I believe the standard warranty is 1 year on the seadoo. I would look in your service manual or call you local dealer and ask if it might have an extended warranty based on the Hull # on the seadoo. That would be you best bet.

The standard warranty varies by the type you buy when you get your ski. Like a car, when you buy it, you are offered different plans for the type protection you need.
Like Karl said, may be best to ask your local dealer for the advice.
