" Sounds like you might be burning oil, although I would imagine you would see a lot more blue smoke than "just a little". What you might be seeing is a form of smoke condensate dripping down from the exhaust. This is smoke particles (basically soot) that get mixed with water and form an inky black liquid. If this sounds like what it looks like, and the oil level on the engine is not going down very fast, I wouldn't worry too much about it. Generally excessive oil consumption is only a serious problem if it becomes hard to maintain a proper oil level in the engine, the smoke is unbearable (especially when motoring downwind), or just too embarassing! I don't think they issue citations for excessive smoke on boats just yet.

Please advise, Thanks Randy Clouse
