Identifying Model Year

Greetings! I just purchased a used Mercury Mariner in very good condition. The plate on the motor identifies it as a Mariner 9.9CE 682C550283. Does anyone know what year this motor is? I would like to source a user manual for it if possible. Many thanks!
 
This is a Yamaha built (for Merc) Mariner - so "mechanically" a Yamaha although there is a Seloc's manual for Mariners (repairs), I have no idea where you might find a "users manual" - "fleabay" maybe??

I will break down all your (numbers).

9.9 - horsepower
C - "C" model Mariner
E - Electric Start (from factory)

682 - Yamaha designator making it "mechanically" a 1978 "B" model Yamaha
C - tiller or remote control (would have been buyers choice?)
550283 - 1978 year of manufacture
 
Thank you very much for the detailed breakdown! I hope being built by Yamaha is a good thing. The motor is very clean and started with the second pull. I will look into picking up the Seloc's manual to keep up with maintenance.
