Mercury Outboard Serial Number Guide

Mercury outboard engines have a serial number tag that is located on the swivel bracket (port or starboard); or, check the instruction plate, located between the thumb screws above the steering tube. The top number on the plate is the serial number, and the number directly beneath it is the four-digit year of manufacture.
