🔌 Function

The impeller rotates inside the lower-unit pump housing to draw cooling water into the engine. A correct impeller helps maintain water pressure, prevents overheating and supports reliable cooling at idle, low speed and operating RPM.

⚠️ Common Signs of Failure

  • Weak or inconsistent tell-tale water stream
  • Engine overheating warning
  • Pump not priming after service or storage
  • Cracked, stiff or damaged impeller vanes
  • Reduced cooling-water pressure
  • Rubber fragments found in the cooling system
