One of the most common complaints we hear from riders stepping into today’s high-horsepower Sea-Doo platforms is this: the power is there, but the hookup isn’t always. Hard launches turn into brief cavitation, aggressive throttle inputs don’t always translate cleanly to forward motion, and the ski can feel like it’s fighting to put all that output into the water.
That problem isn’t unique — and it isn’t new. As factory power levels climb, the jet pump becomes one of the most important links in the chain. If it can’t move enough clean water efficiently, performance gains elsewhere start getting wasted.
That’s where solutions like the RIVA / SOLAS Sea-Doo 161mm 14-Vane Pump, available through GreenHulk PWC Performance Store, come into the conversation.
Why the Stock Pump Can Become the Bottleneck
On modern GTX, RXP-X, and RXT-X models — especially 300 and 325-horsepower platforms — the pump is asked to do a lot. Under heavy load or aggressive launches, cavitation can creep in, reducing acceleration and making the ski feel inconsistent off the line.
The issue usually isn’t a lack of power. It’s water flow control.
More controlled flow means better hookup, stronger launches, and more usable acceleration — which is exactly what higher-vane pump designs aim to address.
The GreenHulk Solution: RIVA / SOLAS 161mm 14-Vane Pump
GreenHulk’s offering of the RIVA / SOLAS 161mm 14-vane pump is designed to move more water, more efficiently, while keeping flow clean under load.
The pump uses a 14-vane stainless steel stator and matching 14-vane nozzle, increasing water control through the pump assembly and significantly reducing cavitation compared to lower-vane designs. The result is stronger hookup at launch and more consistent power delivery through the throttle.
A standout feature is the inclusion of three interchangeable stainless nozzle rings (82mm, 83mm, and 84mm ID). This allows riders to fine-tune performance while also extending service life — rather than replacing the entire housing as wear occurs.
What Riders Notice on the Water
Based on rider feedback and real-world use, this type of pump upgrade isn’t about noise or visual flash. It’s about how the ski behaves when you ride it.
Riders commonly report:
-
Quicker, harder launches
-
Reduced cavitation under heavy throttle
-
More consistent acceleration
-
Improved top-end efficiency
-
Better hookup on high-horsepower setups
As one GreenHulk customer put it in the comments, the gains are “monstrous.”
Built for Today’s High-Power Sea-Doos
The RIVA / SOLAS 161mm 14-vane pump is compatible with a wide range of modern Sea-Doo models, including GTX, RXP-X, RXT-X, and GTX Limited platforms from 2016 through current 300- and 325-horsepower models.
It’s built as a durability-minded upgrade, featuring:
-
SOLAS 161mm pump housing
-
14-vane stainless stator section
-
Matching 14-vane nozzle
-
Stainless steel wear ring
-
Interchangeable nozzle rings for tuning and longevity
Installation does require new OEM jet pump seals, which should be planned for as part of the upgrade.
The Takeaway
If you’re riding a high-output Sea-Doo and feel like the ski isn’t always translating power into motion — especially off the line — the pump is one of the first places worth looking.
Upgrades like the RIVA / SOLAS 161mm 14-vane pump from GreenHulk focus on improving how power gets to the water, not just how much power the engine makes. For riders chasing cleaner launches, stronger hookup, and more usable performance, it’s a solution that addresses a very real problem.
