"I have a 2002 Yamaha 225 4 stroke, approx 700 hrs, started noticing a fine oil slick caused by oil coming from where water come out (tell tail, lower end outlets etc) when flushing.
Sure this must be a sign of something gone wrong. Engine oil looks fine and lower end oil has no sign of water. Where could this oil be getting into the cooling system from?"
