Troubleshooting & FAQ
What does this part do?
The wear plate provides the mating surface for the water pump impeller and helps the pump maintain the intended operating clearance. A worn or damaged plate can reduce water-pump performance.
How do I know if the wear plate needs replacement?
Inspect the plate whenever the water pump is serviced. Replace it if it is deeply scored, cracked, warped, excessively worn or otherwise damaged. Also inspect the impeller and pump housing before reassembly.
Is this a complete water pump kit?
No. This listing is for one water pump impeller wear plate only. The impeller, key, gaskets, seals, housing and other water pump components are not included unless specifically listed.
Does this replace Honda part number 19231-ZV5-000?
Yes. This replacement is listed for OEM reference 19231-ZV5-000. Compare the original part and confirm your complete engine identification before ordering.
Will it fit every Honda 35–50 HP outboard?
Fitment is associated with the BF35, BF40, BF45 and BF50 four-stroke model families. The available records do not establish every suffix, production year or serial-number range, so check your service documentation and original part number before purchase.
Should the impeller be replaced at the same time?
Inspect the impeller whenever the wear plate is replaced. If the impeller shows cracking, deformation, hardening or vane damage, replace it according to the applicable service procedure.
Is this an OEM Honda component?
No. This listing is for an aftermarket replacement. Honda and the OEM reference are mentioned only to identify the applicable part number and engine application.
Safety & Important Information
- Confirm the original part number, engine model, four-stroke configuration and applicable serial-number information before ordering.
- Do not rely on horsepower alone to determine fitment.
- Follow the engine manufacturer's service procedures and torque specifications during installation.
- Never operate the outboard without an adequate cooling-water supply.
- Professional installation is recommended if you are not familiar with lower-unit or water-pump service.
