Twenty years ago, GreenHulk began with one apple-green Sea-Doo RXP 215, a desire to make it faster and two young boys who gave the project ski its enduring name.
Today, GreenHulk encompasses one of the PWC industry’s best-known enthusiast forums, an international performance and replacement-parts business, a substantial library of technical information and videos, and—soon—a 7,500-square-foot workshop offering everything from routine maintenance to complete race ski builds.
GreenHulk PWC Performance is marking that two-decade progression with a limited anniversary sale on several of its products. At the same time, recent construction updates from Louisiana show that the company has no intention of treating its 20th anniversary solely as an occasion to look backward.
The GreenHulk story began after founder Jerry Gaddis purchased a 2004 Sea-Doo RXP. The newly introduced 215-horsepower watercraft was already among the most powerful production machines of its day, but Gaddis wanted more.
His two sons began calling the bright green RXP the “Green Hulk,” and the name followed the project as Gaddis documented its development, testing, setbacks and performance gains online.

What began as a personal build blog attracted a growing audience of riders asking questions and exchanging information. As the volume of individual emails became unmanageable, Gaddis developed GreenHulk.net into a public forum where those conversations could take place collectively.
Home tuners, racers, ski builders and professional performance shops gathered there to share testing results, technical knowledge and hard-earned lessons. GreenHulk.net developed into one of the PWC industry’s most prominent performance forums and helped preserve a deep, searchable record of the sport’s development.
As forum members increasingly asked where they could find specialized parts, Gaddis recognized another need. The enterprise expanded into an online store connecting customers with factory replacement components and aftermarket performance products.
GreenHulk’s connection with The Watercraft Journal also reaches back to WCJ’s earliest days. In a November 2013 column—among the first pieces published by the then-new outlet—WCJ founder Kevin Shaw credited Gaddis with helping him get the publication to where it is today.
One month later, WCJ published an extensive profile tracing Gaddis’ path from modifying that first RXP to operating the industry’s rapidly growing performance forum and online store. More than a decade after those articles, GreenHulk is taking another substantial step.
In February 2025, GreenHulk announced plans to build a 7,500-square-foot workshop in the Morgan City/Amelia area of Louisiana. The facility, officially named GreenHulk Garage, was planned as a physical counterpart to the company’s worldwide online operation.
Greg Gaddis told WCJ at the time that demand for hands-on work had grown beyond what he could efficiently accommodate in his two-car garage.
His goal for the new facility was to provide turn-key performance packages ranging from basic bolt-on upgrades to complete race builds, along with maintenance, repairs and engine work.
The company also said the shop would offer performance tuning for ATVs and outboard motors while allowing GreenHulk to serve local customers in person.
Its online store and technical support operation would continue serving customers worldwide.Construction has taken that plan steadily from announcement to reality.
An Aug. 13 update showed the building’s steel framework rising from the completed foundation. By Aug. 31, exterior sections were in place and roofing work was underway.
GreenHulk’s latest shared update, posted Sept. 12, showed a substantially enclosed structure, although persistent rain had left the site muddy and slowed the work.
“Rain, rain, go away… we’ve got a building to finish and skis to build!” the company wrote.
While the new garage represents GreenHulk’s next chapter, its anniversary sale returns attention to the products and customers that helped make the expansion possible.
The limited-time promotion includes the GreenHulk Sea-Doo Rear Deck Vent, reduced from $99.95 to $45.95, and carbon-fiber air intakes for Yamaha and Sea-Doo models, each reduced from $279.95 to $223.96.
Two assembled jet-pump packages are also included. The Sea-Doo Spark Complete Jet Pump and the complete jet pump for 2004-and-newer Sea-Doo models are each reduced from $900 to $720. The GreenHulk Performance Tee in Grey Concrete is marked down from $19.95 to $15.96.
The products cover a range of needs, from increasing airflow and engine-bay ventilation to replacing a damaged or worn pump—or simply displaying a little GreenHulk allegiance at the lake.
For longtime PWC enthusiasts, however, the anniversary marks more than a collection of discounted parts. GreenHulk’s evolution parallels much of the modern performance industry’s own development: riders experimenting in home garages, sharing what they learned online, connecting enthusiasts with increasingly specialized components and gradually building a worldwide technical community.
Now, 20 years after one green RXP supplied the name, GreenHulk is building a garage large enough for what that community became. Additional information about the anniversary promotion and available products can be found at GreenHulk PWC Performance.
