New and improved – while the advertising slogan may be trite, the words take on some serious impact when the one throwing them out there is GreenHulk PWC Performance.
Almost before the New Years fireworks had faded, GreenHulk was rolling out news to keep PWC fans warm at heart, even if their fingers are frozen by January’s uncooperative cold weather.
GreenHulk has announced two new products already, both for 2025 model skis – one for Sea-Doo’s 2025 GTX Limited 325 and one for the 2025 Yamaha JetBlaster.
For the JetBlaster, the Pro-Series Sponsons will dramatically improve handling, with superior fin & backing plate design and a bulletproof mounting system that features billet aluminum backing plates and four anchor points with aluminum inserts in sponson fins. The mounting plate angle and sponson fin depth are adjustable to control the amount of influence they have on the craft, and they are IJSBA-legal for all classes.
Easy installation uses original mounting studs and purchase includes all necessary hardware and installation instructions. Priced at $489.95, but use code “greenhulk at checkout for a $49 discount.
For Sea-Doo, RIVA’s new Sea-Doo 2025 GTX Limited 325 iDF Delete Kit is now available from GreenHulk, on sale for $1,400.84, down from a regular pricing of $1,474.57
As noted by The Watercraft Journal in late 2023 when RIVA released the iDF Delete Kits for 2022-23 RXT-X and 2022-24 GTX models with iDF, Sea-Doo’s Intelligent Debris Free system (iDF) is a set of gears in the engine that can reverse the rotation of the impeller, reversing the water flow so debris is blown out, eliminating the need to manually removing debris from the intake.
As handy as that feature is for recreational users, the system has become known for early failure on high-performance watercraft operated at 8,400 rpm and above, and has a tendency to negatively impact performance and limit modifications.
Meant primarily for race skiers and those who wish to tune their skis for speeds in the upper 80s – and above – this kit directly replaces your ski’s iDF system.
In an earlier interview, RIVA’s Mike Hodges told The Watercraft Journal, “Since BRP updated the iDF internals, we’ve found that the failure rate is pretty much a non-issue on stock craft as well as craft modified up to Stage 2. However, we’ve received reports of a few iDF failures on modified craft run above 8,400rpm, which is well beyond the system’s intended use.”
RIVA’s iDF-removal kit uses all OEM engine & driveline components, and instructions directly out of the Sea-Doo shop manual, to eliminate the iDF system and return the ski to one-way only driveshaft rotational operation for improved reliability.
“In addition to improved reliability we found that overall performance is improved by what we believe is a reduction in mechanical drag related to the iDF gearbox components,” Hodges said.
While the process does require “deactivating” the iDF function through BRP Dealer Diagnostic System (BUDS) or Maptuner X with Tuning License, and requires a high-level mechanical proficiency and specialized tools to complete, use of this kit will enable performance modifications beyond RIVA Stage 2, as well as that reduction of mechanical drag on the driveline caused by iDF gearbox components, resulting in increased performance.
Specialized tools required include: PTO Sleeve Remover/Installer ($86.99), Water Pump Impeller Tool ($28.09), Crankshaft Locking Tool ($57.99), Driveshaft C-clip Remover ($154.89), Water Pump Shaft Tool ($30.89) and Oetiker Pliers ($47.00)
While not “new” (and technically announced before the new year, with the release posted on Dec. 30), GreenHulk’s popular and well-proven Victory Turbo Kit for Sea-Doo Spark/Trixx – is now in it’s third revision – with even better durability and smoother installation combined with black powder coated parts for outstanding look.
See the full data from the original post below:
This is a complete engine hardware kit and includes all parts you need to convert your Sea-doo Spark/Trixx and turn it into a turbocharged performance machine! We highly-recommend you replace the impeller with a Solas 13/18 (not included in this kit). You will also need to flash your ECU with a new tuning software especially designed for Sea-doo Spark/Trixx with this turbo kit. The flash (programming) is fast and effortless with our tuning software and the MaptunerX which also brings more useful features for the Sea-Doo Spark.
