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 17936-0001, and is also supplied against Jabsco 21676-0001, JMP 8301-01, Johnson 09-814B / 08-814B and DJ 086-1201.

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 12 blades — not the 9-blade 8200-01 of the same envelope)
3. Drive type (this listing is a 12-spline hub, 25 mm bore)
4. Width (this listing is about 89 mm wide, not the 63 mm 95 mm-diameter family)

Identify it physically before ordering. This impeller has twelve vanes moulded in black neoprene around a machined brass 12-spline insert. JMP 8301-01 is 95 mm diameter, 88.8 mm width and 25 mm bore. It is not interchangeable with 9-blade 8200-01 / 6760-0001 of the same envelope, or with 63 mm-wide 8100-01 of the same diameter.

  • ✓ Primary OEM: Jabsco 17936-0001
  • ✓ Product form: 12-blade neoprene impeller, brass 12-spline insert, 88.8 mm width, 25 mm bore
  • ✓ Fitment: part number, then blade count, then width

Part Number Cross-Reference

Use this table to confirm equivalent part numbers. JMP 8301-01K is a kit number. This listing is the impeller only. Perkins 0460027 also appears on the 9-blade 8200-01 listing — count twelve blades before using that number here.

Package Contents

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

Cover gasket, O-ring and lubricant are not included. JMP 8301-01K adds gasket GAK0007, O-ring ORG0015 and lubricant; kit extras are not included.

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 spline 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 twelve 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 17936-0001 or 21676-0001, JMP 8301-01, Johnson 09-814B / 08-814B, DJ 086-1201, Yanmar 165000-35720, Onan 008503, CAT 4L8470 or Northern Lights 25-15003, and the brass hub is a 25 mm 12-spline about 89 mm wide on a 95 mm 12-blade impeller, this part is the correct size.

Is this the same as 6760-0001 / 8200-01? +

No. Those numbers are 9-blade impellers of the same 95 × 88.8 mm envelope. This listing is 12 blades. Count blades before ordering.

Is this the same as 17935-0001 / 8100-01? +

No. Those numbers are 95 mm diameter with a 63 mm width. This listing is about 89 mm wide. Measure the old impeller width before ordering.

Will this fit every CAT 3304 / Detroit Diesel / Volvo TAMD? +

No. Only pumps whose parts list calls for 17936-0001, 8301-01 or 4L8470. Match the original number rather than an engine family.

Perkins 0460027 is also on the 9-blade listing. Which one do I need? +

Count the vanes on the old impeller. 12 blades use this listing (8301-01). 9 blades use 8200-01 / 6760-0001.

Is this a kit or just the impeller? +

This listing is the impeller only. JMP 8301-01K is a kit number that adds a gasket and O-ring. Photos of this SKU show the impeller on its own.

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 a 12-blade, 95 mm 12-spline impeller, 88.8 mm wide with a 25 mm bore. It will not fit 9-blade 8200-01 of the same envelope, or 63 mm-wide 8100-01 of the same diameter.
  • 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.
