BRP Inc. is betting big on speed for 2026. The Canadian powersports manufacturer has positioned its latest Sea-Doo RXP-X 325 as the fastest production personal watercraft ever sold, claiming a top speed of 70 mph and a 0-to-60-mph time under 3.4 seconds. Those figures, published in BRP’s official press materials and product page for the RXP-X 325, place the craft ahead of its closest rivals from Kawasaki and Yamaha on paper. But what does “certified” actually mean here, and how does the new flagship stack up in practice?
What powers the RXP-X 325
At the center of BRP’s speed claims is the Rotax 1630 ACE engine, a supercharged 1,630cc inline three-cylinder that the company rates at 325 horsepower. That figure represents the highest factory output BRP has ever offered in a personal watercraft and a meaningful jump from the 300 hp Rotax engine found in the previous-generation RXP-X 300, which had been the brand’s performance benchmark since its introduction.
BRP’s investor relations press releases for the 2026 model year describe the engine as part of a broader platform rollout across its performance lineup. The company uses phrases like “highest horsepower” and “fastest accelerating” to frame the RXP-X 325, and a separate release highlights new digital display and connectivity features added to the model for 2026.
The RXP-X hull itself has a long competitive pedigree. Designed for closed-course buoy racing, it uses a deep-V design with an aggressive chine that prioritizes cornering grip and high-speed stability over the softer ride characteristics found in touring or recreation models. Combined with the additional 25 horsepower, BRP’s sub-3.4-second acceleration claim is plausible given the platform’s track record.
How it compares to the competition
The personal watercraft performance segment is a three-brand race. Kawasaki’s Ultra 310 series, powered by a supercharged 1,498cc inline four-cylinder rated at 310 hp, has long been the horsepower leader among Japanese manufacturers. Yamaha’s GP1800R SVHO uses a supercharged 1,812cc engine rated at approximately 250 hp at the impeller, though Yamaha historically measures output differently than BRP and Kawasaki, making direct comparisons tricky.
On claimed top speed, the RXP-X 325’s 70 mph would edge out the Kawasaki Ultra 310 variants, which independent GPS tests by media outlets have typically recorded in the mid-to-high 60s depending on conditions, rider weight, and fuel load. Yamaha’s GP1800R SVHO generally lands in a similar range. If BRP’s number holds up under independent testing, the RXP-X 325 would represent a genuine, if incremental, step forward for the segment.
Pricing for the 2026 RXP-X 325 has not been widely published as of June 2026, and dealer allocation details remain limited. Previous RXP-X models have carried MSRPs in the $17,000 to $19,000 range before dealer markup, accessories, and trailer costs. Buyers should expect the 325 to sit at or above the top of that window given the powertrain and technology upgrades.
What “certified” actually means
The word “certified” carries specific legal weight in the marine industry, and it does not mean what most buyers probably assume. Federal regulation 40 CFR 1045.660, maintained by Cornell University’s Legal Information Institute, governs how personal watercraft engines are certified for sale in the United States. That certification process addresses EPA exhaust emissions compliance, not speed records or performance benchmarks.
When a PWC engine is “certified” under this framework, it means the powerplant meets federal environmental standards. It does not mean an independent body strapped a GPS unit to the hull and recorded a verified 70 mph under controlled conditions.
No recognized speed-record organization, including Guinness World Records, appears in BRP’s press materials or available reporting as having validated the RXP-X 325’s top speed. The personal watercraft industry does not have a single universally recognized body that certifies speed claims the way, for example, the FIA certifies land-speed records for automobiles. That absence is not unique to BRP; it applies equally to Kawasaki and Yamaha performance claims.
This does not make BRP’s numbers suspect. As a publicly traded company on the Toronto Stock Exchange, BRP faces regulatory scrutiny over statements made in investor communications, which creates a financial incentive for accuracy. But there is a meaningful difference between a manufacturer’s internal test results and data published by an independent organization with a transparent testing protocol. Buyers should treat the 70 mph figure as BRP’s own finding until independent media or a third-party testing body publishes corroborating GPS data.
Questions worth asking at the dealership
Shoppers considering the RXP-X 325 can cut through the marketing by asking a few pointed questions:
- Under what water and weather conditions did BRP record the 0-to-60 and top-speed figures?
- Was the speed measured by GPS or by the craft’s in-dash speedometer, which can read optimistically?
- Does the 70 mph claim assume a single lightweight rider with minimal fuel, or a more typical real-world load?
- Is the figure an average of multiple passes in opposite directions (the standard protocol for eliminating current and wind bias), or a single best run?
Dealers may not have engineering-level answers to all of these, but the questions signal informed buying. BRP’s downloadable spec sheet, linked from the official model page, may include testing notes and fuel-load assumptions that add useful detail beyond the headline numbers.
For prospective racers, it is also worth noting that sanctioning bodies for closed-course and endurance racing impose their own class rules, technical inspections, and modification restrictions. A craft marketed as the “fastest” may still require setup changes like impeller swaps, ride plate adjustments, or ECU tuning before it is competitive in a specific racing class.
Where the RXP-X 325 fits in the bigger picture
Strip away the certification semantics and the RXP-X 325 represents a straightforward evolution of BRP’s performance strategy: more power from a proven engine platform, incremental hull and technology refinements, and aggressive marketing language designed to claim segment leadership. That playbook is identical to what Kawasaki and Yamaha run with their own flagships.
The 70 mph claim is plausible. The 325 hp rating is the highest in the production PWC market. And the RXP-X hull has decades of racing development behind it. What is missing, for now, is the independent verification that would move the “world’s fastest” label from marketing assertion to documented fact.
For buyers who want the quickest production watercraft available in 2026, the RXP-X 325 is the most credible candidate on spec alone. For those who want proof before paying a premium, the smart move is to wait for independent GPS-verified tests from established watersports media outlets, which typically publish detailed performance data within weeks of a new model reaching dealers. Until that data arrives, BRP’s numbers tell a compelling story. Whether it is a verified one remains an open question.
