hey guys, today when I was flushing my motor with the cover off I noticed that it is leaking water out of the what I want to call the timing cover, It is a 75 merc 650, and its coming out of the cover that says spark stop, throttle stop etc, anyone have any idea whats going on and what I should replace and if there is an immediate damage that is possible, there is still good flow coming out of the tell tale.?
