Cummins Aftercooler zinc; P/N and source?

[NorthernFocus]

Does anybody have a source and part number for the zinc in the engine(aftercooler) in the cummins 150hp? It is the only zinc listed in the engine manual. Takes a 22mm metric wrench to remove the brass plug that holds the zinc.

Dan,
According to the Mercruiser parts manual the part number is 879194217. A search found the best price at BoatZincs.com. Now here comes the strange part, it is found under the Yanmar listing. Go to BoatZincs home page, select Engine anodes, Yanmar, scroll down to 120650-13420 and open the product specs. Shows Cummins QSD series and reading last bullet calls as replacement for Mercury Part 879194217. Be worth a call to confirm.
