4. With the lower unit removed, locate and unbolt the water pump housing.
5. Remove the old impeller, gaskets, wear plate, and seals from the housing and driveshaft.
6. Thoroughly clean all mating surfaces, removing any old gasket material or debris.
7. Install the new wear plate, gaskets, and impeller key onto the driveshaft.

10. Carefully reinstall the lower unit, ensuring the driveshaft and water tube align properly.
11. Refill the gearcase with fresh marine gear oil.

Troubleshooting & FAQ

How do I confirm this fits my Honda engine?

This kit is specifically designed for Honda BF35, BF40, BF45, and BF50 4-stroke models from all production years. To ensure a perfect match, please check your engine model against the "Compatible Engine Models" list and verify that your existing part number is 06193-ZV5-020, 06193-ZV5-010, or 06193-ZV5-000.

What are the signs of a failing water pump impeller?

Common symptoms of a worn or damaged impeller include the engine overheating (especially at idle), a weak or intermittent stream of water from the "tell-tale" cooling outlet, or a complete lack of water discharge. In some cases, you may find bits of rubber from the old impeller clogging the cooling passages.

How often should I replace my water pump service kit?

As a critical preventative maintenance item, it is recommended to inspect the impeller annually and replace the entire water pump kit every 2-3 years or 200-300 hours of use, whichever occurs first. This interval can be shorter if the engine is operated frequently in saltwater or sandy/silty conditions.
