Jabsco 17370-0001-P Flexible Neoprene Impeller Service Kit

The Jabsco 17370-0001-P neoprene impeller kit is a large twelve-blade replacement with a plastic double-flat drive insert. Its 95 mm outside diameter, 88.9 mm depth and nominal one-inch shaft fitting are intended for pumps specifying this particular configuration.

Choosing the Correct Replacement

Identify the double-flat connection before selecting this impeller. The shaft and hub must engage across the matching flats; a similarly sized splined impeller is a different fitting. Use the full pump model and original impeller reference to confirm compatibility for the application.

Similar Impellers: What to Check

The 17936-0001 has the same nominal diameter, depth and twelve-blade layout, but uses a brass splined hub. The 17935-0001 is shallower at 63.5 mm and also uses a brass spline fitting. This model's plastic double-flat insert is therefore a key identification feature.

OEM References & Cross-References

Jabsco lists the following reference numbers for this impeller family:

• Caterpillar: 3N1888, 3N4859
• Cummins: 217308, 3008503
• Detroit Diesel: 8927571

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 12-blade configuration and double-flat drive (jabsco type 5) 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.
