After seeing all the posts about winterizing boats, I was wondering how many of you guys have closed cooling and or fresh water flush outs, the closed system can really extend your boating season and of course both are needed if you boat in salt water.

My jet is closed cooling.

For flush out I just pump RV antifreeze through the water dumps.

I'm guessing most boats don't have closed systems
