    Or a tough journey to the Yamaha USA parts catalogs to see that a 40ELH model is from 1987.

    It is very tough. Takes a walk to the other side of the motor and the month and year of manufacture will be on another sticker.

    Yamaha 80 2 stroke no oil injection

    In what country are you and/or the motor located? Yamaha USA offered a C80TLRV in 1997 only. Other countries around the world could have been offered a 80 HP two stroke without oil injection.

    Yamaha 80 2 stroke no oil injection

    Yamaha 50hp Carb Orings too small on Silencer facing side

    I looked at all of the carburetted F50's and the same gasket is shown for all of them. Don't think it is a part number error.
