How to Match This Part

This is a flexible rubber raw water pump impeller. It sits inside the pump housing behind the cover plate and is driven by a splined shaft. It replaces the primary original part number Jabsco 11979-0001, and is also supplied against JMP 7200-01, DJ 08-40-0801 and Yanmar 122610-42021.

Match this part by checking your engine in this order:
1. Original impeller part number (stamped on the old impeller or listed in the pump section of your parts catalog)
2. Blade count (this listing is 8 blades)
3. Drive type (this listing is a 12-spline hub, not a key drive)
4. Pump model (cast or labelled on the pump body — Jabsco 18930 / 18940 / 17200 family)

Identify it physically before ordering. This impeller has eight vanes moulded in black neoprene around a machined brass spline insert. JMP 7200-01 is 65 mm diameter, 37 mm width and 16 mm (5/8 in.) bore. Jabsco 11979-0001 is Profile M. It is not interchangeable with 12-blade 57 mm Jabsco 1210-0001 or 62.5 mm key-drive 18838-0001.

  • ✓ Primary OEM: Jabsco 11979-0001
  • ✓ Product form: 8-blade neoprene impeller, brass 12-spline insert, 37 mm width
  • ✓ Fitment: part number, then blade count, then drive type

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 gasket, O-ring and lubricant are not included. Jabsco 11979-0001-P and JMP 7200-01K 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, 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 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 spline orientation, then grip the brass insert and pull the old impeller straight off. Recover any broken vane pieces from the downstream cooling circuit 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 splines in the brass insert with the pump shaft, then press the impeller in while turning the shaft in the normal direction of rotation so all eight 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 a solid stream of cooling water 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. If the old part is Jabsco 11979-0001, JMP 7200-01, DJ 08-40-0801 or Yanmar 122610-42021, and the brass hub is a 12-spline drive about 37 mm wide on a 65 mm 8-blade impeller, this part is the correct size.

Will this fit every Yanmar inboard? +

No. Only engines whose parts list calls for 122610-42021. Yanmar 3JH / 4JH cooling impellers are a different size. Match the original number and count eight blades.

Is this the same as 12-blade Jabsco 1210-0001? +

No. 1210-0001 is 12-blade, 57 mm diameter and 31.5 mm wide. This listing is 8-blade, 65 mm diameter and 37 mm wide.

What are the signs that my impeller needs replacing? +

The usual symptoms are a weak or intermittent stream of cooling water, rising engine temperature, and vanes that are cracked, flattened, hardened or missing on inspection. Flexible impellers are a wear item; inspect 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 11979-0001-P and JMP 7200-01K are kit numbers that add a gasket, O-ring and lubricant.

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 seals and lubricant must be ordered separately if your service procedure requires them.
  • This is an 8-blade, 65 mm 12-spline impeller. It will not fit 12-blade 57 mm Jabsco 1210-0001 or 62.5 mm key-drive 18838-0001.
  • 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.
