How to Winterize a Seadoo

Winterize your Seadoo to prepare it for storage.

Winterizing is a catchall term for preparing a Seadoo or any other personal watercraft for winter storage. The winterizing process is the best way to ensure that your Seadoo remains in good condition during long periods of disuse. Furthermore, winterizing ensures that your Seadoo will be ready to use -- without hassle or repair -- when it's time to drop the craft in the water again.
