Ok so I uncovered the boat today and lowered the motor down and lower unit oil started coming out of my grooved hole thing (i believe its the water intake?) on the lower unit. Nice clean oil but a decent amount of it. So i popped the screws out and very very small amount of water (less then teaspoon, maybe half teaspoon) came out followed by half clean oil mixed with a black oil. I recently replaced the shaft bearing cage and had some welding done to the lower but its been good since. What is the black stuff and why did oil come out of the drain holes. I have some pictures to show the leaks. But clearly it took in some water at some point. Ive been out 4 times since the repair and it was good every time I checked??? should I be keeping the motor in the down position when stored? anyways just looking for a solution. thanks for looking and its a 1975 555HG
