How to date motors

[dew2]

I am looking at a Johnson 20HP mod#J20CRCSA. I look online and I find things saying its a 1973 but nowhere can I find a motor with that Mod#. Is there a site where I can type in the mod # and get the year model?? I have also found statements saying it a 1980 but again at BRP no such thing for 1980. I'm stumped and need a way to determine years with the modle #. Thanks in advance

It is a 1980; the"c" is the 8th letter and the "s" is the 10th letter in the word INTRODUCES which is the code used to identify the year.

And I was going to say to start with candy and flowers.

The CR means it's a Canadian de-rated rope start model
