Troubleshooting & FAQ
What are common signs of a failing water pump impeller?
Symptoms may include weak cooling-water flow, an overheating warning, reduced water pressure or visible impeller vanes that are cracked, brittle, deformed or missing.
How often should the impeller be replaced?
Replacement intervals depend on the engine manufacturer’s maintenance schedule and operating conditions. Inspect the impeller regularly and replace it when the service interval is reached or when wear, cracking or deformation is found.
Does this listing include a complete water-pump repair kit?
No. This listing is for one impeller only. Keys, gaskets, O-rings, bolts, wear plates, insert cups and housings are not included.
How can I confirm fitment?
Compare the complete engine model designation and the original impeller reference with the compatibility information above. If the model, stroke or original number differs, confirm compatibility with a qualified marine-parts specialist before ordering.
Is this an OEM Yamaha part?
No. This is an aftermarket replacement impeller associated with the listed Yamaha OEM references and aftermarket reference numbers.
Safety & Important Information
- Verify the exact engine model, stroke and original impeller reference before purchase.
- Do not operate an outboard with inadequate cooling-water flow or an overheating warning.
- Inspect the pump housing and related components during installation.
- Use the manufacturer’s service procedure and torque specifications for reassembly.
- This is an aftermarket replacement, not an OEM component.
