Winterizing?

[tjones823]

What’s the correct way to winterize my 97 SeaDoo for the winter?

I’ve gotten the pink marine antifreeze, I know you have to flush engine with hose after last ride then get the excess water out by reving a few time but not over 15 seconds.

What’s the best/easiest way to pump the anti freeze thru my system?

You can get a cheap drill powered pump at your local hardware store. Start the ski and pump two containers of the pink antifreeze into the flush port. Then spray fogging oil into the carbs until the engine dies. I would also change your jet pump oil just in case there is water intrusion, don't want it to freeze. Make sure the ski is running when pumping antifrezze!

If you look in the factory service manual its all gravity fed, it takes about a 1/2 gallon to do it the way thru manual tells you. And you don't have to buy any thing other than the antifreeze and fogging oil. You really should put stabil in the gas too. And as was mentioned, change the pump oil. But you can literally winterize a ski in 15 minutes. I made a few threads but they are for the 787 engines not the 720. But Google for the seadoo service manual and it will explain it the factory way.

How do you change jet pump oil?

I’ve gotten everything except fogging oil so far.

This video is pretty good. Make sure you use blue loctite on the pump cone bolts and use thread selaent on the pump cone filler screw
