Riva Pro-Series Engine Cooling Upgrade Kit 1.8L SHO 2008-2016 RY10041-ECUK-PC

Riva Pro-Series Engine Cooling Upgrade Kit – Yamaha SHO

Part #: RY10041-ECUK-PC

Take your Yamaha SHO’s cooling system to the next level with the RIVA Pro-Series Engine Cooling Upgrade Kit. Engineered for high-performance applications, this kit dramatically improves cooling efficiency to both the engine and oil cooler—delivering enhanced performance and long-term reliability under extreme riding conditions.

By replacing the restrictive OEM pump strainer and fittings with high-flow billet components and optimized water routing, the system boosts both water flow and pressure. A specially designed billet fitting delivers cooling water directly into the engine block’s “hot spot,” where the factory zinc anode is located—an essential upgrade for modified watercraft running aftermarket ECUs, high-boost compressor wheels, or other heat-generating modifications.

Includes all waterlines, billet fittings, mounting hardware, and comprehensive installation instructions.
