You could pump some through the flush port on the lower part of the leg, down by the lower unit. It says "flush" next to it. I personally don't bother because all the water drains back out on the entire system anyway, and should be dried out before the cold stuff hits. I have a 63 Merc 85 horse, and havn't had any freeze problems. Good luck...
