Jabsco 920-0001-P Flexible Neoprene Impeller Service Kit

The Jabsco 920-0001-P neoprene impeller kit provides an eight-blade replacement for compatible marine water pumps. With a 65 mm outside diameter, 51 mm depth and brass splined hub, it is intended for installations that specify the 920-0001 water-service impeller.

Technical Data & Parameters

Choosing the Correct Replacement

Confirm the pump part number before choosing an eight-blade replacement. Neoprene is used for fresh and salt water duties; the similarly numbered 920-0003 is a nitrile version intended for different fluid requirements. Match the specified material as well as the size.

Similar Impellers: What to Check

The ten-blade 17937-0001 shares these nominal dimensions and appears as a replacement in some Jabsco pump documentation. Use a manufacturer-approved replacement for the specific pump model. The 17018 family is deeper at 76.2 mm and should not be chosen simply because its diameter and spline size match.

OEM References & Cross-References

Jabsco lists the following reference numbers for this impeller family:

• Cummins: 650607
• Johnson: 09-1028B
• Volvo Penta: 801277, 825941, 877061-2, 875593

Use these numbers to identify the original impeller, then confirm the pump model and current replacement specification. An engine brand alone does not establish compatibility.

Service Kit Selection

This listing is the packaged -P impeller version. Match any supplied gasket or seal to the fitted pump and use only the correct end-cover sealing arrangement. An impeller service pack is not a complete pump overhaul kit: inspect the shaft, cam, cover and seals separately, and order additional worn parts as required.

Why Choose This Impeller?

• Correct replacement specification: The 8-blade configuration and spline drive help identify the required service part.
• Neoprene for water duties: Suitable for fresh and salt water applications where approved for the pump.
• Serviceable component: Replacing the impeller allows a compatible pump to be maintained without automatically replacing the complete assembly.

Installation & Maintenance

Follow the fitted pump's service instructions. Isolate its drive and close the relevant seacock before opening it. Remove the old impeller with a suitable tool, inspect the chamber for wear and recover any missing blade fragments. Fit the correct cover gasket or seal and lubricate the replacement with an installation lubricant approved for the pump and neoprene.

Restore the water supply before starting, then check for leaks and normal water delivery. Avoid dry running. Include the impeller in routine servicing and keep a matching spare available for essential onboard systems.
