For riders pushing the limits of their Sea-Doo, the RIVA Racing iDF Delete Kit is a tried-and-true upgrade available through GreenHulk PWC Performance Store – now at a discounted price. The kit replaces the iDF system—a clever design meant for low-speed maneuvering that can, at high RPMs, create unwanted drag and stress on internal components—with OEM engine and driveline parts that backdate your setup to non-iDF specification.
The iDF system has built-in safeguards to prevent engagement while riding, but even so, modified craft operating above 8,400–8,500 RPM can see premature failures in the gearbox and associated driveline components. Removing the iDF reduces mechanical drag, improves reliability, and opens the door for performance modifications beyond RIVA Stage 2. Riders will notice smoother top-end response and less stress on small moving parts.
GreenHulk carries kits for multiple models, including:
-
2025 GTX Limited 325 – $1,488.32 retail, $1,413.90 discounted
-
2022–25 RXT/GTX 300 – $1,550.78 retail, $1,473.24 discounted
-
2021 GTX 300 – requires a different output sleeve and driveshaft, both in stock at GreenHulk
Installation isn’t for the casual weekend wrench-turner. RIVA and GreenHulk recommend certified Sea-Doo mechanics or highly experienced technicians. It requires deactivating iDF through the BRP Dealer Diagnostic System (BUDS) or Maptuner X with a tuning license, along with several specialty tools and careful inspection of the carbon seal and floating ring.
For those serious about Sea-Doo performance, the iDF Delete Kit delivers smoother rides, reduced driveline drag, and improved reliability, making it a staple upgrade for modified craft. GreenHulk remains the go-to source for riders looking to push their machines beyond stock limits.
