Electronic Fuel Injection and Intelligent Throttle Control help riders manage the engine's performance across changing riding conditions.

For experienced enthusiasts seeking a powerful sport watercraft, the GTR-X 300 offers an exciting alternative to traditional touring-oriented models.

Intelligent Brake & Reverse (iBR)

The Intelligent Brake & Reverse system provides electronic braking and reverse thrust control directly from the handlebars.

This technology helps simplify maneuvering around docks, marinas, boat ramps, and other watercraft.

The system also provides neutral control, making low-speed operation more convenient.

Even on a high-performance watercraft, iBR adds valuable practicality for everyday recreational use.

Lightweight Performance Hull

The GTI-based hull combines lightweight construction with responsive recreational handling.

Its Polytec Gen II material helps reduce overall weight while maintaining durability for regular recreational use.

The hull provides an agile riding feel that complements the GTR-X 300's powerful supercharged engine.

For riders who enjoy acceleration, quick directional changes, and sporty handling, this platform offers an engaging experience.

Performance-Oriented Ergolock Seating

The Ergolock performance seat is designed to help riders maintain a secure position during acceleration and aggressive cornering.

Its ergonomic shape provides support while allowing riders to shift their body position as riding conditions change.

This seating design is particularly useful when taking advantage of the GTR-X 300's substantial horsepower.

The performance-oriented layout also contributes to the watercraft's sporty appearance.

Adjustable Handlebar Riser

The adjustable handlebar riser allows riders to customize their steering position.

This flexibility helps accommodate different rider heights and preferred riding postures.

A properly adjusted handlebar position can improve comfort and control during extended recreational outings.

For sport-oriented riding, the adjustable riser helps riders find a confident, natural steering position.

Variable Trim System

The Variable Trim System allows riders to adjust the watercraft's running attitude according to conditions and riding preferences.

Trim adjustments can help optimize acceleration, handling response, and cruising characteristics.

The extended trim capability provides additional flexibility for riders who enjoy experimenting with different performance settings.

This system allows the GTR-X 300 to adapt to a variety of recreational riding situations.

Launch Control for Strong Acceleration

The Launch Control system helps manage acceleration during performance-oriented starts.

This feature allows riders to take advantage of the engine's substantial power in a more controlled manner.

For experienced riders who enjoy powerful acceleration, Launch Control adds another dimension to the GTR-X 300's performance capabilities.

ECO and Sport Riding Modes

The ECO and Sport riding modes allow riders to adjust throttle response according to their preferences.

ECO mode provides smoother acceleration and supports more economical recreational operation.

Sport mode delivers a more immediate throttle response for riders who want energetic acceleration.

These selectable modes make the GTR-X 300 adaptable to different riding styles and conditions.

The rear boarding platform and integrated boarding ladder make recreational stops and swimming activities more convenient.

All occupants and equipment must remain within the manufacturer's maximum weight capacity.

Closed-Loop Cooling System

The Closed-Loop Cooling System helps regulate engine temperature using coolant rather than circulating surrounding water through the engine's cooling passages.

This reduces direct exposure of the engine's cooling passages to saltwater, sediment, and other contaminants.

The system is beneficial for riders who operate in freshwater and saltwater environments.

Proper flushing, cleaning, and scheduled maintenance remain essential for long-term ownership.

Distinctive Eclipse Black / Deep Marsala Styling
