I read an answer from (Don.S) on a question about serial numbers and what year the running gear was built. It was the last 4 numbers of serial number to determine date built. Is this true with Mercruiser running gear? Im asking because I own a 1993 Bluewater boat with a 4.3LX Merc. The transom #0f090894 (aug 1994 ??), engine #0f068457, drive #0f102057. I e-mailed merc and he said it was 1993 running gear. Just checking to see if the transom is a 1994??? Thank You
