My oldest inflatable PFDs were made in 2002 and their CO2 cartridges were replaced in 2007. I was thinking I had to replace the CO2 bottles and was temtped to pull the rip cords but learned some things last week from other boat owners. You can save some real money by not pulling the PFD rip-cord. I learned you don't need to replace the cartridge if it weighes more than the minimum gross weight stamped on the bottle. (Because it will weigh less if any gas leaked out.) And you can test the bladder by just blowing through the mouth tube until it's firm and waiting overnight to be sure it holds the pressure. It's best to deflate the thing using an air matress compressor or a portable air compressor, cause you want to remove all the air before repacking. You do need to replace the bobbins, because they have an expiration date stamped on them. But CO2 bottles have no expiration date. Weigh them on a digital food scale and write the weight and date on a tape label each year. Replace any bottles showing corrosion or damage. Keep the bobbins up to date. Do the pressure test for 12 or 24 hrs once a year and you'll be assured your PFD will work when needed and save $ as well. So here it is January and there is 8 inches of snow on my boat and I'm home testing the PFDs and checking off one more thing that's needed before sailing season.
