2021 Sea-Doo
RXT-X 300

Its revolutionary lighter platform, combined with the Ergolock System, maximizes control in any condition, making the RXT-X the new benchmark for rough water performance. With the 300-hp engine, 60 mph (96 km/h) is just a few seconds away.

Features may include:

REAR CARGO LINQ SYSTEM

FAST. EASY. SECURE.

Extra rear storage is now possible with the secure Quick-Attach LinQ System. It allows to easily snap a fuel caddy and a bag, or a cooler, to the back of your watercraft using two convenient, integrated attachment points.

LARGE SWIM PLATFORM

CONFIGURABLE. COMFORTABLE. GROUNDBREAKING.

The first watercraft to hang out on the water with the largest swim platform in the industry. Flat, stable and comfortable, it is ideal for boarding, lounging, and prepping for tow sports. Create even more space by removing the rear seat.

STABLE AND PREDICTABLE HULL

AT REST. AT SPEED. ALWAYS STEADY.

Whether you’re at high speeds pounding rough offshore waters, at rest hanging out in a cove or you’re simply boarding from the side, the wider hull offers industry leading stability thanks to a lower center of gravity and improved hull design.

ROTAX 1630 ACE ENGINE

THE MOST POWERFUL ENGINE ON A SEA-DOO, EVER

Supercharged with an external intercooler, the advanced combustion efficiency (ACE) technology delivers high efficiency and amazing acceleration. This is the most powerful engine on a Sea-Doo producing a thrilling 300-hp.

INGENIOUS STORAGE

DIRECT ACCESS FRONT STORAGE

All your gear is now within arm’s reach. The industry’s first direct-access front storage opens by simply raising the handlebar assembly. No standing required. It’s the smartest water-resistant storage we’ve ever built into a watercraft, offering room for your next adventure.

LOCK IN YOUR SEAT

ERGOLOCK SYSTEM WITH MODULAR SEAT

The narrow racing seat places your knees closer together to hold on tighter while improving the transition into standup riding. Plus, the removable rear seat gives you even more space for hanging out on the rear platform, sunbathing or a face-to-face picnic.

CLOSED-LOOP COOLING SYSTEM

A SEA-DOO EXCLUSIVE

This technology prevents corrosive saltwater and damaging debris from entering the engine, for increased reliability and peace of mind.

TAKE PERFORMANCE FURTHER

ADD ON THE PERFORMANCE PACKAGE

With X-Sponsons for cornering stability and our innovative ErgoLock System featuring a narrow racing seat, specially angled footwell wedges and adjustable X-steering, you and the machine become one.

PRECISION TUNING

VARIABLE TRIM SYSTEM WITH LAUNCH CONTROL

Quickly access the Variable Trim System (VTS) on the handlebar for fine-tuned handling based on rider preference, water conditions, and number of passengers. Plus a handlebar-activated launch control to provide perfectly controlled acceleration.

KEEP IT DRY AND CHARGED

WATERTIGHT PHONE COMPARTMENT

A watertight compartment with integrated USB port* allowing your devices, including phones or action cameras, to stay charged and ready to go—snug in an impact-absorbing, watertight cradle.
