The raw water system should be protected by zincs. Many heat exchangers have one, mine doesn't. There is a zinc in the transmission where seawater first meets steel. There is one at the other end of the sytem where the seawater goes into the exhaust. I think this makes sense, the exhaust zinc shows some decay. I also think that the water stands there all the time, unless the system is drained. Of course, I could be wrong. But I don't change anything that seems to work.
