Extra oil seal on Mercruiser MC-1 outdrive?

[auscarter12]

Changing the gimbal bearing on my 1973 MC-1 outdrive. After pulling the bearing and oil seal, I discovered a second oil seal behind the first one. Is this normal? I've looked at exploded view drawings in both of my Mercruiser manuals and don't see anything about having 2 oil seals. I was able to get a part number off of it: CR 26-36143. Looked it up and it is infact a Mercruiser oil seal, but I get the feeling it may be an old style? I'm attaching a picture as well. Should I remove this second oil seal before putting on the new oil seal and bearing, or should I leave it?

Thanks for all the help!

Not an oil seal, if anything a grease seal
