How to Identify a 1985 Johnson Outboard

Johnson Motors produces a series of outboard engines for boats. These engines range in size from very small 2-horsepower models to large 115-horsepower engines. Johnson has been making engines for decades and includes a date stamp in the engine's serial number code. Identifying a Johnson Outboard from 1985 is a matter of finding the stamp and reading the code, as well as seeing the Johnson label on the cowling.

• 1

  Look at the sides of the outboard engine in question to find the large "Johnson" marking. Johnson engines include the Johnson label on both sides of the outboard cowling -- the cover that goes over the engine.

• 2

  Pop the cowling locks open. Push the edge mechanisms up and off the lip of the engine to pop them off, then lift off the cowling to expose the engine.

• 3

  Spray some degreaser onto the rag and wipe off the metal serial number plate found toward the back of the engine.

• 4

  Look for a "C" and an "O", the second and third characters from the end of the model serial number stamp code. The "C" stands for 8 and the "O" for 5, indicating it is a 1985. The last number is the model run.
