Installation Guide
-
Safety First: Close the boat's seacock (raw water intake valve) before beginning.
-
Access the Pump: Loosen the serpentine belt to relieve tension from the raw water pump pulley.
-
Remove Housing: Unscrew the bolts that secure the water pump's front cover housing. Keep the bolts and cover nearby.
-
Note Blade Direction: Before removal, look closely or take a photo of the direction the old impeller's blades are bent. The new one must be installed the same way.
-
Remove Old Impeller: Use impeller pullers or two pairs of pliers to grip the hub and pull the old impeller straight out of the housing.
-
Clean and Inspect: Thoroughly clean the inside of the pump housing. Check for any scoring, cracks, or deep grooves that could cause leaks or damage the new impeller.
-
Lubricate: Lightly lubricate the inside of the pump housing and the new impeller with a water-based lubricant or a small amount of dish soap.
-
Install New Impeller: Push the new impeller into the housing while twisting it in the direction of engine rotation to fold the blades correctly. Match the folded direction you noted in step 4.
-
Replace Seals: Install the new housing O-ring (R047242) and the four bolt O-rings (R047243) on the cover screws.
-
Reassemble: Re-secure the pump housing cover, tightening the bolts in a star pattern to ensure an even seal. Do not overtighten.
-
Tension Belt: Re-tension the serpentine belt to the manufacturer's specification.
-
Check Your Work: Open the seacock. Start the engine and immediately check for any water leaks around the pump housing and confirm water is flowing out of the exhaust.
Troubleshooting & FAQ
Q: How do I know if this impeller kit fits my PCM or Crusader engine?
A: This kit is specifically for PCM and Crusader engines manufactured from 2004 onwards that use a serpentine belt-driven raw water pump. The best way to confirm is to check your engine's pump model (e.g., RA057032, RA057034) or cross-reference your existing impeller's part number with RP061022 or R061022.
Q: What are the signs of a failing impeller?
A: The most common signs are engine overheating at idle or low speeds, a noticeable reduction in water flow from the exhaust, or visible signs of damage on the old impeller such as cracks, missing blades, or a stiff, brittle texture.
Q: How often should I replace my water pump impeller?
A: As a general rule for preventative maintenance, it is recommended to inspect the impeller annually and replace it every 1-2 years or every 100-200 hours of operation. This interval may be shorter if you operate primarily in saltwater or silty/sandy conditions.

A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.
