Overview

The Jabsco 13554-0001-P is a neoprene flexible impeller for pumps that take a 12 blade Profile K impeller with a 2-1/4 in diameter, 1-29/32 in depth, and a 5/8 in spline drive hub. The hub uses a brass insert, so the main fit points are easy to confirm before you order.

On boats, this impeller size is commonly used in bronze flexible impeller pumps for engine cooling, bilge service, transfer, and other general-purpose water handling. When you are replacing a worn impeller, the most important checks are the profile, blade count, outside diameter, depth, and hub style rather than the pump application alone.

Key features

• 12 blade neoprene impeller in Jabsco Profile K
• 2-1/4 in diameter and 1-29/32 in depth for pumps that need this exact impeller size
• 5/8 in spline drive hub with a brass insert
• Fits marine flexible impeller pumps used for engine cooling, bilge, transfer, and general water service when the pump matches these dimensions
• A practical spare to keep aboard for scheduled service or an unexpected impeller change

Compatibility and fit

This impeller is a good match when your existing pump is built around the same Profile K geometry and spline hub. That matters on older boats and mixed-service systems where the pump tag may be hard to read, because the impeller itself gives you the clearest fit check.

Neoprene is the common choice for water-based marine duties, especially engine cooling. It also suits many bilge and transfer setups that use a flexible impeller pump, but the pump still needs to call for this exact size and hub arrangement.

Installation and maintenance

Remove the end cover and pull the old impeller by the hub. Avoid levering against the pump body with screwdrivers, since damage at the housing face can lead to leaks when the cover goes back on.

A light coat of grease on the new impeller helps during installation and gives it some protection during first prime. This is the kind of service part many owners replace on a routine schedule and keep as a spare on board, especially when the cooling pump is critical to getting home.
