What year is my Johnson 70?

[spanboy]

I just got a used boat with a Jonhson outboard engine model J70ELCIM. I will like to find out what year it is? Would anyone know or tell me how I can go about finding it out?<br /><br />Thanks.<br /><br />------------------<br />Spanboy

1981. CI is 81 from the word "introduces" where i=1, n=2, t=3 and so on.<br /><br />Good luck!
