece of brass. This is one of the end caps from my Westerbeke heat exchanger. You really need to clean the metal to see signs of dezincification.
Change your zincs regularly, especially in the engine zinc!!
