If I had the full number I'd be able to tell you.
Usually, the year code is the last two digits or the last 2nd and 3rd digits.
Here is most of the info you will need.
Your engine will have a model number on it, usually between 8 to 12 digits.
Example: V J 120 T L CE A
Each digit reveals important information for your specific engine.
The year is revealed by using an acronym called "INTRODUCES".
The Model Number Digits identify
STYLE - DESIGN FEATURES - SHAFT LENGTH - YEAR BUILT - SUFFIX/MODEL RUN.
Where to find your model number:
Johnson/Evinrude Outboards:
The model number tag is located on the top outside edge of the CLAMP BRACKET; or, on top of the SWIVEL BRACKET HOUSING (port or starboard). It's usually a metal tag or a sticker. Often there is a quarter size silver piece with numbers stamped on it.
If you're still unable to find a model number on your engine, (sometimes will be worn off or scratched off), there is a silver core plug on top of powerhead with model and serial # or p/n on power pack can help with determining the year.
Also check on the welsh plug (freeze plug) on the block (power head) for numbers/letters. (If powerhead has been rebuilt or replaced this probably won't help you. (Will only reveal the part number of the new, not original powerhead.
