Hello<br /><br />Someone told me that the lower end could crack if water is in the oil and it freezes. How likely is this? Its starting to freeze here and I really dont want to change the oil in all the motors. Whats the next best safety precaution? I have a 1946 5h Johnson that was laying around a barn for years<br />the lower end seems empty, should something be done to prevent corrosion?<br />The gas conditioner I have says run through motor is this necessary if the motors get fogged anyway?
