This Wedge rear sponson is specifically designed for the 2021+ Yamaha SuperJet equipped with the four stroke engine. The sponson design gives you more stability, more grip, faster acceleration, and increased top speed. We highly suggest these Wedge rear sponsons as we have seen a massive 3+ mph gain in top speed. Our unique blade design is the best shape to maximize grip and stability. Install this sponson with the ProWatercraft Fattie front sponsons to get maximum control and comfort while riding. For racing or competition use, you may be allowed to only use one set of sponsons to be legal. Check with your racing organization for details.
To maximize your turning grip and speed we highly suggest our ride plate and RB300 intake grate.
