Jabsco Profile K Impeller Kit, For 11810 Series, 12 Blade, Nitrile

Overview

The Jabsco 5929-0003-P is a 12-blade nitrile replacement impeller for bronze flexible impeller pumps used in engine cooling, bilge, transfer, and other general-purpose pumping jobs on board. It uses a Ding Drive keyway hub with a brass insert, and its key fit dimensions are 2-1/4 in outside diameter and 1-1/4 in depth.

This is the kind of service part that needs to match the pump exactly, not just the boat or engine brand. For a correct fit, check the old impeller or pump service data for the same blade count, outside diameter, depth, and Ding Drive keyway hub style before installation. Nitrile is commonly used where the pump may see bilge or transfer duty rather than clean water alone.

Key features

• 12-blade flexible impeller in Jabsco Profile K size
• Nitrile compound for engine cooling, bilge, transfer, and general-purpose pump service
• 2-1/4 in outside diameter and 1-1/4 in depth for fit verification
• Ding Drive keyway hub with a brass insert
• Replacement part should be matched by impeller dimensions and drive style, not by vessel make alone

Compatibility and fit

This impeller is a good match when the pump requires the Profile K geometry and the Ding Drive keyway hub used on this part. On older boats especially, pumps may have been changed at some point, so measuring the removed impeller is often the safest way to confirm fit. Diameter, depth, hub style, and blade count are the details that matter most.

Installation and setup

Before fitting a new impeller, grease the vanes and the pump bore so the impeller is protected during the first prime and slides into place without tearing an edge. Remove the end cover and pull the old impeller by the hub with an impeller puller or pliers. Avoid prying with screwdrivers, because damage to the pump body or cover face can lead to leaks.

This part makes sense for owners and technicians keeping raw-water cooling, bilge, or transfer pumps in service with planned maintenance instead of waiting for a no-flow failure. Keeping a spare impeller on board is common practice on cruising boats, fishing boats, and workboats where pump downtime quickly becomes a bigger problem.
