Anybody have any idea where to get a replacement oil drain plug for a Merc 9.9 4 stroke, year is 1997, s/n is OH009833. The drain plug part number, as near as I can tell is 12-825769-1. There is also something called a damper listed, p/n 825768. The one that was in the engine has come apart. I've looked all over with no success at all. I've ordered the part on-line, only to have the part back ordered, or the order cancelled on me. Very frustrating.
