Jabsco 17937-0001B Flexible Neoprene Impeller (Bulk / Single Part)

The Jabsco 17937-0001B is a replacement neoprene impeller for compatible marine raw water cooling and water transfer pumps. Its ten flexible blades, brass hub and splined drive identify the familiar 17937 configuration, supplied here as an individual bulk impeller for servicing installations where the remaining service materials are sourced separately.

Choosing the Correct Replacement

The B suffix identifies the individual impeller format. Choose this version when you need the impeller itself, or the 17937-0001-P packaged kit when you require the corresponding service pack. Gaskets, lubricant and additional service accessories are not included with this bulk version.

Similar Impellers: What to Check

The 17937 has ten blades. The eight-blade 920 family shares its nominal 65 mm diameter, 51 mm depth and 16 mm splined shaft size. Where a pump document lists an alternative or superseding impeller, follow that specific recommendation rather than assuming every matching-size impeller is interchangeable.

OEM References & Cross-References

Jabsco lists the following reference numbers for this impeller family:

• Caterpillar: 7C3286
• Perkins: 0460024, 24880031
• Volvo Penta: 801277, 825941, 877061-2
• Yanmar: 127610-42200
• Vetus: IMP00301

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.

Supply Format

Supplied as one individual bulk impeller. Order the correct end-cover gasket or seal and suitable installation lubricant separately.

Why Choose This Impeller?

• Correct replacement specification: The 10-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.
