Just put the I/O, V-drive and the pop-up down for winter. Drained the Heat exchanger and lower unit in the I/O, made sure anti-freeze was good in radiator. The V-drive got a trash can mixed with anti freeze in it and ran until it came out the exhaust. Pop-up gets plumbing drained and filled with potable system antifreeze. Then everything gets cleaned, covered and sit until next year. How do you winterize your v-drive. Anyone else do it with a bucket and anti-freeze?
