Troubleshooting & FAQ
How do I know if my water pump impeller needs replacing?
Common signs include a weak or intermittent tell-tale stream, overheating warnings, reduced cooling-water flow, or visible cracking, brittleness, deformation, or vane wear during inspection.
Is the water pump key included?
No. This listing is for the impeller only. The key is a separate component and should be inspected and replaced separately when necessary.
Will this fit a Yamaha 4-stroke F-series engine?
Do not assume that it will. The documented applications for this part number include Yamaha 2-stroke models. Confirm the exact OEM impeller number and complete engine model before installation.
What's the difference between this and a full water pump kit?
This listing contains one impeller only. A complete water pump kit may also include a key, housing, wear plate, gaskets, O-rings, cup, or other hardware. Those components are not included unless specifically listed.
Can I run the engine dry after installing the new impeller?
No. Never run an outboard without an adequate water supply. A dry start can quickly damage the impeller and may lead to overheating.
Is this an OEM component?
This is an aftermarket replacement impeller. Yamaha OEM part number 6E5-44352-01-00 and Sierra reference 18-3071 are provided for identification and cross-reference only.
Safety & Important Info
- Verify the complete engine model, year, serial-number range, original part number, and impeller dimensions before ordering.
- Do not rely on horsepower alone to confirm compatibility.
- Inspect the water pump housing, wear plate, key, and gaskets during installation.
- Professional installation is recommended when lower-unit or cooling-system service is unfamiliar.
- This is an aftermarket replacement, not a Yamaha OEM component.
