Exhaust - 2 stroke
 

I have been noticing for years with several different outboards that while at idle on the trailer there is a fair amout of oil puddling up on the ground with the water from the exhaust. I realize this is standard, and depending on the size of the engine plays a factor but how much is "normal." My 225EFI Merc seems to have a fair amount.

My 225 eTEC does not have any oil leakage via the exhaust. In the past I had a 115SPL that used to drip a significant amount and in the double oil break in you could actually see oil running down the skeg. I always ran this motor a bit rich so I assumed thats why there was some excess. I also run a 250 mecury and short of a very little did not have oil leakage.

Do you premix in your tank or is it oil injected? It could be a result of your mixture.

I am not a mechanic and have no idea if what you are seeing is normal, but I figured I would give you some thoughts on what I have seen in the past.

Totally normal.

Makes you wonder just how much of that oil is in the water after all the years of outboards being in service.
