    I have a 1994 75 HP Mercury. When I winterize the motor, I disconnect the fuel line and run the carburetors dry.

    For some reason, as it sits, the oil drains out of the oil tank.

    Any reason for this?

    Drains as in "Leaks" out? I assume your oil tank is on the motor correct? Where does the oil go when it drains?

    It appears to be draining through the carburetors. The tank is new, I know it's not leaking.

    There must be a check valve or something in the carbs to prevent this because the gas would be leaking out as well. I'd look very closely at the feeder oil line to make sure it is not leaking somewhere near the carbs and making it look like it is coming from them.

    The fuel line was disconnected all winter. Would the oil still fill up the carburetors?

    why are you disconnecting the fuel line?with good gas treatment and running the motor on the muffs long enough to get it into the carbs you will have no trouble. at least thats what i have done the last 20+ years.
