Should only have the pencils on the raw water side. The antifreeze protects the fresh water side.

Yes that's why I was looking for ones suitable for freshwater.

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?

Don't know which engines you have Larry but my Perkins HT6-354 manual says the oil should be checked at idle due to the dry/wet/scavenger pump sump arrangement.

I don't have any engine zincs. I don't have any seawater on/in my engine. And that is no accident.

Zincs on the sea water side of a cooler makes sense to me - despite of what the manufacturer says.

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

Thanks for the link! After seeing how the one on my port engine failed I'm going to try these out. I'm intrigued by the "Secure Core"

Both are soft and usually to long, so they can be cut off and easy re thread. I would not rethread the plug!

There was a very long discussion a couple weeks ago about anodes and it was finally ended for fresh water zinc is OK, but magnesium is a scoash/tad better. Zinc for brackish and salt where they last at least a year. Aluminum for salt in hot marinas where zinc do not last.

Zincs last as long as they may. Some boats, some applications, some places.....some a year...some a couple weeks.

So far on this trip of mine...the Lehman zincs need replacement about every 2 -3 weeks plus around 50 hrs running time.
