That's odd.... My 1979 Perkins 6.354's both have pencil zincs in the heat exchangers...and they are 135 NA's...

Greetings,
Mr. RC. Please tell me more about the ceramic coating of your cooler. I'm assuming your water cooled exhaust manifold. If not, what? Advantages? Cost? Reason?
Should only have the pencils on the raw water side. The antifreeze protects the fresh water side.
Opps, I call the engine coolant with antifreeze the fresh water side. You are talking fresh water as in a lake. Then you are looking for Magnesium Anodes.
Correct, the marina parts dept. couldn't find them from Westerbeke, I don't know how many other suppliers if any they tried.
This may be a silly idea and if it is somebody please call me on it. I recall a thread recently discussing hull anodes where someone gave a link to an online source for them. Perhaps fstbttms was the one whom posted it.
Would a supplier of hull anodes also source them for this application?

Years ago, a prominent marine shop here changed my oil and put 5 gal of oil in each of my engines (Perkins says they should hold 2.5 gal), and I saw it on the invoice. Their mechanic swore up and down that he knew these engines in and out, because of the oil cooling system they need more oil and you had to check the oil with the engines idling. Finally we called the perkins distributer to get it straightened out. They ended up pumping 2.5 gals out of each engine and no you don't check them idling.

My. Volvo tmd41As have zincs in the HE and oil coolers. Perhaps that's why they are sooo reliable and every one wishes they had volvos
