"While underway my 2003 Yamaha
"While underway my 2003 Yamaha 4-stroke F115 oil pressure warning light went off and I discovered oil leaking from the drain plug and the engine oil was milky. Is it likely that a loose or leaking oil drain plug could have allowed sufficient water back into the engine oil to turn it milky? If this is the problem what do I do to flush the engine? Simply drain the oil, replace the oil filter, use a new drain plug gasket, tighten correctly and hope for the best?"
