Troubleshooting & FAQ
How do I confirm this impeller fits my Yamaha outboard?
The best way is to verify your engine's model, year, and serial number against the compatibility tables on this page. You can also cross-reference your existing part number with those listed in the Part Number Matrix.
What are the signs of a failing water pump impeller?
Common symptoms include the engine overheating at idle or low speeds, a weak or non-existent water stream from the "telltale" outlet, and in some cases, a plastic or rubber burning smell from the exhaust.
What is the recommended replacement interval for this impeller?
As a preventative maintenance item, most manufacturers recommend replacing the water pump impeller every 1-2 years or every 100-200 hours of operation, whichever comes first. This can vary based on usage (saltwater vs. freshwater) and operating conditions.
Is the Woodruff key (90280-04002) included with this impeller?
No, the Woodruff key is required for installation but is sold separately. It is critical for locking the impeller to the driveshaft.
What is the difference between part numbers 6E5-44352-01 and 6E5-44352-00?
The part number 6E5-44352-01 is the official supersession for 6E5-44352-00. They are functionally identical, and this impeller replaces both versions.
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.
