- Open the raw water seacock.
- Reconnect the battery, start the engine, and immediately check for any leaks around the pump housing.
Troubleshooting & FAQ
How do I know if this impeller fits my engine?
Verify that your engine is a PCM or Crusader model from 2004 or newer with a serpentine belt driven raw water pump. Cross-reference your existing part number with the ones listed in the Part Number Matrix (RP061022, R061022, 18-8926, 9-45718) for confirmation.
What are the signs of a failing water pump impeller?
Common signs include the engine running hotter than normal, reduced water flow from the exhaust, visible cracks or missing blades on the old impeller, and a noisy water pump. Regular inspection is key to preventing overheating.
How often should I replace my impeller?
As a general rule, replace your raw water pump impeller at least once a year or every 100-200 hours of operation, whichever comes first. Refer to your engine's service manual for specific maintenance intervals.
