Technical Specifications

Package Contents

• 1 x Water Pump Impeller (6CE-44352-00-00)

Note: When purchasing a complete water pump repair kit separate from just the impeller, additional components are included such as gaskets, plates, bolts, O-rings, and seals.

Installation Guide

1. Safety First: Disconnect the engine's battery cables to prevent accidental starting.
2. Lower Unit Removal: Place the outboard in neutral. Remove the bolts securing the lower unit (gearcase) to the engine. There is typically one hidden under the trim tab anode.
3. Detach Lower Unit: Carefully lower the gearcase away from the engine. The driveshaft will disengage from the powerhead.
4. Access Impeller: Locate the water pump housing on top of the gearcase. Remove the bolts holding the housing cover in place.
5. Remove Old Impeller: Lift off the housing. You can now see the old impeller. Remove it from the driveshaft, being careful not to lose the Woodruff key that aligns it.
6. Clean & Prep: Thoroughly clean the inside of the pump housing and the wear plate. Lightly lubricate the new impeller and housing interior with marine grease or soapy water.
7. Install New Impeller: Slide the new impeller onto the driveshaft, ensuring it aligns with the Woodruff key. Twist the driveshaft clockwise while pushing down on the housing to fold the blades correctly.
8. Reassemble: Secure the water pump housing with its bolts. Re-install the lower unit, making sure the driveshaft, shift shaft, and water tube align properly before bolting it back on.
9. Final Check: Re-install the trim tab anode and reconnect the battery. Start the engine using a water supply (flushing muffs) and check for a strong stream from the water pump tell-tale outlet.

Troubleshooting & FAQ

Q: How do I confirm this impeller fits my specific engine?

A: The best way is to match your engine's model and year against the compatible models list on this page. For absolute certainty, cross-reference the OEM part number 6CE-44352-00-00 with your existing part or your engine's service manual.

Q: What are the signs of a failing water pump impeller?

A: The most common indications include a weak or intermittent water stream from the tell-tale outlet, or the engine overheating alarm sounding. Upon inspection, a worn impeller may have cracked, brittle, or broken blades.

Q: How often should I replace my water pump impeller?

A: As a general rule, it is best practice to inspect your impeller annually and replace it every 1-2 years or every 100-200 hours of operation, whichever comes first. This interval can be shorter if you frequently operate in sandy, silty, or saltwater conditions.
