Engine Compatibility
Supported cross-reference applications include compatible raw-water pumps used on selected:
- Caterpillar marine engines
- Detroit Diesel marine engines
- MAN marine diesel engines
- Perkins marine engines
- Volvo Penta marine engines
- Yanmar marine engines
- Johnson Pump installations
Frequently documented OEM references include Caterpillar 4L8470, Detroit Diesel 5196168, 5198550 and 8924839, Perkins 460027, Volvo Penta 875814-6 and Yanmar 165000-35270. Fitment must be confirmed through the installed pump or original impeller number rather than engine make alone.
Fitment Notice
Before ordering, confirm that the original impeller requires:
- Twelve blades
- 3-3/4-inch outside diameter
- 3-1/2-inch width
- 1-inch spline-drive shaft
- Brass hub insert
- Profile Q configuration
- Neoprene construction
- Jabsco 17936-0001 or 17936-0001-P specification
This is a substantially larger impeller than the 65 mm Profile Y models such as the Jabsco 17937-0001-P Profile Y Neoprene Impeller Kit. Confirm all three dimensions and the spline-drive configuration before ordering.
When This Part Needs Replacement
Replace the impeller when:
- Raw-water or exhaust-water discharge decreases
- Engine operating temperature begins rising
- The pump becomes difficult to prime
- The blades become cracked, hardened or permanently folded
- Blade tips are torn or missing
- The brass spline hub becomes loose or damaged
- The pump has operated without adequate water
- Scheduled annual cooling-system service is due
Jabsco service guidance recommends replacing flexible impellers at least annually, or sooner where engine duty and operating conditions are severe.
Installation Notes
- Stop the engine and isolate the starting circuit.
- Close the raw-water intake seacock.
- Remove the pump end cover and old sealing components.
- Use a proper impeller-removal tool or suitable pliers to grip the hub.
- Do not pry against the pump housing with a screwdriver.
- Retrieve any missing blade fragments from hoses, coolers and heat exchangers.
- Inspect the pump bore, cam, shaft, splines and cover plate for wear.
- Lubricate the replacement impeller before installation.
- Align the brass spline hub carefully with the pump shaft.
- Install the supplied spline seal and cover gasket.
- Reopen the seacock and verify strong water flow immediately after startup.
For MAN applications, verify the separate engine-specific sealing O-ring; references associate MAN 51.96501-0580 with this installation, and it may not be included with the impeller kit.

Parts Desk Insight
This is one of Jabsco's largest standard flexible impellers. The critical identifiers are its 3-3/4-inch diameter, 3-1/2-inch width and 1-inch spline hub. Because it is used across several heavy-duty diesel engine brands, the installed pump number or original impeller reference provides the safest fitment confirmation. Also available under the Jabsco Neoprene Impeller Kit 17936-0001-P – Flexible Raw Water Pump Service Kit listing.
