Installation Guide

  1. Safety First: Disconnect the engine's battery cables before beginning work.
  2. Access the Lower Unit: Remove the bolts securing the gearcase (lower unit) to the midsection and carefully lower it.
  3. Open the Pump Housing: Locate the water pump assembly on top of the gearcase. Remove the bolts holding the pump cover.
  4. Remove Old Impeller: Slide the old impeller off the driveshaft. Note the direction of the vanes; the new ones must face the same way.
  5. Clean and Inspect: Clean any debris from the pump housing, wear plate, and cover. Inspect for scoring or damage.
  6. Install New Impeller: Lightly lubricate the new impeller and housing. Slide the new impeller onto the driveshaft while turning the shaft clockwise to bend the vanes correctly.
  7. Reassemble Pump: Secure the pump housing cover, ensuring any seals or gaskets are properly seated.
  8. Reattach Lower Unit: Reinstall the lower unit, making sure the driveshaft, shift shaft, and water tube align correctly. Torque bolts to manufacturer specifications.
  9. Test Operation: Reconnect the battery. Start the engine using a water supply (flushing muffs) and verify a steady stream of water from the tell-tale port.

Troubleshooting & FAQ

How do I confirm this fits my engine?
Verify your engine's horsepower, stroke, and year fall within the ranges listed in the Compatible Engine Models table. Cross-reference your existing part number with those in our Part Number Cross-Reference table for confirmation.
What are the signs of a failing water pump impeller?
Common symptoms include the engine overheating, a weak or non-existent water stream from the "tell-tale" outlet, and a melted water pump housing. Failure to replace a worn impeller can lead to severe engine damage.
How often should I replace the impeller?
For preventative maintenance, it is recommended to replace the impeller every 1-2 years or every 100-200 hours of operation, whichever comes first. More frequent replacement may be necessary if you operate in sandy or silty water.
