oil leaking from outboard?

[a12seccrx]

Hauled the boat to storage the other day. When we tipped the 15hp Johnson outboard to the "up" locked position, and turned it to the side, what looked like a little oil leaked out of the port that water flows out of for the cooling system. I have little to no knowledge of the construction of boat motors, so I was just wondering if anyone could tell me what this oil leak was caused by?

Is this a 2-stroke? If so it's probably unburned 2-stroke oil in the exaust. This is normal in a motor that is burning a tad bit rich and/or is used for trolling at low speeds a lot, and one of the main reasons carbureted 2-strokes are getting banned everywhere.

Yes, it's a 2-stroke and we use it for trolling. Thanks for the input! I don't really know a whole lot about boat motors so I got a little nervous when I saw that.
