Armed with the new 300-hp Rotax 1630 ACE engine, the RXT-X 300 has the performance to please from one to three riders.
The RXT-X 300 measures 139.2” (3.54 m) long, 48.2” (1.22 m) wide, weighs 914 lbs. (386 kg) dry, and holds 15.9 gallons (60 L) of fuel.
Wide-angle rear view mirrors flank the Interactive Multifunction Digital Information Center.
Adjustable Ergonomic Steering, which Sea-Doo refers to as A.E.S., allows the rider to customise the X-handlebar width and grip angle. New palm rests for 2016 add more comfort at the grips, as well.
Increased pressure from feet and knees lets the rider grip the Ergolock seat securely, giving the arms better steering control.
Sea-Doo’s Ergolock seating system, developed and perfected on the racing circuit, is found as standard equipment on more models for 2016. The RXT-X 300 is one of them. Combining an adjustable handlebar with inward-angled footwells, and a narrow profile racing seat with hollows the rider can grip with his or her knees, helps reduce the effort to hold on with shoulders, arms and hands in turns. This all means less fatigue for the upper body, as well as faster turns when the rider leans into the turns with more confidence.
With the Intelligent Braking and Reverse system engaged, the RXT-X 300 drops down off plane and stops with the driver in complete control, safely aboard.
Now in its second generation, Sea-Doo’s iBR is an advanced, electronically activated braking and reversing system that the company says can help stop forward motion 160’ sooner than a model with no braking system. It’s activated by a quick squeeze of the left-hand lever, and it also gives the rider better slow speed control, especially useful when manoeuvring around the dock and it always starts in neutral for safety.
An intelligent throttle control, or iTC, provides the RXT-X 300 with three power delivery curves. Its selectable Touring/Sport mode offers throttle response settings that are optimal for two-up cruising, or more aggressive acceleration and mid-range power, respectively. And an Eco mode targets the most economical RPM setting for best economy. Finally, Sea-Doo incorporates Off throttle Assisted Steering, or O.T.A.S., that seamlessly provides additional steering effect when the throttle is released.
To improve lateral stability, the X-Package includes three-position adjustable sponsons to customise turning characteristics from freestyle to aggressive.
To support the high-performance mission and style of this model, Sea-Doo includes what it calls its X-Package, a range of features that start with a race-inspired seat, adjustable ergonomic steering, adjustable rear sponsons, and additional interactive digital gauge functions, including a boost indicator, time/distance to empty, top/average speed/rpm, lap timer and engine temperature.
The new Rotax 1630 produces 300-hp from its 1.6L, aluminium block with increased efficiencies in friction reduction and engine cooling.
The new Rotax 1630 ACE (Advanced Combustion Efficiency) engine is 9% bigger than the venerable Rotax 1503 and creates 15% more power with a boosted 300-hp, according to Sea-Doo. The new engine has a longer stroke compared to the Rotax 1503, raising displacement to 1.6L and increases efficiency in two areas; friction reduction and better cooling. A new protective plasma coating on engine cylinder liners creates a metallic layer that provides a hard and durable surface to withstand piston friction forces, improves surface durability, and produces better heat transfer and superior performance. A re-engineered cooling system includes an additional heat exchanger and larger, more efficient engine oil cooler.
A new, re-designed supercharger with a faster spinning 32-blade wheel (double the blades of the previous version) produces 30% more intake boost and requires no maintenance, according to the builder. A new larger intercooler provides a more dense air charge, aids in increased airflow and features a new air fin design for improved heat transfer. New ignition curves have been developed to efficiently match the increased air boost with the output of the larger fuel injectors, leading to the 15% increase in horsepower, according to Sea-Doo.
High performance is just one of the Sea-Doo RXT-X 300’s missions, and it delivers with gusto. The RXT-X 300 measures 139.2” (3.54 m) long, 48.2” (1.22 m) wide, weighs 914 lbs. (386 kg) dry, and holds 15.9 gallons (60 L) of fuel. At 8020 rpm, we recorded a wide open throttle speed of 60 mph. The most economical cruising speed proved to be 30 mph at 4480 rpm, burning 4.4 gph and achieving a theoretical range of 97 statute miles, with a 10% fuel reserve.
The new RXT-X is designed for large bodies of water and moderate offshore conditions.
An innovative hull Sea-Doo calls the S3 adds to the rider’s confidence and comfort in rough water. It has a deep-V centre section to knife cleanly through chop, and has stepped sections on the wide outer surfaces to help break suction on the hull bottom. It is capable of satisfying performance, but also adds to the comfort of predictable running characteristics for longer rides.
The S3 hull, or Stepped, Stable and Strong Hull as Sea-Doo calls it, has narrow deep-V inner surfaces, and steps to help break suction for better speed.
Sea-Doo’s Interactive Multifunction Digital Information Center, flanked by the speedometer and the tachometer, indicates VTS preset, fuel consumption instant and average, fuel level, hour meter, compass, clock, touring mode, sport mode, ECO mode, F-N-R indicator and more.
A three-gauge cluster on the handlebars — speedo, customisable multifunction digital screen, and tachometer — makes it easy for the driver to evaluate performance and engine conditions, among many other data points, at a glance. There’s an elevated fuel filter, dual drain plugs and a freshwater flush kit to help keep the exhaust and intake system operating reliably throughout the season as the engine features an exclusive closed-loop cooling system. Wide-angle mirrors give a great view behind and to both stern quarters. In addition to the handling and control advantages of the Ergolock seat, Sea-Doo added wet storage under the exclusive removable watertight storage bin, creating over three times more storage capacity than the previous generation — 42.8 gallons (162 L) of total storage and a larger glove box.
