Yamaha 2026 WaveRunner GP HO (High Output)

Do you want supercharged top speed, or big naturally aspirated displacement with a simpler service interval? The Yamaha GP HO WaveRunner for sale here answers with the second option: a 1.9L High Output engine at 1,898cc, four cylinders, DOHC, 16 valves, feeding a 155mm high-pressure axial flow pump through a race-designed top-loader intake grate. Verified brand new, zero break-in needed.

What a technician finds under the hood

Induction is naturally aspirated with a 10% enlarged throttle body for immediate, linear response, backed by EFI tuned for standard unleaded. Lubrication runs dual-pump wet-sump with open-loop raw water cooling, and an upgraded water-cooled regulator/rectifier protects the electrical components long-term. RiDE’s reverse bucket is throttle-by-wire, which means no mechanical reverse cables or linkages to maintain.

What the hull and controls give a rider

NanoXcel2 hull material runs up to 18% lighter than traditional SMC without losing rigidity, shaped into a deep-V keel with redesigned bow chines and side strakes for tracking precision and soft-entry wave handling. Auto Trim adjusts nozzle angle automatically: Cornering Control drops the bow under deceleration to dig into sharp turns, and Launch Control checks bow rise under hard acceleration. Handlebars are tilt-adjustable and race-inspired, built for both seated carving and stand-up riding.

Comfort, storage and security

Seating is race-textured, tiered for three, with deep knee bolsters to hold riders in place through aggressive maneuvers. Footwells self-drain whether the craft is moving or moored. Storage runs across bow space, a high-volume watertight glovebox with USB/12V outlets, and under-seat dry storage. The 4.3-inch Connext touchscreen carries PIN-code security, customizable acceleration profiles, real-time trip data and full diagnostic readout.

Riders weighing the supercharged option should buy the Yamaha GP SVHO Solid Black instead, and the same naturally aspirated 1.9L engine also appears in the Yamaha VX Cruiser HO price if a cruiser seat matters more than a race hull. The full WaveRunner lineup for sale is grouped in one category, and anyone kitting the craft out can buy WaveRunner accessories online from the same yard.
