To accurately determine the year of your Johnson outboard motor, it's essential to decode the serial or model number, which contains the year information. Here’s a step-by-step guide on how to identify the year:
-
Locate the Serial Number: The serial number can be found on the outboard motor's nameplate, typically mounted on the motor or the mounting bracket. For older models, check for a silver core plug on top of the powerhead where the serial number may be stamped.
-
Decode the Serial Number (1980-Present): Johnson outboards from 1980 onwards use a simple coding system within the serial number. The code is based on the word INTRODUCES, where each letter corresponds to a number (I=1, N=2, T=3, R=4, O=5, D=6, U=7, C=8, E=9, S=0). For instance, if the model number contains 'EE', the corresponding year would be 1999.
-
Model Number (1969-1979): During this period, the year of manufacture is directly indicated in the model number. For example, a model number containing '76' indicates the year 1976.
-
Pre-1969 Models: For Johnson outboards manufactured before 1969, determining the year can be more challenging. In such cases, you'll need to consult a Johnson serial number year chart or seek assistance from a marine mechanic or professional.
-
Commercial Models: If you have a commercial Johnson outboard, you might need to reference a specific chart for commercial models to determine the year based on the serial number.
By following these steps and decoding the serial or model number, you can effectively determine the manufacture year of your Johnson outboard motor. This information is crucial for proper maintenance, ordering parts, and understanding the history of your outboard.
