Mercury Logo & Cowl Decal Identification Chart

This Mercury Marine and Mariner Outboard Decal Identification Chart can help identify the model year of an older engine by the decal design and colors on the cowl. The chart includes Kiekhaefer and Merc logos years including 1939-1945, 1946-1954, 1955-1970, 1971-1977, 1978-1998, 1999-2005, 1990–1993, and 1994–2000.

You can also find the serial number and model number on an ID tag on the mounting bracket, or in some cases on an engine block freeze plug. The latest serial number labels display a 2-digit number in a box at the lower right portion of the label. These digits coincide with the last two digits of the year in which the outboard was manufactured.

For Mercury 2.5 Liters, please see our info post with block identifications for all the double letter stamps such as AA, BB, CC, EE, FF, F, NN, SS, PP, LL, etc.
