Resealing a '83 70hp Evinrude and I've gotten to the Shift Shaft cover. There appears to be an o-ring in the hole under the brass bushing. How on God's green earth are you supposed to change that? I could probably get the old one out but I don't see anyway to get the new one in. ![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
