    Trim pump

    I have a oildyne trim pump on a 300 promax.
    It won't trim up under power. Let off the gas and it is just fine. I was using it instead of the Mercury pump because it is 3 times as fast.
    Any ideas?

    Good deal. Easy for anyone to check. Either I was very lucky or mid to late 90's 260 mids worked either way! Mike.
