    Cool 74 15hp johnson fuel mix ratio?

    74 15hp johnson fuel mix ratio? I'm guessing 50:1, but would like to be sure. This motor runs seasonal and pretty hard when used.

    50:1 using a TCW3 2 stroke outboard engine oil.

    That is near enough 1 pint in 6 gallons

    more precisely 2.56 fluid ounces per US gallon
    or 3.2 fluid ounces per UK Imperial gallon

    or 20mls per litre anywhere outside the USA

    If you are really running it hard a little extra oil will do no harm
