    Sea Foam is all you need.

    Depends on what you are trying to do.
    Keep the engine clean, Seafoam.
    Stabilize fuel Sta-bil.
    Either will not work for the other.

    Sea Foam is also a stabalizer. You do not need both.

    My Yamaha dealer recommends the following:

    1) Ring Free Plus
    2) Startron from Starbrite
    3) Yamaha 2 cycle M oil

    I bought my 2000 150HP OX66 from a very conscientious new owner. He did the Ring Free and M oil, and I'm not sure what he did re fuel conditioner/stabilizer. Check out the Startron, it seems to be the next best thing after Stabil and Seafoam.

    Stabil Marine and Ringfree all the time, and with a fuel/water separater you should eliminate most fuel-related problems. My motor is a 1999 and never had a problem or had to clean the carbs, runs like brand new. If you think the additives are expensive, check the prices of carb re-builds and other fuel problems.
