I have a Mercury 9.8 hp 110 outboard. I'm trying to verify the s/n and year made in order to obtain the proper service manual. I found a raised number cast into the engine block on the rear starboard side of the engine. The number is 8372756. That number doesn't seem to fit within the s/n ranges offered on line for matching s/n's to years made. Can you help me either find the correct s/n if this number is wrong or identify the year this engine was made. I found a number etched into the motor cover on inside just below the cover gasket (amature job of etching). Not sure what this number means but perhaps it can help answer my question. The number is: M600 745 275 856.
