Product Details
This flexible impeller kit is designed as a replacement for marine raw-water cooling pump applications using Jabsco 1210-0001 or Johnson 09-1027B impellers. It is also listed as a replacement for Volvo Penta references 21951346, 3862281 and 3858256.
The kit is intended for service or replacement of the impeller in compatible seawater and raw-water pumps. Always compare the part number, pump configuration and dimensions of your existing impeller before ordering.
- Direct replacement design for compatible pump housings.
- Neoprene construction for raw-water engine-cooling applications.
- Includes the impeller and the listed sealing components for service installation.
- Compatibility depends on the pump and the applicable manufacturer part number, not on engine brand alone.

Installation Notes
- Turn off the engine, allow it to cool, and close the raw-water intake seacock.
- Place an absorbent towel below the seawater pump to catch spills.
- Remove the screws securing the pump end cover.
- Remove the old impeller with suitable pliers or an impeller puller. Note the direction of the vane bend.
- Clean the pump chamber and inspect the housing, cover plate and shaft for scoring or damage.
- Select the gasket or O-ring that matches the pump cover and the removed seal.
- Lightly lubricate the new impeller with a water-based lubricant or liquid soap. Do not run the pump dry.
- Install the impeller with the vanes bent in the same direction as the original, normally following the pump's direction of rotation.
- Reinstall the cover and tighten the screws evenly.
- Open the seacock, start the engine and check immediately for proper water flow and leaks.
Troubleshooting and FAQ
How do I know if the impeller needs replacing?
Common signs include higher-than-normal engine temperature, reduced water flow from the exhaust, visible cracks or stiffness, and missing or damaged vanes.
How often should I replace the impeller?
Inspect the impeller at least annually. Replacement intervals depend on use, storage conditions and the pump manufacturer's maintenance schedule; replace it sooner if the vanes are damaged, permanently set or deteriorated.
Which gasket should I use when the kit includes multiple gaskets?
Compare each gasket with the pump end cover and the removed gasket. Use the one that matches the sealing surface exactly; unused alternatives should not be stacked or substituted without confirming the pump design.
Can I run the raw-water pump dry?
No. Water lubricates and cools the impeller. Dry running can quickly damage the neoprene vanes and the pump.
What is the difference between a neoprene and a nitrile impeller?
Neoprene is commonly used for raw-water engine-cooling applications. Nitrile is generally selected for fluids containing petroleum products. Use the material specified for your pump and application.
Will it fit if my engine year is outside the listed range?
Fitment is not guaranteed solely by engine model or year. Confirm the pump configuration and match the applicable manufacturer part number before ordering.
Is this an OEM part?
This listing is for an aftermarket replacement. The referenced manufacturer names and part numbers are used only to identify compatibility and replacement applications.
How should I confirm compatibility?
Match the part number, impeller dimensions, drive configuration and sealing arrangement to your original component and pump documentation. If any critical detail differs, do not install the part until compatibility has been confirmed.
Safety and Important Information
- Close the raw-water seacock and allow the engine to cool before servicing the pump.
- Verify the part number and dimensions against the original impeller and pump.
- Do not operate the raw-water pump without an adequate water supply.
- Inspect the pump housing, cover plate, shaft and seal after removing the old impeller.
- Professional installation is recommended when the pump or engine service procedure is unfamiliar.
