I had my boat out of the water last week, and I noticed a small oil spot (3" diameter) that had appeared under the skegg of one of my outboards overnight. I have determined that the oil is not coming from the prop shaft seal or any other part of the lower unit. It appears to be draining down from the powerhead via the exhaust.<br /><br />Something thats probably related is that when this engine is tilted up for a period (2-3 days), I have to lower the engine and wait 5 or 10 minutes before the engine will start. If I don't, and the engine finally does start, there is so much white/light gray smoke I can't even see the engine.<br /><br />Any thoughts on why the oil is accumulating in the engine?<br /><br />Thanks, Michaelb
