About 6 years ago, I had the raw water pumps on my Perkins 6.635 engines replaced. I now have about 300 total hours on the engines.
During my recent cruise, I noted there is now prominent oxidation (copper petina) on the exterior of the raw water pumps, but they are working well. Movement of raw water through the cooling system has been fine and they are not leaking. The seal cap is intact.
Should I do anything with this oxidation? Should I strip this petina off? What would work for this?
Thanks
