Now that our E38 is back in the water, several neighbors at the docks have stopped by and asked if checked or replaced the zinc in the heat exchanger? From their expression and reaction, I guess I must have looked like my german shepherd with my tilted head and confused look when I said 'huh'? So, that said, went looking for this mysterious thing that several folks have now mentioned. Since this is my first experience with owning a sailboat, or diesel engine, I'm not entirely sure what I'm looking for, so if someone could possibly describe where on/in the heat exchanger I might find this zinc, it would be much appreciated. When I do find the zinc, am I going to have to drain the coolant, or whatever is in the heat exchanger, in order to change the zinc, or will I be able to do this without all the mess? Again, thanks in advance for everyone's feedback. By the way, this E38 has a Universal 32, 5432, if that helps.
