Choosing the Correct Replacement

Select this impeller where the pump manufacturer specifies Jabsco 836-0001 or confirms a corresponding original equipment reference. The -0001 identifies the neoprene version for water duties. Other 836 material variants should be selected only against the pump and fluid specification.

Similar Impellers: What to Check

The 17935-0001 has twelve blades, despite sharing the nominal 95 mm diameter, 63.5 mm depth and splined shaft size. The 6760 family is deeper at 88.9 mm. Blade configuration and depth should both be checked before deciding that another impeller is suitable.

OEM References & Cross-References

Jabsco lists the following reference numbers for this impeller family:

• Caterpillar: 1L4774
• Cummins: 160596, 166758, 556540, 556850
• Johnson: 09-1029B
• Vetus: IMP00901
• Volvo Penta: 807904, 825942, 875660, 875736, 876602, 21430184

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 9-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.
