Features & Benefits |
-
The GP1800R SVHO is powered by Yamaha's 1.8L, supercharged Super Vortex High Output Marine engine, delivering more power and torque than any engine ever in a Yamaha WaveRunner personal watercraft.
-
Electronic Fuel Injection (EFI): Four electronically controlled fuel injectors, throttle position sensor (TPS) and intake air pressure and air temperature sensors supply the optimum air/fuel mixture. The results are a smooth, high power output with low fuel consumption and low exhaust emissions.
-
Specially Designed, One-piece Cylinder and Crankcase Assembly: Provides tremendous engine rigidity that's lighter and stiffer than two-piece designs.
-
Slant Detection Switch: Electronic switch stops engine and oil pumps immediately if watercraft becomes overturned, protecting motor from unwanted water ingestion.
-
Wet Sump Lubrication: Uses two engine oil pumps to deliver lubricated oil to each moving part with water-jacketed sump and oil backflow protection.
-
Yamaha Engine Management System (Y.E.M.S.): An integrated, computerized management system that controls and adjusts such functions as ignition timing, fuel injection mapping, engine diagnostics and off throttle steering (OTS). The OTS function of Y.E.M.S. activates when the operator releases the throttle lever and attempts to steer the watercraft. This assists the operator in turning while the watercraft is decelerating.
-
Independent Water-jacketed Exhaust Manifolds with Collector: Achieves high power while keeping noise and exhaust heat under control.
-
Thermostatic Cooling System: Water flow through the engine is automatically controlled through a thermostat sensor.
-
Corrosion Protection System: Sacrificial zinc anodes protect the engine from harmful galvanic corrosion. Stainless steel fasteners (nuts, bolts, hardware) provide a long service life. Cylinders, cases and heads are all treated with a durable oxide coating to form a barrier between corrosion and expensive engine parts.
-
Electronically Controlled, Variable Ignition Timing: For exact ignition advance control at all throttle positions and RPMs.
-
Direct Ignition: For more efficient combustion.

-
Ride (Reverse with Intuitive Deceleration Electronics) — The world's first dual handlebar throttle control system is easy and intuitive. Pull the right lever and go forward. Pull them both, or in any combination, and the system reacts with precise control. Benefits include better handling, smooth deceleration and more control while turning.
-
160mm, 8-vane high pressure pump: consists of a large capacity intake duct, a specifically developed impeller, a large diameter nozzle and other components matching the tremendous power created by the 1.8 litre supercharged super vortex engine. The GP1800R SVHO's jet pump has been upgraded for 2021 to allow less turbulent water to flow through the jet pump. The result is better acceleration and less cavitation in choppy water conditions. The GP1800R HO pump configuration provides excellent hook-up and quick acceleration.
-
The race-inspired ride plate and intake grate: Keep riders glued to the water, even at top speed. The dynamic shape of these items directs water flow into the pump for better thrust, performance and hook up.
-
Stainless Steel Impeller Housing Liner: For high durability, the liner maintains accurate clearance tolerances between the impeller and the housing.
-
Pumps are Manufactured with YDC30: A combination of zinc and copper alloys, developed by Yamaha marine engineers, that offers excellent corrosion protection.

-
The GP's hull design combines remarkably tight turning with an edge-to-edge inside-lean character that is as exciting as it is precise.
-
The GP1800R SVHO features Yamaha's second-generation NanoXel2 Hull and Deck. The result is a state of the art watercraft that is significantly lighter, making it quick and nimble, but with balance and manoeuvrability that truly connects the driver to the machine.
-
A redesigned hull liner moves the fuel tank 80mm towards the stern and 15mm lower in the hull. By repositioning the weight of the fuel tank, the craft’s new centre of gravity enhances the GPs’ nimble handling and agility.
-
Progressive, Stepper Draft V-Hull with Integrated Bow Spray Guard: Provides excellent manoeuvrability, handling and comfort.
-
Sponson Design: Provides added straight-line comfort and an improved two-up and three-up riding experience.
