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 17938-0001, and is also supplied against JMP 8326-01 and DJ 09-45-1201.
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 8250-01 of the same envelope)
3. Drive type (this listing is a 12-spline hub, 25 mm bore)
4. Width (this listing is 95 mm wide, not the 88.8 mm 8301-01 of the same diameter)
Identify it physically before ordering. This impeller has twelve vanes moulded in black neoprene around a machined brass 12-spline insert. JMP 8326-01 is 95 mm diameter, 95 mm width and 25 mm bore. It is not interchangeable with 9-blade 8250-01 of the same envelope, or with 88.8 mm-wide 8301-01 of the same diameter.
- ✓ Primary OEM: Jabsco 17938-0001
- ✓ Product form: 12-blade neoprene impeller, brass 12-spline insert, 95 mm width, 25 mm bore

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 8326-01K is a kit number; kit extras are not included.
Installation Guide
- 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 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 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 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 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 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
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, 95 mm wide with a 25 mm bore. It will not fit 9-blade 8250-01 of the same envelope, or 88.8 mm-wide 8301-01 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.
