Overview

The Jabsco 22405-0001-P is a packaged neoprene impeller kit for flexible impeller pumps that use a slotted shaft pin drive and a 6-blade profile. The impeller measures 1-9/16" in outside diameter, 3/4" in depth, and 15/32" at the shaft fit, with a brass insert at the hub.

On board, this size is commonly used in bronze flexible impeller pumps for engine cooling and in some bilge, transfer, and general-purpose pump setups. For older boats, repowers, and pumps that may have been changed over time, the important check is the impeller you remove: blade count, drive style, outside diameter, depth, and hub dimensions all need to match.

Key features

• 6-blade neoprene impeller for pumps that use a slotted shaft pin drive
• 1-9/16" outside diameter, 3/4" depth, and 15/32" shaft fit for checking pump compatibility before ordering
• Brass hub insert
• Profile D, size 010 configuration
• Used in a range of bronze flexible impeller pump applications, including engine cooling and certain service-pump duties where this exact profile and size are specified

Compatibility and fit

This kit corresponds to the 22405-0001 impeller geometry used in several Jabsco size 010 cooling-pump applications. The safest way to confirm fit is to compare the old impeller against the pump requirements rather than relying on engine brand alone.

It is a sensible spare for boats that depend on a compact raw-water or service pump away from the dock. Owners maintaining older diesel installations, auxiliary cooling circuits, or small transfer pumps will usually want the replacement on board before the old impeller starts shedding vanes.

Installation and service

Impeller replacement is straightforward when the pump cover is accessible. Pull the old impeller by the hub, avoid levering against the pump body with screwdrivers, and grease the new impeller before start-up so the pump is not running dry during the first prime.

Flexible impellers are maintenance items, not fit-and-forget parts. On boats that see regular engine hours, silty water, or long layups between runs, changing the impeller on a service schedule is usually cheaper than dealing with a sudden loss of cooling water flow.
