PLEASE NOTE: leading zeroes are not relevant, e.g. '0B123456' is the same as 'B123456' in the listing.
However, later model serial will begin with a '1' or higher in pace of the '0'; those ARE significant .
US-made Mariner motors are identical with Mercury serial number ranges and use these same charts.
The serial number format is the same.
Japanese Mariner motors have a totally different serial number scheme, e.g. '6A3-S-123456'
We currently do not have those here, but are largely useless. These motors do not have any consistent year-to-serial scheme.
Mercury ceased publishing this information after the 1996 model year. There is no way to find the model year of motors with significantly higher
serial numbers than listed in these guides. There is NO serial-to-year cross-reference chart for 1997 and later motors.
Mercury has never really used model years for much of anything other than 'sales tools' in dealerships.
We WILL need your serial number to look up correct parts.
The Serial Number. If your Mercury outboard is a 2006 model, or newer, you can use the online Mercury Parts Catalog to look up the model year.
