Here is some information on winterizing;
2 stroke winterizing
This is what you need to do to winterize your 2 Stroke Seadoo.
1) Insert fuel stabilizer in fuel tank. Make sure you have the proper mix ratio and rock the boat to mix it with gas.
2) Plug in the water hose in the back of the boat (not on the top because you will need to pinch some hoses to do it right). Start engine and let run for 4-5 minutes to get the stabilizer in the engine.
3) Use SEA-DOO LUBE (This is what seadoo recommends, and is made for this purpose) and spray inside the air intakes for at least 30-40 seconds. What I do is I spray the lube inside until the engine dies, then I know it's in there everywhere.
4) Remove spark plugs and spray SEA-DOO LUBE inside the holes. Don't be shy to use the stuff. Screw back the plugs in.
TIP: If you use the small red tube, hold onto it so it won’t fall into the engine.
5) Remove the gray cover on the PTO and grease the shaft (you will see the grease fittings after you remove the gray cover).
6) Now for the tricky part, adding the antifreeze. Be sure to use anti freeze made for aluminum block engines. You need to follow the service manual method exactly. The service manual says to pinch hoses, and insert the fluid from the top water line. On some models you needed to pinch 4 hoses. What I did is buy vice-grips with smooth jaws ($5.00 usd each). Fill it with around 2 liters of antifreeze, un pinch one hose, put another 6 oz., wait, then remove the vice-grips. Almost all the fluid will then come out at the bottom. The idea is to mix the antifreeze with whatever water was in the cooling system, so it doesn't freeze.
A service manual is a must and will be cheaper than if you get the engines winterized, so it's a definite good investment. It has pictures and detailed instructions for just about everything you need. I don't want to say what hose to pinch because it's different for each model. I recommend you join as a “Premium Member” to get your service manual and if you still have questions you could get advice from the forum’s expert moderators.
You also need to change the oil in the Jet Pump, incase it has water in it. Ask me for information and I’ll post it for you, as it is a bit much to post here in this post.
