Sea-Doo RXP-X 300 PWC For Sale

The Sea-Doo RXP-X 300 is the performance flagship of the Sea-Doo personal watercraft lineup, a two-rider-capable muscle craft built around outright speed and aggressive cornering rather than leisurely cruising. It rides on the T3R hull, measures 130.6 inches in overall length, 49.2 inches across the beam, and 44 inches tall, making it slightly shorter than runabout-style models like the RXT-X and GTX. This is a machine aimed at experienced riders; its quick reflexes and high G-loads in corners reward people who can lock in and hold on, and it is generally best treated as a single-rider craft despite the available two-up seat.

Power comes from the supercharged, intercooled Rotax 1630 ACE engine, a 1630cc unit rated at 300 horsepower (the 2026 model is rated at 325 horsepower). It requires 91-octane premium fuel and uses closed-loop cooling with a radiator and coolant rather than drawing lake or sea water through the engine. Launch control is standard, and Sea-Doo measured 0-50 mph in 2.9 seconds and 0-60 mph in 3.6 seconds. U.S. units are restricted to a Coast Guard-approved 68.5 mph top speed, while an unrestricted test unit reached a GPS-confirmed 73.8 mph at 8,000 rpm. Three drive modes — sport, normal, and eco — change acceleration and, in eco, dial back top speed to save fuel, drawing on the 18.5-gallon fuel tank. Owners report the RXP-X 300 burns through fuel faster than the RXT-X 260 when ridden hard.

Handling is the reason to choose this model. The deep-keeled T3R hull carves tightly and stays planted, with engineers adding serrations along the inner chine that aerate the water for more forgiving, gradual turns at slower speeds while preserving the bite at full throttle. For the 2021 redesign, Sea-Doo cut 67 pounds and moved the engine and fuel tank two inches forward, shifting the pivot point beneath the rider and allowing the craft to carry full speed through a corner without backing off the throttle. A top-loader intake grate and a polished, re-pitched impeller improve initial hookup, and X sponsons help grip in turns. A 2026 unit weighs 798 pounds dry with the sound system fitted.

The helm centers on an adjustable hydraulic steering damper that lets you firm up or lighten the handlebars to reduce arm fatigue at speed. A 10.25-inch touchscreen is offered (it is the one model where the screen is optional rather than standard), and it pairs with the BRP Go app through a corded iPhone connection to show Navionics charts, with the full marine chart subscription costing roughly $20 per year. The display supports live distance-to-empty and time-to-empty readouts, customizable gauges, and a group-ride function that tracks up to 20 connected units, provided each rider has cellular service. Because the touchscreen locks out above 8 mph, handlebar controls duplicate every function for use at speed.

The cockpit uses the Ergolock R racing seat with a thick, adjustable backrest offering up to five inches of adjustment, plus double-angled footwell wedges and padded knee coves that let the rider lock in and steer at full throttle without relying solely on arm strength. Despite the performance focus, storage is generous: 40.6 gallons total, split between a 30.7-gallon front bin and a 2.5-gallon glove box, since the deck and hood are shared with the GTI. The LinQ accessory system at the stern accepts coolers, fuel caddies, and dry storage. There is no rear reboarding step, a deliberate weight-saving choice, and the handlebars are fixed unless the telescoping neck option is added.

For buyers shopping the RXP-X 300 for sale, pricing has varied by year and trim: the 2021 carried a base MSRP of $15,799 in Millennium Yellow, with a $300 upcharge for the Midnight Purple and Manta Yellow scheme. The 2023 Apex 300, a one-year limited edition with a real carbon-fiber hood and racing seat, listed around $21,000 in the U.S. and $26,000 in Canada. Things to weigh include the premium-fuel requirement, fuel consumption in sport mode, the lack of a reboarding step, and that extras like the 100-watt Bluetooth sound system, two-up seat, and telescoping steering are option-box items on the base configuration.
