If you want the ultimate Yamaha JetBlaster setup, the Stage 4 Performance Kit brings together every key upgrade to deliver the most complete and capable ride possible.
By combining improvements to pump performance, engine breathing, and handling control, Stage 4 transforms the JetBlaster into a far more aggressive and performance focused machine. Acceleration becomes stronger, cornering sharper, and the ski feels far more planted and predictable when riding at speed.
Whether you’re chasing maximum performance, riding aggressively in challenging water conditions, or simply want the best possible JetBlaster setup, Stage 4 unlocks the full potential of your ski.
Our Stage 4 Kit for the 2025+ Yamaha JetBlaster represents the most advanced upgrade package in the Worx JetBlaster performance range.
By combining all previous performance improvements with additional high performance components, Stage 4 delivers the strongest acceleration, sharpest handling, and most responsive ride available for the JetBlaster platform.
You’ll notice faster launches, greater stability at speed, and a ski that feels incredibly planted and confident even when ridden aggressively. Stage 4 takes everything that makes the JetBlaster fun and amplifies it, creating a machine that performs at the highest level on the water.
