Replacement impeller for late model MerCruiser V6 and V8 engines with brass water pumps

For 50 years Sierra has been producing parts engineered to meet or exceed the specifications of marine engine manufacturers and has gained the confidence of engine manufacturers and boat builders to a point of supplying them with OEM parts. Boaters and technicians can be assured a Sierra part will fit right the first time and restore function to OEM specifications.

Sierra impellers are designed and packaged to make replacement simple. Each impeller fits like an OEM part and includes a gasket to restore the wear plate seal. We recommend having a spare for unexpected failures caused by debris or clogged intakes.

Key Features

  • Engineered to meet or exceed OEM specifications
  • Kit includes impeller and gasket
  • Fits MCM 4.5L and MCM V6 and V8 (305, 350, 496) engines with brass sea water pump
