Thread: Mariner 9.9ML

  1. #1

    Default Mariner 9.9ML

    I have a Mariner 9.9 ML
    Code #682c L
    Ser # 368041
    I have two questions.
    What is the fuel/oil mix?
    What is the year?

    Fuel mix is 50:1 -------the motor is a YAMAHA built machine -------------I could look it up using " google " but I think it is somewhere in early 80's.

    A 682ML 368041 is a 1986 manual long shaft Yami/Mariner.
    A 682C is a code 6E7;1981;model 9.9D (Yamaha code).
    682 is also a Yamaha code for 1978 model 9.9B and C is for jet-prop.
    The "c" is kinda' confusing.
    Some manuals call for a 100:1 mix, But everyone says to use a 50:1 mix (I do).

    Thanks racerone and H. I. McDunnough for the great info.
    Next question. Do you know where I can get a users manual for the engine? May also be interested in a service manual.
