Installation Notes

  1. Shut down the engine and close the raw-water intake seacock.
  2. Locate the raw-water pump and remove the end cover according to the pump manufacturer's service instructions.
  3. Remove the old impeller without damaging the pump housing or shaft.
  4. Inspect the housing, end cover, shaft, drive interface and sealing surfaces for wear or damage.
  5. Clean debris from the pump chamber and confirm that the replacement impeller matches the original diameter, width and drive configuration.
  6. Lubricate the impeller with a suitable water-compatible lubricant recommended for the pump application. Do not run the impeller dry.
  7. Install the impeller in the correct orientation for the pump's direction of rotation and refit the end cover using the correct seal or gasket for that pump.
  8. Open the seacock, start the engine and check immediately for leaks, overheating and proper exhaust-water flow.

Troubleshooting & FAQ

How do I confirm that this impeller fits?

Match the existing impeller's part number, diameter, width, shaft diameter and drive type. Also verify the pump model and pump part number. A shared engine brand or horsepower rating alone is not sufficient to confirm fitment.

What are common signs of a worn impeller?

Possible signs include reduced cooling-water flow, higher-than-normal engine temperature, an overheating alarm or damaged and missing impeller blades. Inspect the pump and cooling system before installing a replacement.

Does this listing include a gasket or O-rings?

No. This listing is for one replacement impeller. Gaskets, O-rings, keys and other service parts are not included unless expressly listed for the product being ordered.

How often should a flexible impeller be replaced?

Inspect the impeller at the interval specified by the engine or pump manufacturer. Replacement timing depends on operating hours, storage conditions, dry running and exposure to abrasive or contaminated water.

Is this an OEM impeller?

This is a JMP aftermarket replacement impeller. Jabsco, Detroit Diesel and Volvo Penta numbers shown on this page are manufacturer reference numbers used for identification and cross-reference.

Safety & Important Information

  • Close the seacock and allow the engine and pump to cool before servicing.
  • Do not operate the pump dry; dry running can quickly damage the impeller and pump.
  • Verify the pump model, part number and impeller dimensions before purchase and installation.
  • Replace damaged seals, gaskets or O-rings as required for the specific pump application.
  • Professional installation is recommended when pump or engine service procedures are unfamiliar.
