PRODUCT INFORMATION
The RIVA Pro-Series Waterbox is a high-flow aluminium waterbox for Yamaha 1.8L SVHO, SHO and HO and 1.9L HO WaveRunners. Radiused tubes and end caps improve exhaust flow, and a tuned baffle adds low-end power and mid-range pull. RIVA quotes up to 15 hp on modified engines, plus torque gains.
It is built for owners of modified skis, and the strong aluminium body survives backfires. Powder coated against corrosion. RIVA notes it is not compatible with free flow exhaust kit RY16200 on 2024 and newer FX, GP and VX HO 1.9L models.
