Installation Notes

  2. Place the outboard in neutral and drain the lower unit gear lube.
  3. Remove the bolts securing the lower unit (gearcase) to the upper casing and carefully lower it.
  4. Unbolt and remove the water pump housing to access the impeller.
  5. Take note of the old components' orientation before removing the old impeller, key, wear plate, and gaskets.
  6. Clean all mounting surfaces thoroughly, removing any old gasket material or sealant.
  7. Install the new wear plate, gaskets, impeller key, and impeller. Lubricate the new impeller and housing interior.
  8. Reinstall the water pump housing, torquing bolts to manufacturer specifications.
  9. Re-attach the lower unit, ensuring the driveshaft and water tube align correctly.
  10. Refill the gearcase with fresh lube, reconnect the battery, and test the engine with a proper water supply. Check for a strong, steady stream from the tell-tale port.

Troubleshooting & FAQ

How do I know if this water pump kit will fit my engine?

The most reliable method is to match your engine's model and year to our compatibility table. If your model is listed, this kit is a confirmed fit. Avoid matching by horsepower alone, as different models can share the same power rating but use different parts.

What are the signs of a failing water pump impeller?

Common symptoms include a weak or intermittent water stream from the tell-tale (water discharge) port, engine overheating alarms, or visible steam from the exhaust. A damaged impeller cannot provide sufficient cooling water to the engine.

How often should I replace my impeller?

As a general maintenance rule, it is recommended to inspect and/or replace the water pump impeller every 1 to 2 years or every 100-200 hours of use, whichever comes first. This interval can be shorter if you frequently operate in sandy, silty, or saltwater conditions.

Is everything I need for the job included in this kit?

Yes, this is a comprehensive repair kit that includes the impeller, wear plate, insert cup, gaskets, o-ring, key, and all necessary bolts and washers for a complete water pump overhaul.

Can I install this kit myself?

Many boat owners with mechanical experience can perform this replacement. However, it requires lowering the gearcase and following specific torque sequences upon reassembly. If you are not comfortable with this process, we recommend professional installation to ensure safety and proper function.

OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
