Product Details
This Sea Sierra Water Pump Impeller Kit is an aftermarket replacement service kit for selected MerCruiser drive-mounted sea water pumps with a one-piece pump body. Catalog references identify this configuration as an upper sea water pump housing impeller kit for a MerCruiser one-piece pump. Confirm the pump-body design and the part number on your original component before ordering.
This kit replaces the MerCruiser reference 47-59362T6. The reference is used to identify the application and is not a statement that this aftermarket product is manufactured by Mercury Marine.
- Designed for service of compatible one-piece MerCruiser sea water pump assemblies.
- Suitable for replacing a worn or damaged raw-water-pump impeller when the pump housing and drive configuration match.
- Application depends on the complete pump assembly, drive, and serial-number range; engine displacement alone is not sufficient for fitment.
Part Number Reference
Use the following manufacturer reference to compare against the part removed from your pump.
| Brand | Part Number |
|---|---|
| MerCruiser | 47-59362T6 |
Engine & Pump Compatibility
This product should be selected by pump configuration and verified reference number rather than by a broad engine-size range. Catalog information associates the reference with a drive-mounted impeller kit for a MerCruiser one-piece sea water pump. Other MerCruiser pump designs, including two-piece housings and different drive-mounted service kits, use different impeller references.
| Application | Configuration | Reference | Fitment Requirement |
|---|---|---|---|
| MerCruiser drive-mounted sea water pump | One-piece pump body | 47-59362T6 | Verify the original pump and impeller reference before installation |
| MerCruiser Alpha or Bravo-related applications | Varies by pump design, drive, and serial number | Not confirmed solely by engine model | Do not order without matching the complete pump configuration |

Installation Notes
- Disconnect the battery and close the seacock or sea strainer valve before beginning service.
- Verify that the pump body is the one-piece configuration and compare the existing impeller with the replacement.
- Locate the sea water pump and note the hose routing and connection locations before removal.
- Remove the necessary hoses, fasteners, cover, or pump components according to the engine and pump manufacturer's service procedure.
- Remove the old impeller with a suitable impeller puller or removal tool. Avoid damaging the pump housing, shaft, and sealing surfaces.
- Clean the housing and inspect it for scoring, cracks, distortion, or debris. Replace damaged pump components before installing the new impeller.
- Lubricate the impeller and sealing surfaces with a suitable marine lubricant compatible with the pump manufacturer's instructions. Do not run the pump dry.
- Install the impeller in the correct rotational direction and reinstall the cover and any supplied sealing components.
- Reinstall the pump, reconnect the hoses, open the seacock, and restore the cooling-water supply.
- Start the engine only with adequate water supply. Check immediately for water flow, leaks, abnormal noise, and proper operating temperature.
Troubleshooting & FAQ
How do I know if this impeller kit fits my engine?
Confirm that your engine uses a MerCruiser drive-mounted sea water pump with a one-piece pump body and that the existing impeller or pump reference is 47-59362T6. Engine displacement, model family, or drive name by itself does not confirm fitment.
What are the signs of a failing water pump impeller?
Common signs include higher-than-normal engine temperature, reduced cooling-water flow, overheating at idle or low speed, and cracked, torn, stiff, or permanently deformed impeller blades when inspected.
How often should the impeller be replaced?
Inspect the impeller according to the engine manufacturer's maintenance schedule and replace it when the blades show wear, cracking, hardening, deformation, or damage. Frequent use in saltwater, sandy water, or other contaminated conditions may require more frequent inspection.
What can cause premature impeller failure?
Common causes include operating the pump without an adequate water supply, abrasive sand or debris, extended storage, corrosion, incorrect installation direction, and a worn or damaged pump housing.
Is this an OEM part?
No. This is an aftermarket replacement service kit referenced to MerCruiser 47-59362T6. It is not manufactured or branded by Mercury Marine.
What should I verify before ordering?
Match the pump-body design, drive-mounted configuration, original reference number, and available serial-number information. If the pump is a two-piece design or the reference does not match, select the service kit specified for that assembly instead.
Safety & Important Information
- Never operate a raw-water pump without an adequate water supply.
- Verify the complete pump configuration and original reference before purchase and installation.
- Inspect the pump housing, cover, shaft, wear surfaces, and sealing surfaces during service.
- Follow the engine and pump manufacturer's service instructions and torque specifications.
- This is an aftermarket replacement, not an OEM component.
- Professional installation is recommended when the pump assembly or engine service procedure is unfamiliar.
