- Close or drain the appropriate seacock and remove hoses or other components as required by the service manual.
- Remove the pump cover or applicable pump components, keeping track of the original component order and gasket locations.
- Remove the old impeller, wear plates, and gaskets. Inspect the housing and pump body for scoring, cracks, distortion, or corrosion.
- Clean all mating surfaces and remove old gasket material without damaging the sealing surfaces.
- Install the supplied wear plates, impeller, body gaskets, and water-pump gasket in the correct locations for the specific pump assembly.
- Lubricate the impeller with a suitable water-pump or glycerin-based lubricant before assembly. Do not run the pump dry.
- Reassemble the pump and tighten fasteners to the engine or pump manufacturer's specified torque.
- Reconnect hoses and open the seacock. Start the engine while monitoring cooling-water flow, temperature, and the pump area for leaks.
Always follow the service manual for the exact Bravo drive or engine configuration. If the pump housing or other reusable parts are damaged, additional replacement parts may be required.
Troubleshooting & FAQ
How do I confirm that this kit fits my MerCruiser?
Confirm that your existing water-pump assembly is a MerCruiser Bravo application and that its replacement reference is 46-807151A14 or 46-807151A7. Because Bravo configurations can vary, also compare the pump body, wear plates, gaskets, and impeller with the parts being removed.
Does this kit include the water-pump housing?
No. The referenced kit contents list wear plates, an impeller, body gaskets, and a water-pump gasket. A housing is not listed as included.
Does this kit include bolts or O-rings?
Bolts, washers, and O-rings are not listed in the referenced kit contents. Check the existing assembly and the applicable service manual to determine whether additional parts are needed.
What are the signs of a failing water-pump impeller?
Common symptoms include overheating, reduced cooling-water flow, and visible cracks, tears, stiffness, or deformation in the old impeller. Inspect the wear plates and housing at the same time because damaged surfaces can shorten the life of a replacement impeller.
How often should the impeller be replaced?
Inspect the impeller according to the engine manufacturer's maintenance schedule. Replacement intervals depend on operating hours, storage conditions, saltwater exposure, debris, and whether the pump has been run dry.
Is this an OEM part?
This listing is for an aftermarket water pump kit. MerCruiser part numbers are provided as replacement references only; the kit is not represented as a genuine MerCruiser-manufactured component.
Safety & Important Information
- Verify the application and component configuration before ordering or installation.
- Do not operate the engine without an adequate water supply to the pump.
- Replace damaged housings, pump bodies, fasteners, seals, or other components as required by the service procedure.
- Use the manufacturer's service manual for torque values, assembly order, and cooling-system bleeding procedures.
- Professional installation is recommended when the correct pump configuration or installation procedure is uncertain.
