Jabsco 4568-0001-P Profile K Neoprene Impeller Kit

Jabsco Profile K Neoprene Impeller Kit – 4568-0001-P / 6-45680001P

Product Description

The Jabsco 4568-0001-P is a 12-blade neoprene flexible impeller kit for compatible marine engine-cooling, bilge, transfer and general-purpose bronze pumps. It uses a durable bronze hub with a keyed drive and is designed primarily for circulating fresh water or salt water where only minor oil or diesel contamination may be present. The packaged kit includes the impeller, sealing gasket components and installation lubricant.

• Jabsco 4900-series pumps
• Jabsco 21770-series pumps
• Johnson Pump 09-801B – F5B applications requiring the equivalent impeller
• Johnson Pump 10-32058-1
• Johnson Pump 10-32621-1

Always confirm the complete pump model, shaft diameter and keyed-drive configuration before ordering.

Engine Compatibility

Documented Volvo Penta applications include:

• 230A and 230B
• 250A and 250B
• 251A
• AQ120B
• AQ125A and AQ125B
• AQ131A, AQ131B, AQ131C and AQ131D
• AQ145A and AQ145B
• AQ151A, AQ151B and AQ151C
• AQ165A
• AQ170A, AQ170B and AQ170C
• AQ171A and AQ171C
• AQD21A and AQD21B
• BB140A
• BB145A
• BB165A
• BB170A, BB170B and BB170C
• MD21A
• MD21B from the applicable later production range

The impeller also cross-references Yanmar 124310-46090. Engine model alone should not replace confirmation through the installed pump number or engine cooling-system diagram.

Fitment Notice

Before ordering, confirm that the original impeller requires:

• Twelve blades
• 2-1/4-inch outside diameter
• 1-1/4-inch width
• 5/8-inch keyed shaft
• Bronze hub
• Profile K
• Neoprene construction

Do not confuse this impeller with the dimensionally equivalent 4568-0003-P. The 4568-0001-P uses neoprene for water and engine-cooling applications, while the 4568-0003-P uses nitrile for liquids with greater oil or diesel exposure.

When This Part Needs Replacement

Replace the impeller when:

• Raw-water or transfer-pump output decreases
• Engine temperature begins rising
• Exhaust-water discharge becomes weak
• The pump struggles to prime
• Vanes become cracked, hardened or permanently curved
• Blade tips are worn or missing
• The bronze hub becomes loose
• The pump has operated dry
• Preventive annual service is due

Flexible impellers should generally be inspected regularly and replaced preventively, particularly in engine-cooling systems where failure can quickly lead to overheating.

Installation Notes

• Shut down the engine and isolate its starting system.
• Close the raw-water seacock or applicable isolation valve.
• Remove the pump cover and old gasket.
• Withdraw the old impeller with a suitable puller or by carefully gripping the hub.
• Recover all missing blade fragments from downstream hoses, heat exchangers and oil coolers.
• Inspect the cover plate, cam, pump bore, shaft and key for wear.
• Coat the replacement impeller with the supplied lubricant.
• Align the hub keyway carefully with the pump-shaft key.
• Install the supplied gasket and refit the cover.
• Open the seacock and verify strong water flow immediately after startup.

Never run a flexible impeller pump dry for more than the brief period required to establish prime.

Parts Desk Insight – Best Use

The 4568-0001-P is the go-to service impeller for Volvo Penta AQ/BB/MD-series raw-water cooling pumps and Jabsco 4560/4900/21770-series bronze pumps. The keyed bronze hub and 12-blade Profile K geometry are distinctive — do not substitute a plastic-hub or single-flat impeller even if the outer diameter appears similar. Neoprene is appropriate for clean raw-water and engine-cooling circuits; if the pump is exposed to oil or diesel contamination, the nitrile 4568-0003-P is the correct compound. The Johnson Pump 09-801B is the direct OEM-equivalent for F5B pump applications. Always recover any broken blade fragments from heat exchangers and oil coolers before restarting the engine — fragment ingestion is the leading cause of secondary damage after impeller failure.
