To find the year of a Johnson boat motor, locate the serial number or model number, usually found on the motor's transom bracket or powerhead. You can then reference this number against a Johnson outboard motor year chart, which can often be found online or in owner's manuals. Additionally, contacting a Johnson dealer or marine mechanic may provide assistance in identifying the year based on the serial number.
