Our local Sea Doo dealer will service the Rotax motors but they are careful to say they never had been a Sea Doo boat dealer. They won't turn work away if its something they can fix, really its a 21/23 foot jet ski. I don't understand why a Sea Doo PWC dealer wouldn't want the business, if its all the same parts and they can easily get them why not?? I know my dealer says depending on the year of boat their BUDS system may not work with the boat.
