It's correct that the little air pump does not get all the water out. My boat came with a 496 and I lost a heat exchanger one winter. A used one cost $400. After that I started unhooking hoses and blowing the water out with air pressure. The symptom of the bad heat exchanger was that the antifreeze was dropping and coming out the exhaust while running on the hose. He may have gotten lucky if day temps were above freezing. Hopefully he has now properly drained the raw water side and he will find out in the spring by running it on a hose.

Man that hurts! I used to live in Miami so I know what I am missing. I could fly down for a week, but the trouble with that is I would have to come back and that would just make things worse.

I do want to come down for the boat show in Feb. however.

It takes about 10 min to use the little pump on the front of the motor and drain the exhaust... I would definitely check the heat exchanger! I would say it is going to have some issues

Ice, under ideal conditions can generate about 114ksi of force. That's well beyond most steels yield tensile and probably past the ultimate tensile as well.

In other words, don't mess with physics.

Just thought of something else useful. Ditch the little blue pump. It is a pain in the rear end. Go to Advance and pickup a $15 cigarette lighter tire pump. Keep it in the boat and hook it up when you are ready to winterize. Turn it on and multi task... Will take less than 5 minutes and prevents false readings/you might think its empty when its not. Sometimes as the little blue poppits get old they get sticky and fussy.

When I was in Georgia we used the boat during the winter for an occasional booze cruise and this made it fast & easy. Later I came up with reptile heaters that were even easier but the cigarette lighter pump worked well.

The little blue pump, or what ever you use to pump up the system; does not REPLACE the water as one might think.

It just charges a closed system that opens two drain actuators. You can use a 12V Air Compressor, an air tank, or a bicycle pump. There is an automatic air pressure purge valve.
