Motor

Your Johnson outboard model number can usually be found on the nameplate located on the motor or the mounting bracket. The nameplate should contain a model number and a serial number. The model number will identify the year and certain details of that motor.

  • Prior to 1969, Johnson model numbers were year-specific; serial numbers were used in identification. Johnsons from the 1969 to 1979 era use the last two digits of the year at the end of the model number to identify the model year; for example, a Johnson model number ending in '-4RL79' was built in 1979.
