Sea-Doo RXP-X 325 PWC For Sale

The Sea-Doo RXP-X 325 is the performance flagship of the Sea-Doo lineup, a single-rider sit-down personal watercraft built on the T3R hull for aggressive cornering and outright speed. Power comes from the supercharged Rotax 1630 ACE, a 1630cc three-cylinder engine producing 325 horsepower and running closed-loop cooling with a radiator and coolant rather than drawing in lake or sea water. It requires 91-octane premium fuel. This is a machine aimed at experienced, performance-focused riders who want one of the fastest production skis available off the showroom floor.

The 325 engine is a substantial redesign rather than a retune. The cylinder block was recast with thicker bosses and added webbing, the connecting rods got stronger hardware, and the pistons were redesigned with tilted ring grooves, deeper valve pockets and a DLC coating. The forced-induction unit Sea-Doo calls a compressor uses a mechanical jaw clutch and planetary gear to spin a smaller impeller to roughly 100,000 RPM, about a quarter faster than the previous 300 engine, while keeping the intake charge close to 40% cooler. A new blowoff valve regulates boost, and a Bosch engine control module, the same family used in the turbocharged Maverick side-by-sides, runs the system with an O2 sensor for live air-fuel data. Redline sits at 8,250 RPM, 250 above the prior engine.

On the water the RXP-X 325 hits 0 to 60 mph in about 3.4 seconds, two-tenths quicker than the previous 300, with launch control to manage the takeoff against the polished stainless impeller. The factory speed limiter holds top speed near 70 mph, with a quarter-mile run recorded at 15 seconds flat trailing off around 68 to 69 mph because the ski tops out before the end of the run. Full top speed once the running-in phase is complete measures about 73 mph (117 km/h), compared with roughly 60 mph (97 km/h) while the ski is still breaking in. The mid-range pull is the standout, snapping from a 40-mph cruise to 70 with no surging or heat soak through repeated hard corners.

The cockpit centers on the ErgoLock R racing seat, which locks a single rider in place and is adjustable fore and aft, paired with double-angled footwell wedges and grip mats to brace your feet under hard acceleration and cornering. A carbon fiber hood with Sea-Doo's X badge tops the bow, and a hydraulic steering damper offers three settings from light to heavy resistance, useful because the high-performance X sponsons can turn the craft sharper than many riders expect. For 2024 the ski carried a 7.6-inch color display; 2026 models add an optional 10.25-inch touchscreen with the BRP Go app, Navionics charting, a group-ride function for up to 20 units, and Sport, Normal and Eco drive modes, with handlebar toggle switches for control above idle speed.

Despite being a midsize craft, the RXP-X 325 carries usable storage, with roughly 40.6 gallons of cargo room and a deep glove box that includes a separate waterproof compartment with a USB charge port. The fuel tank holds up to 18.2 gallons, and the bow storage exceeds that of full-size skis and the Yamaha GP SVHO. It measures 130.6 inches long, 49.2 inches in beam and 44 inches tall, with a dry weight listed around 778 pounds before oil, coolant and battery. Color options include Ice Metal with Manta Green and the 2026 Gulfstream Blue Premium.

For buyers, the trade-offs are deliberate. The handlebars are set low without tilt adjustment, so the RXP-X is not suited to standing while riding, and the bow storage requires standing to access since the handlebar assembly does not lift. A two-seat configuration, rear boarding step and premium audio speakers are extra-cost options on this model in the US. Anyone shopping the RXP-X 325 for sale should weigh its stripped-down, race-focused intent against added-weight accessory packages, since the ski is engineered to be light, locked in and built for serious performance.
