Antifreeze Exhaust Flush for Sea-Doo

[3ftDeep]

In this how-to video we show you how we protect our exhaust system from the threat of a freezing winter by pumping RV antifreeze through it. Performed on a Sea-Doo 2005 GTX 185 jet ski, this procedure is not endorsed by Sea-Doo (so don't look for it in the Service Manual). Perform at your own risk!

If you want to spend extra time pumping Anti-freeze, it's completely up to you. But I must say, none of my seadoos exhaust pipes got frozen without it.

Why fill it with AF then blow it out?

The idea is to have as little fluid in there as possible, and whatever fluid is in there to have a low freezing point. It doesn't get too cold here out west, but in places where it gets very cold during the winter and the ski is stored outside, better safe than sorry.
