Last night I was winterizing my boat. After running it for 15-20 min to a temp of 150 degrees. I started by draining the exhaust manifolds. There was almost no water that came out and it was cold. Is this okay or do I need to run until the temp goes to 170 degrees? I ran the motor to run the fogging oil and stabalizer through and did not change the oil. Do you need to run the motor at all to just drain everything?
