    The upper plug…which needed to have my compressor fitting really tight to eliminate bubbles…had a plug with a white nylon washer in good condition.

    The lower plug (no bubbles, not leaking for the test…but I opened it to drain the gearcase and re-seated it for the test, so that’s not necessarily indicative that it was sealed while boating)…it has the remnants of a fiber washer mashed badly into the gearcase opening and will require some surgery to get it all cleaned out.

    Any thoughts on my previous question about gear oil to use?
