The other day, I started my 36 Stander with an electric start 17hp Kawasaki engine. Lots of smoke from the muffler, so I thought it must have tilted and the engine was clearing its throat. I let it run for a few seconds and then noticed black oil spraying out on the deck. So I shut the engine off and took it to the dealer. He said the oil probably slipped past the rings, and blew out of the bottom end of the muffler. That made sense, because the engine oil is still pretty clear and there were no other signs of leakage anywhere. Has anyone else had this happen to them?
