    Walked out to my boat today and saw this oil leak on the transom directly under the outdrive. I can wrench on cars but boats are kinda new to me. Anyone know what’s causing it? Easy fix or ? Btw it’s and mercruiser Engine with alpha 1 gen 1 outdrive.

    Not sure if you found it or not but I think some exhaust comes from that hole. It’s hard to say from your pictures but I think you’re going to have to continue your investigation until you pin it down. In 50 years of boating I’ve never seen aN oil leak from there. I would see if it’s wet anywhere on the transom plate inside the boat. Let me know what you find.
