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 17935-0001, and is also supplied against JMP 8100-01, Johnson 09-819B and DJ 003-1201.

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 836-0001 / 8000-01)
3. Drive type (this listing is a 12-spline hub, 25 mm bore)
4. Pump model (cast or labelled on the pump body)

Identify it physically before ordering. This impeller has twelve vanes moulded in black neoprene around a machined brass 12-spline insert. JMP 8100-01 is 95 mm diameter, 63 mm width and 25 mm bore. Jabsco Profile Q. It shares that envelope with 9-blade 8000-01 / 836-0001; count twelve blades before ordering. It is not a double-flat 8001-01.

  • ✓ Primary OEM: Jabsco 17935-0001
  • ✓ Product form: 12-blade neoprene impeller, brass 12-spline insert, 63 mm width, 25 mm bore
  • ✓ Fitment: part number, then blade count, then drive type

Confirm the original impeller number and count twelve blades on a 25 mm 12-spline hub. Do not assume every CAT 3304 / 3306, Volvo TAMD or Cummins NT855M uses this part. Early lower-speed Volvo TMD pumps used the 9-blade 8000-01 of the same size.

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. The product photo is a genuine Jabsco 17935-0001-P kit card. JMP 8100-01K adds cover gaskets (GAK0007 / GAK000701), an O-ring (ORG0015) and lubricant.

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 17935-0001, JMP 8100-01, Johnson 09-819B, DJ 003-1201, CAT 5L6042 / 5N9360 / 1W9046, Northern Lights 25-14802 or Perkins 7054, and the brass hub is a 25 mm 12-spline about 63 mm wide on a 95 mm 12-blade impeller, this part is the correct size.

Is this the same as 836-0001 / 8000-01? +

No. Those numbers are the same outer size with 9 blades. This listing is 12 blades. Count the blades before ordering. Early lower-speed Volvo TMD pumps used the 9-blade part.

Will this fit every CAT 3304 / 3306 or Volvo TAMD? +

No. Only engines whose parts list calls for one of the original numbers in the cross-reference table. Match the original number.

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. The product photo is a genuine Jabsco 17935-0001-P kit card. JMP 8100-01K is a kit number that adds gaskets, an O-ring and lubricant. Kit extras are not included.

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, 63 mm wide with a 25 mm bore. It will not fit 9-blade 8000-01 / 836-0001 or double-flat 8001-01 of the same outer size.
  • 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.
