I have a 1993 Mercury 150 hp XRi that I just bought along with a boat. I have been trying to find a serial number somewhere on the engine so I can get my Ohio paperwork done. I can't find a tag, a plate, a stamping or ANYTHING on this engine. I can't even find a place where one may have been.<br /><br /> I have asked several people and no one seems to be able to tell me where it is. I have looked on new engines and it is a tag one the starboard side of the tilt bracket. I looked on mine; nothing. I see a stamping on the underside of the bracket but it looks like a part # or manufacturer's code. I was told that the Merc serial numbers are 8 digit numbers- are there letters in there or just numbers?<br /><br /> I can't get this engine titled until I get the serial number. Help!<br /><br />UFM82
