    Default Using In-Floor Tank for Oil/Gas 2 stroke mix

    Hi all,
    I just bought a used Lund Alaskan 1600 SS. It has a 20 gallon in floor gas tank. It used to have a 4 stroke Honda, but I only bought the boat and trailer because owner sold the 4 stroke separately.
    I am going to put a 1975 Johnson 2 stroke 75hp on it.

    Can I use the existing 20 gallon gas tank and mix the 2 stroke oil required?

    Do you think it will provide a good uniform oil/gas mix?

    Whenever I use the small 5 gallon tanks, I add the oil, then fuel and then shake and invert the tank by hand to ensure good oil to gas mixing.

    Will the oil separate out from the gas over time?

    Thanks for all your input,
    wascal

    Just use it. Mix your fuel to the right ratio and go. Many boats are configured like this.

    Remove gas level sender and check to see if tank clean and not rusted inside first. Replace sender gasket.
