Winterizing a 1997 Sea doo

[Gwstaudy]

I’m winterizing my 1997 Sea doo GTS today and I’m not sure how to do it or if I’ve got the right stuff. Help? I’ll attach the stuff I have below.

Most people are using biodegradable antifreeze, starting the engine and running 3 or 4 litres through it. If your using that ethyl glycol make sure you capture it, not when de winterizing .

Do not use regular antifreeze, it is toxic and should not be used for winterizing.

What antifreeze do I get then?

So just let it run through the machine and it’s good? Even thought it’ll just go through and come out?

That’s right, as it’s running through it will mix with any residual water pockets in the engine. So instead of having a half cup of water in the engine, you will have a half cup of water antifreeze mix

I used to use the pink Winter Proof antifreeze buy this year I used the blue Marine Winter Proof.

I just use 2 gallons of the Tractor Supply Travellers RV winterizing antifreeze....It has a life of 3 years and is biogradeable. It is also useable in potable water drinking systems. It is sometimes on sale at TSC for 2 gallons for $5 sometimes...otherwise about #2 gallon. Walmart may carry it too.
