SeaDoo HX Rear Sponsons

(2 customer reviews)


Rear sponsons for the Seadoo HX provide better stability and rear grip compared to the stock rear sponsons. The deeper flange and relief cuts grab more water in the turns as well as provide pressure reliefs for controlled turning. We require installing these sponsons using our proven silicone adhesive.

These SeaDoo HX rear sponsons give you maximum stability and corner grip where you need it most. The integrated wedge design allows water to flow past the bond flange for an increase in speed and water flow. To help reduce rear lifting in the corners caused by the solid sponsons, we added relief areas for improved grip through less water pressure.

Nick, a local LHC rider, tested out our sponsons and said, “First ride with the new sponsons, it’s incredible. Grips so well, tracks perfect in the water, doesn’t want to shift. This thing is on rails.” Rider Testimonial Video

    These sponsons helped me finish 2nd place at the Marietta, Ohio round of the HydroCross Series at the Powerboat Nationals!! I had custom sponsons on my HX up until 2 weeks ago and switched to the Pro Watercraft HX rear sponsons and I am extremely impressed with the hook up and enhanced handling of the new sponsons. Very happy with my purchase!
