Sea-Doo has officially released the 2027 RXP-X 350, a high-performance personal watercraft that sets a new record for acceleration in the PWC industry. This latest model represents a significant engineering achievement, combining increased power output with refined propulsion systems to deliver performance that previous generations couldn’t match.

The Numbers: What Makes This PWC the Fastest

The new RXP-X 350 accomplishes what many in the industry thought impossible: it achieves a 0-to-60 mph time of just 3.1 seconds, nearly three-tenths of a second faster than the outgoing RXP-X 325. To put this in perspective, the previous model already dominated the market with a 3.4-second acceleration time. This improvement matters significantly for riders who prioritize thrilling on-water performance.

While U.S. manufacturers and the Coast Guard maintain an informal agreement capping PWCs at 70 mph top speed, the real competition happens in how quickly you reach that limit. Sea-Doo has essentially rewritten the playbook in this regard.

Engine Modifications That Drive Performance

The RXP-X 350 uses the same three-cylinder, 1,630 cc supercharged Rotax engine foundation as its predecessor, but Sea-Doo made substantial revisions throughout. The manufacturer increased power output by 7.7 percent, adding 25 horsepower to the overall package. This engineering feat required several critical upgrades beyond simply bolting on new parts.

One major modification involves the supercharger booster wheel. Sea-Doo increased its capacity to enhance air volume and boost pressure, allowing the engine to produce more power without requiring a complete redesign. Additionally, the team raised the engine’s rev limit from 8,250 rpm to 8,500 rpm, extracting additional performance from the existing displacement.

Since increased power creates additional stress on internal components, Sea-Doo strengthened critical areas including the jet-pump system, conrods, and bolt designs. Engineers optimized these elements to handle the extra horsepower reliably. Similar to how manufacturers enhance other powersports vehicles with technology upgrades, Sea-Doo took a comprehensive approach rather than simply increasing displacement.

Chassis and Hull Refinements

You cannot maximize additional engine power without upgrading the platform that delivers that power to the water. The RXP-X 350 retains the proven T3-R hull design from the previous generation, but Sea-Doo engineers made important modifications to the ride plate. These changes optimize how the watercraft transfers the extra horsepower into acceleration, helping achieve that impressive 3.1-second sprint time.

This balanced approach to performance demonstrates the maturity of Sea-Doo’s engineering team. Rather than chasing raw numbers, the company ensured that every upgrade works together as a cohesive system.

The 2027 RXP-X 350 carries a starting MSRP of $23,699 in the United States. This represents a $3,500 increase over the previous RXP-X 325, a meaningful jump that reflects the performance improvements and enhanced engineering. For buyers prioritizing maximum acceleration and on-water thrills, this price point positions the RXP-X 350 as a premium offering in the high-performance PWC category.

What This Means for Shoppers

If you own an older PWC, the arrival of the RXP-X 350 demonstrates how rapidly powersports technology evolves. Even compared to the RXP-X 325 from just a couple of years ago, the acceleration improvement is substantial. For riders who prioritize performance and consider personal watercraft a recreational priority, the RXP-X 350 represents the current pinnacle of what manufacturers can deliver within existing regulatory constraints.

Performance enthusiasts should recognize that Sea-Doo achieves these results through careful engineering rather than brute force. The modifications to the supercharger, rev limit, and supporting systems show a company pushing the boundaries of what’s possible within the current PWC framework. As manufacturers across the powersports industry continue innovating, buyers benefit from each company’s pursuit of performance excellence.

For those shopping the PWC market today, the timing of the RXP-X 350 launch means you should seriously consider whether the acceleration improvements justify the additional investment. If maximum performance on the water represents your priority, Sea-Doo’s latest offering delivers measurable advancement over previous generations and competitors alike.
