  • oil leak

    Hi...I have a '85 15hp Johnson and have an oil leak or seep from a 5/16" hole in the casting on the front port side of the lower unit housing just above the prop shaft...whats the problem...please

    Probably nothing. It is a two-stroke motor. There is going to be some oil residue in the exhaust passage down through the lower unit. Once the motor is out of the water after being used, it is normal for some residue to leak out of the exhaust drains. Black in color.

        Beats me. I've never seen that before. Wish I could actually examine it.
