No this will not work on a Sea Doo Spark because that jet ski does not have enough power to lift a 150 lbs. rider above 10 feet. Flyboard by Zapata has an adapter but even their Flyboard will not go above 10 fit. It’s just not fun. For this reason we do not make an adapter to fit any jet ski that’s below 130 HP. Don’t believe anyone who makes a claim that their board can be hooked up to a jetski with less than 130 HP. Even though it can be done you will not enjoy flying. And you will be over stressing your jet ski which eventually will lead to major engine issues.
