This neoprene impeller is a critical component of your engine's cooling system, ensuring proper water flow to prevent overheating and maintain optimal engine performance.

  • Diameter: 2-5/8 inches
  • Depth: 1-13/16 inches
  • 6 flexible fins
  • Neoprene construction for durability
  • Keyed drive design

Sierra manufactures this impeller to meet or exceed original equipment specifications, ensuring a perfect fit and reliable performance. Impellers are subject to wear from sand, silt, and dry running conditions, making regular replacement an essential part of seasonal maintenance. Having a spare impeller on hand can prevent costly downtime and engine damage caused by cooling system failure.
