Troubleshooting & FAQ
How do I confirm that this impeller fits my Yamaha outboard?
Confirm that your engine is a Yamaha 2-stroke model designated 6A, 8A or P165 and compare the existing impeller and OEM reference 655-44352-09-00. Because fitment may also depend on shaft configuration or serial range, consult the engine service information when those details are available.
What are the signs of a worn or failed impeller?
Possible signs include reduced or absent cooling-water discharge, overheating, steam or abnormal temperature. Stop operating the engine if cooling flow is inadequate and inspect the water-pump system before further use.
Should the pump housing and seals also be inspected?
Yes. A new impeller may not restore proper water flow if the housing, wear plate, drive key, gaskets or seals are worn, damaged or incorrectly installed.
Is this a complete water-pump kit?
No. This listing is for one replacement impeller only. Other water-pump components are not included unless specifically listed with the order.
Is this an OEM Yamaha part?
This is a replacement impeller for the listed application. Yamaha and the referenced OEM part number are used only to identify the intended fitment and comparison reference.
Safety & Important Information
- Verify the engine model, stroke, shaft configuration and applicable serial information before ordering.
- Compare the replacement impeller with the original part before installation.
- Use the service procedure and tightening specifications for your exact outboard.
- Professional installation is recommended if you are not familiar with lower-unit or water-pump service.
