Jabsco 673-0001-P Flexible Neoprene Impeller Service Kit

The Jabsco 673-0001-P neoprene impeller kit provides a six-blade replacement for compatible marine water pumps with a nominal half-inch pin-drive shaft. Its 51 mm outside diameter, 22 mm depth and brass hub make it a compact service part, but the 12.7 mm shaft fitting remains essential to correct selection.

Choosing the Correct Replacement

Jabsco lists this impeller for drive types 1 or 2, corresponding to slotted shaft and through-hole pin arrangements. Compare the actual pin engagement with the pump shaft. The selection guide also notes the newer 18673 series as a possible replacement; confirm the applicable pump recommendation before changing series.

Similar Impellers: What to Check

The 653-0001 has the same nominal outside dimensions and six blades but uses a 12 mm shaft fitting. The 22799-0001 has a 12.7 mm bore but uses a key drive. The ten-blade 18653-0001 is also a different 12 mm fitting, despite its similar appearance.

OEM References & Cross-References

Jabsco lists the following reference numbers for this impeller family:

• CEF: 500116
• Johnson: 09-1026B
• Volvo Penta: 804696, 875808, 897055

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 6-blade configuration and slotted shaft / through-hole pin drive (jabsco types 1 or 2) 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.
