Troubleshooting & FAQ
What does this product replace?
The available catalog identifies Sierra 18-3214 as replacing Force part number 46-43024A7.
Is this a complete water-pump housing assembly?
No complete housing assembly is established by the available product evidence. The item is identified as an impeller repair kit. Confirm the package contents before installation.
Will this fit every Mercury, Mariner, or Force 8–25 HP engine?
No broad 8–25 HP fitment claim is confirmed for this specific product entry. Brand and horsepower alone are insufficient; verify the exact model, year, serial number, and original pump components.
Does the kit include a gasket, key, wear plate, or housing?
The available catalog entry does not itemize the contents of this kit. Do not assume that these components are included unless they are shown in the package or confirmed before purchase.
Is this an OEM part?
This listing represents an aftermarket replacement identified by the Sierra catalog number 18-3214. It is not presented as a genuine OEM component.
How often should an impeller be replaced?
Inspect the impeller according to the engine manufacturer's maintenance schedule and whenever cooling performance is reduced. Replace it sooner if the engine has been run without adequate water flow or if the impeller shows cracking, hardening, deformation, or vane damage.
Safety & Important Information
- Verify the exact model, year, serial number, original part number, and pump configuration before ordering.

- Do not operate an outboard with inadequate cooling-water flow.
- Follow the engine manufacturer's service manual for removal, installation, clearances, and torque specifications.
