Installation Guide

1. Turn off the engine and close the raw water intake seacock.
2. Loosen the serpentine belt to relieve tension from the raw water pump pulley.
3. Remove the bolts securing the pump housing cover. Note their positions if they are different lengths.
4. Take note of the blade orientation before carefully removing the old impeller. Needle-nose pliers or an impeller puller may be helpful.
5. Clean the inside of the pump housing of any debris or old blade pieces.
6. Lightly lubricate the new impeller and the inside of the housing with water-resistant grease or dish soap.
7. Install the new impeller by squeezing the blades together and rotating it into the housing. Ensure the blades bend in the same direction as the old impeller.
8. Replace the housing O-ring (R047242) and the bolt O-rings (R047243).
9. Re-secure the housing cover and tighten the bolts in a crossing pattern to ensure an even seal.
10. Reinstall and correctly tension the serpentine belt.
11. Open the raw water seacock.
12. Start the engine and immediately check the pump for any leaks and verify strong water flow from the exhaust.

Troubleshooting & FAQ

Q: How do I confirm this fits my engine?
A: This impeller fits PCM and Crusader engines (5.0L to 8.1L) manufactured from 2003 to present that use a serpentine belt-driven raw water pump. It is not compatible with older V-belt systems. Cross-reference your existing part number with RP061022, R061022, 18-8926, or 9-45718 to ensure a match.

Q: What are the signs of a failing impeller?
A: Common signs include the engine running hotter than normal, a noticeable reduction in water flowing from the exhaust, visible cracks or missing blades on the old impeller, or an impeller that has become stiff and brittle.

Q: How often should I replace my raw water pump impeller?
A: As a critical maintenance item, the impeller should be inspected annually. We recommend replacing it every 1-2 years or every 100-200 hours of engine operation, whichever comes first, to prevent unexpected failure.
