How to Match This Part

This is a flexible rubber raw water pump impeller for marine engine and generator sea water cooling pumps. It sits inside the pump housing behind the cover plate and is driven by a pin through a slotted shaft. It replaces the primary original part number Jabsco 22405-0001, and is also supplied against Johnson 09-808B, JMP 7000-01, DJ Pump 08-31-0601 and Cummins Onan 132-0310 / 132-0311.

Match this part by checking your engine in this order:
1. Original impeller part number (stamped on the old impeller box, or listed in the pump section of your engine parts catalog)
2. Raw water pump model (cast or labelled on the pump body, for example Jabsco 29300 / 52010 or Johnson F35)
3. Engine or generator model code (on the engine identification plate)

Identify it physically before ordering. This impeller has six straight vanes moulded in black neoprene rubber around a machined brass insert, and the bore uses a slotted-shaft pin drive on a 12 mm (15/32 in.) shaft. JMP lists 39.7 mm diameter, 19.2 mm width and 12 mm bore; DJ Pump and Jabsco catalogues round the same envelope to 40 mm × 19 mm. It is not interchangeable with Jabsco 4528-0001 / JMP 7001-01, which share the same outer size but use a smaller 9.5 mm (3/8 in.) shaft, or with JMP 7013-01, which uses a D-slot bore.

  • ✓ Primary OEM: Jabsco 22405-0001
  • ✓ Product form: 6-blade neoprene impeller, brass insert, 12 mm pin drive
  • ✓ Fitment: part number, then pump model, then engine model code

Compatible Engine Models

Confirm your engine model and the original impeller number in the table below. Because 22405-0001 and 4528-0001 share the same 40 × 19 mm envelope, always measure the shaft (12 mm vs 9.5 mm) and match the original part number before ordering.

Package Contents

This listing is for the impeller only, as shown in the product images. Please refer to the part number cross-reference table to confirm component details.

Cover plate gaskets, O-rings, cover screws and lubricant are not included. Genuine Jabsco 22405-0001-P and JMP 7000-01K kits add those service parts. If your service procedure calls for a new cover seal, order it separately against your pump model.

Installation Guide

  1. 1 Stop the engine or generator, let it cool, and close the raw water seacock so water cannot enter the boat while the pump is open.
  2. 2 Remove the cover plate screws from the sea water pump and lift off the cover. Keep the screws and the old gasket together so you can compare the seal size when reassembling.
  3. 3 Note the drive pin orientation, then grip the brass insert of the old impeller with an impeller puller or two flat-blade screwdrivers and pull it straight off the shaft. Recover any broken vane pieces from the heat exchanger inlet before continuing.
  4. 4 Clean the housing bore and the wear plate, and inspect them for scoring. Apply a marine-grade impeller lubricant, glycerine or soapy water to the bore and the new vanes. Do not use petroleum-based grease, which attacks neoprene.
  5. 5 Align the slot in the brass insert with the drive pin on the 12 mm pump shaft, then press the impeller in while turning the shaft in the normal direction of rotation so all six vanes lay over the same way.
  6. 6 Refit the cover plate with a serviceable gasket, tighten the screws evenly in a crisscross pattern, open the seacock, then start the engine and confirm steady water discharge and no leaks at the cover.

Note: Professional installation is recommended to ensure safety and optimal performance.

Troubleshooting & FAQ

How do I confirm this fits my engine? +

Start from the original impeller number rather than the engine alone. If your old part is listed as Jabsco 22405-0001, Johnson 09-808B, JMP 7000-01, DJ 08-31-0601, Onan 132-0310 or 132-0311, Volvo Penta 833995 or 875583-7, Westerbeke 32620 or 46622, Sierra 23-2001 or 23-3306, Vetus IMP00601 or CEF 500121, this impeller is the correct size. Then confirm a 12 mm (15/32 in.) pin-drive bore. A 9.5 mm shaft is Jabsco 4528-0001, not this part.

Is this the same as Jabsco 4528-0001? +

No. Both are six-blade Profile D neoprene impellers about 40 × 19 mm, but 4528-0001 uses a 9.5 mm (3/8 in.) shaft and 22405-0001 uses a 12 mm (15/32 in.) shaft. They are not interchangeable.

What are the signs that my impeller needs replacing? +

The usual symptoms are a weak or intermittent stream of cooling water at the exhaust outlet, rising coolant or exhaust temperature at low speed, and a high-temperature alarm on a generator set. On inspection the vanes may be cracked, flattened, hardened or missing. Flexible impellers are a wear item, so many owners inspect annually and replace on a fixed service interval rather than waiting for failure.

Is this a kit or just the impeller? +

This listing is the impeller only. Jabsco 22405-0001-P and JMP 7000-01K are kit numbers that add a cover gasket, O-ring and lubricant. Order those service parts separately if you need them.

Is this an OEM or aftermarket part? +

This listing is an aftermarket replacement part and is not an OEM component. We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.

How fast do you ship and how much does it cost? +

We offer fast global shipping, typically 5–15 days worldwide, and standard shipping is free. Expedited options are available at checkout depending on your location.

What is your warranty and return policy? +

This product includes a 1-year warranty against manufacturing defects under normal use. If something goes wrong, contact our support team with your order details. Returns are accepted within our standard return window for unused items in original condition; please see our policy page or reach out for instructions.

Important Notes

  • Verify that the product images and specifications match your original part. If discrepancies exist, even if your model is listed, do not proceed with the purchase.
  • This product is an aftermarket replacement part and is not an OEM component.
  • The impeller is supplied on its own. Cover plate seals, gaskets and lubricant must be ordered separately if your service procedure requires them.
  • Do not confuse this 12 mm pin-drive impeller with Jabsco 4528-0001 (9.5 mm / 3/8 in. shaft) or JMP 7013-01 (D-slot, 12 mm shaft).
  • Never run the pump dry. Even a few seconds without water will damage the neoprene vanes.
  • Professional installation is recommended to ensure safety and optimal performance.
