EXTENSION COQUE YAM SJ TR1
The Pro Watercraft Racing Drain Plug Holders are more than just a replacement for the factory drain plug surrounds…they’re a performance upgrade designed specifically for the 2021+ Yamaha 4-Stroke SuperJet. By extending and refining the water flow at the rear of the hull, these components help create a more planted feel on the water, improving stability, cornering confidence, and overall control. Whether you’re riding aggressively, carving tight turns, or spending the day on the lake, you’ll notice a more predictable and responsive ride. Constructed from our lightweight Hybird Flex Composite (HFC) material, these drain plug holders are built to withstand the demands of hard riding while maintaining a clean, factory-style appearance. These will fit the stock drain bungs but you can run the Yamaha specific Versiplug/Vacate Valve for easy draining.
