Hi,

I just purchased a used 4 hp, 2-cycle Mariner 4M, year unknown and
without manual. I've some basic questions. The marking on the engine
says 6E0 S 105164 and Made in Japan.

1. what info can I derived from this (make of year)?
2. how can i find out its year. (I'd like to get a manual).
3. how much 2-cycle oil should I add to 1 gal. of gas?
4. can someone point me to some basic outboard maintaince resources?

thanks.
