Bill , Might the gasket fit over the threaded opening and rest on top of the reservoir and the cap tighten down on top of it ,I see black marks on the bottom of the cap as though it had been in contact with the rubber gasket. Not the typical gasket/cap contact point , but may be. Does the gasket fit over the threaded part of the reservoir ? The diameter looks about right .

Subject: [AmelYachtOwners] What is this black gasket

See the black gasket in the attached picture. It was found inside the C-drive oil reservoir. At first glance I thought it was the gasket for the top, but obviously not. It is too large. 

I think I have seen this gasket before.

Any help would be appreciated. 

Best,
