You should find the serial number between the thumbscrews of the transom mount. I'd suggest you replace the water pump impeller and change the LU oil, then fire it up before you do the carb, but that's just me. If all the gas was run out of it, the carb might be just fine.<br /><br />Parts diagrams here:<br /> http://www.mercruiserparts.com/selectModels2.asp?type_id=MERC <br /><br />Parts and other info here:<br /><br />oldmercs.com
