Look at the model number on the metal plate riveted to the mounting bracket. The last letter in the model number will tell you the age.

I dont see a match for that model number, They might have been made by Yamaha Motor LTD, which is not sold in USA. In 1984 when Yamaha was first sold in USA (the last letter of model number was "N") there were some motors with an "O" model number
