Product Details

The Sierra 18-3311 is a complete water pump repair kit designed for Yamaha outboard engines. This comprehensive kit includes the water pump housing, making it ideal for complete water pump rebuilds on 150, 175, and 200 HP Yamaha outboards.

Complete Repair Kit Includes:

  • Water pump housing
  • Impeller cup
  • Impeller and impeller key
  • Wear plate
  • Gasket
  • O-rings
  • Stainless steel mounting bolts

Sierra engineers each component to meet or exceed OEM specifications, ensuring proper fit and reliable performance. This kit replaces Yamaha part numbers 6G5-W0078-A1-00, 6G5-W0078-00-00, and 6G5-W0078-01-00, as well as Mallory 9-48614. It is functionally equivalent to Sierra 18-3310 but includes the water pump housing for complete service.

Regular water pump maintenance is critical for preventing overheating and maintaining optimal engine performance. The water pump circulates cooling water through the engine block, and any restriction in water flow can result in power loss, reduced efficiency, and potential engine damage. This all-in-one kit eliminates the time spent sourcing individual components and ensures you have everything needed for a professional repair.
