Hey everyone,

First time user and poster. I'd like to find out the year (production) and the right oil ratio for my outboard please.

Mariner 5M
6E3 S 10994
Made in Japan, and it has Yamaha Badging on what i think is the head.

Also, what is the oil ratio, and is standard 91 octane unleaded ok?
Thanks heaps, Tinny Boy
