    How to find your serial number on your Mercury outboard

    Seems to be asked quite a bit so I thought I'd help a little in this regard. Don or Sherm might jump in on this but pictures speak a thousand words they say. Most know the most logical place is a plate on the motor

    First one is more of a distance shot to give you an idea - most I know are on the starboard side of the motor



    and a close up view of what that tag could look like (info on tag may vary)



    and then if you can't find that - look for the welsh plug as it'll be stamped on it



    Remember its Digit, Letter, 6 more Digits (except older motors) and rebuilt motor may not have the serial number.

    Remember - Mercury DOES NOT go by year but by serial number when it comes to ordering parts etc.

    SOMEWHERE on the powerhead (location varies). If you need further assistance locating your serial number, I would suggest opening a separate topic for your engine.
