HELP!! Winterizing Fresh Water System + A/C

[DBenja4148]

My boat: Chaparral 260 Cruiser 2003 49 hours<br /> Volvo Penta 320hp GXi 5.7<br /><br />Can anyone provide suggestions on how to winterize my hot and cold fresh water system and A/C which the dealer wants to charge $40.00 each. Trying to save some money since they will do the engine and stern drive for $300.00. I will also try to winterize the marine head which shouldn't be too tough. Thanks for your advise

I'm sure 15 people will give you 15 variations but here is what I do,<br />drain freshwater tank<br />drain hot water tank<br />remove hot and cold connections from hot water tank and join together (small pipe with 2 male ends on it. I do this so I don't have to fill the hot water tank with antifreeze.<br />Put pink plumbing antifreeze in fresh water tank and turn on pump, make sure you get pink stuff out of every tap.<br />For A/C, disconnect water hose from seacock and put into jug of antifreeze (has to be low because pump is not self priming) and turn on A/C, wait for pink stuff to come out through hull.<br />For the head, after it's pumped out I disconnect the water line from the seacock and put it into a jug of pink stuff and pump it until it's empty, this way the antifreeze goes through the lines, the head and is in the holding tank until next spring.
