  • High-quality nitrile rubber construction for durability and chemical resistance
  • Precise OEM-equivalent dimensions for proper fit and performance
  • Compatible with multiple Sierra water pump kits for convenient servicing
  • Single impeller design for reliable water circulation
  • Engineered to meet or exceed original equipment specifications

Regular impeller replacement is essential preventive maintenance for marine engines.

A worn or damaged impeller can lead to engine overheating, reduced performance, and costly repairs.
