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 keyed shaft. It replaces the primary original part number Jabsco 4568-0001, and is also supplied against Johnson 09-801B, DJ 08-22-1201 and Yanmar 124310-46090.
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. Drive type (this listing is a key-drive hub, not a 12-spline and not a pin drive)
3. Pump model (cast or labelled on the pump body)
4. Engine model code (on the identification plate)
Identify it physically before ordering. This impeller has twelve vanes moulded in black neoprene around a machined brass key-drive insert. Jabsco 4568-0001 is 57 mm diameter, 31.5 mm width and 16 mm (5/8 in.) bore, Profile K. It is not interchangeable with the 12-spline Jabsco 1210-0001 (same outer size, different hub) or with the thinner 12-blade key-drive JMP 7110-01 (57 × 20 × 12.7 mm).

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.
The supplied photograph is a genuine Jabsco 4568-0001-P retail kit. Cover plate gaskets and lubricant from that kit are not included with this listing. If your service procedure calls for a new cover seal, order it separately against your pump model.
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 key 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 keyway in the brass insert with the pump shaft key, 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 key-drive, 16 mm bore impeller. It will not fit the 12-spline 1210-0001 or the thinner 12.7 mm key-drive JMP 7110-01.
- 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.
