Looking for a mechanically equivalent yamaha - Mariner 9.9

[yakoun]

Hi all, hoping to get a source of parts - preferably yamaha parts, for this little 9.9. As such, really wanting to see if there is a mechanically equivalent yamaha outboard that I can look up. Can anyone help me out? 682CS 018544 I think it may be a 1980 model.

What markings do you see on the carburetor and the CDI box?

Looks to be equivalent to one of these four Yamaha models.
