Please somebody explain what can cause wide oily spot around an outboard Mercury 50HP. I was checking this boat to buy. It would not start first. The owner explained that I choked it for too long and flooded the cylinders. He got it started eventually; it ran good at full speed and idle speed. When we docked the boat (motor stopped) oil spot just kept widening at the motor.
10 min at the dock left oily trail about 10? long and 2 -3? wide, stretching from the motor with the water flow. Somebody said that it is fuel leak or the motor runs too rich and that is the motor oil from exhaust. Is that correct?
