I have a 2002 Velocity with a 496 HO that came equiped with a water drain system - minus the hand pump. Living in Michigan, I have always used antifreeze in the closed cooling system. Was curious if anyone else might have one on there boat and if you use it espicailly in the colder areas where the temps tend to drop below zero?

Do a search. This has been discussed before.
Using the air/water drain system will get you through a quick cold snap late in the season, but it is NOT for full winterization.
You need to do a full winterization with antifreeze and the whole kaboodle for long term winter storage.

I just use the hand pump and unsrew the blue wing nuts on the sea pump to get me through until the marina does an actual winterization. I would like to do it myself in the future and have 5 gals of pink stuff run through the supply hose to the sea pump. Run it through while hot and it should be good. I dont think they do anything to the motor side as long as the antifreeze tests good.

The first 2 seasons I simply pumped the water out and pulled the blue plugs on the water pump and fuel cooler. Never had a problem (I live in Bloomington, IL. and it gets pretty cold here). Last year I ran antifreeze through the system. The biggest concern with just using the pump is if you don't get all the water out of the heat exchanger, you can damage it. My boat is proof you can get away without adding antifreeze but why risk it?
