Hello all, I have a 1989 Merc Classic 50 which I just bought and mounted on my boat about 2 months ago. It appeared to have very low hours, less than a hundred. I have run the boat twice, both times it ran flawlessly. I parked the boat and have not been out in about 45 days. While tinkering around it yesterday, I noticed a black spot under the skag. Upon closer inspection it was a spot roughly 3 to 4 inches in diameter. I looked to see where it was coming from, it appears to be leaking from the lower unit just behind the prop. It is not a lot of oil, however I never noticed any oil from my previos motor. Is this something I should have checked out, or is this normal?? Thanks in advance.

Robert - That is normal. It is unburned oil comming out the exhaust from the fuel and common to 2 cycle motors.
