Gallery: RIVA Racing's Special Edition 2023 Yamaha GP1800R SVHO

RIVA has built a powerful Limited-Edition Yamaha GP1800 SVHO that is only available by special order. The watercraft comes in an eye-catching blue with spicy red accents and glossy red anodized components. The components stand out, adding to the stellar look of this machine with the red stitching in the custom seat cover rounding out the look.

This custom unit is equipped with a powerful engine that produces 350 horsepower and can hit a top speed of 86mph. The build is flashed with a Maptuner X Tuning License, which allows for that top speed of 86mph at 8,600rpm. The billet aluminum RIVA Yamaha 1.8L High Flow Billet Fuel Rail helps to provide this machine with boosted horsepower by replacing the restrictive factory fuel rail. It looks good too!

The RIVA Yamaha GP1800R SVHO Power Filter Kit further adds to improved acceleration and rpm. The power filter kit provides a constant flow of cool air to the supercharged engine. The RIVA Yamaha 1.8 Catch Can eliminates power-robbing crankcase fumes and oil fumes from entering the engine’s air intake and it prevents oil sludge.

The RIVA Yamaha Supercharger Shaft Upgrade Kit utilizes a hydraulic shaft stabilization bearing that limits shaft deflection and wear. High pressure oil film is fed through the shaft, maximizing lubrication to keep your watercraft s running smooth.

A high-performance watercraft has to be kept super cool so RIVA outfitted the SE with their Riva Yamaha GP1800R SVHO Gen-3 Power Cooler. It is built to keep this powerful watercraft cool up to 600hp! The component features a high-capacity cooler core than can resist heat, no matter how hard you ride.

It also provides an increase of 20 peak hp over OEM intercoolers. It runs an average of 50F cooler than stock on exit, thus increasing performance. It comes with the 50mm TIAL Blow-Off Valve for even better performance and reliability.

The cooling wouldn’t be complete without the RIVA Yamaha SVHO Pro Series Engine Cooling Upgrade Kit. The kit provides improved cooling efficiency to the engine and inter-cooler for increased performance. The high-flow billet pump strainer increases water flow, and the billet engine fitting injects water into the engine block’s hotspot. The RIVA crew added their titanium Yamaha 1.8L Valve Retainer Upgrade Kit to reduce the possibility of valve float at high rpm.

The SE wouldn’t be complete without the RIVA branded silicone Rear Exhaust Kit. This kit not only looks good, but it delivers outstanding performance and adds cutting edge style to any PWC.

Installing the rear exhaust kit allows for the removal of the restrictive sound suppression system. Engine performance is also greatly improved because back pressure is reduced as well. The engine components are topped off with a red anodized aluminum RIVA Yamaha 1.8L Billet Engine Oil Filler Cap.

A race ready machine like the RIVA Special Edition Yamaha must have upgraded steering and handling components so the rider can control this beast. A Solas Yamaha 160mm 13/18 Concord Impeller replaces the stock impeller. It is large and in charge, delivering increased acceleration and top speed with its large blade area. It reduces cavitation too enabling you to have more control.

Another component that reduces cavitation and prop spin is the RIVA Yamaha Gen-2 GP1800 SVHO Pump Seal Kit. The RIVA Yamaha Gen-2 GP1800 SVHO Top-Loader Intake Grate also helps with control as it significantly reduces cavitation and gives you the confidence to stay on the throttle even in extreme conditions.

The addition of the RIVA Yamaha GP1800 Ride Plate adds to the superior handling of the SE with its deep center skeg and channels for excellent traction in turns. Its extended length provides quicker planning and improved acceleration.

The RIVA Yamaha GP 1800 Pro-Series Sponsons will keep you charging in a straight line with their superior fin and backing fin design. Set them up how you like them with the fully adjustable three-position fin. Now onto the incredible steering components.

The standout RIVA Yamaha GP1800R Pro-Series Steering System is the ultimate for racing. The billet aluminum construction has superior strength and rigidity over bulky stock systems. This steering system is a must have if you want to have absolute control over a powerful watercraft like the custom RIVA Yamaha GP1800R, which is specifically built for racing.

The RIVA Pro-Bar 30” Runabout Handlebars are an excellent addition to the RIVA SE Yamaha. They are built with a proprietary T6 aluminum alloy for superior tensile strength and vibration dampening, which are much needed when racing. Rounding out the handlebars are the ODI Rogue Lock-On Grips, 130MM, No Flange and the ODI Grip End Cap and Clamp Kit. The grips offer a 100% slip-free performance and the end caps keep your grips locked on.

That sums up RIVA’s latest custom build. The RIVA Special Edition 2023 Yamaha GP1800R SVHO is another stellar in-house build from the master technicians of RIVA Racing. RIVA says this watercraft will make heads turn and will make you the envy of any racecourse or local riding spot with its unique styling.
