    50:1 Premix ratio!!

    The jet ski has been converted to Premix and been using 50:1 ratio. Is that ratio too high for a 780SL? What do you guys usually run?

    32:1 would be the normally recommended fuel: oil ratio during top end break-in.

    40:1 is the common fuel: oil pre-mix ratio for normal recreational operation.

    Are you using a high quality 2-stroke oil?

    Doesn't matter what units

    It is a ratio and doesn't matter, as long as the oil is in the same units as the gas.
