Hi,

I have owned a 2003 F15A Yamaha 4 stroke stroke engine for the last year. I've not had any issues with it.....until today.

I have just serviced the engine, changing the engine oil, gear oil, spark plugs, oil filter and fuel filter.

I was out in my boat today and it appeared to run perfectly.

On returning I saw a black grease/oil was seeping from the upper exhaust and the exhaust at the rear of the propeller (I am assuming an exhaust is located there also?)

It appears I have put too much engine oil into the tank, could this be the cause of the black stuff?

I will drain some engine oil regardless but I was wondering if this is likely to be the cause of the problem or if something more serious could be causing this?

Thanks

Craig

If you just changed your oil, then it shouldn't be black.
