The Jabsco 22405-0001-P is the retail-packed genuine Jabsco 22405-0001 neoprene impeller kit, supplied with a cover gasket or O-ring and screw so the pump can be resealed as part of the job. The compact 6-blade impeller measures 1-9/16 inches (40 mm) in diameter and 3/4 inch (19 mm) wide, with a brass insert for a 12 mm shaft.
This impeller is a common fit in small raw water cooling pumps on marine diesel engines and generators, where a failed impeller quickly leads to an overheating shutdown. Keeping a complete kit aboard means an impeller change can be done at the dock or on the mooring with everything needed to seal the pump properly.

Frequently Asked Questions
Q: Why does the kit include a gasket or O-ring?
The cover seal should be replaced every time the pump is opened. Reusing a compressed seal can let air in and stop the pump from priming.
Q: How long does an impeller change take?
On an accessible pump, often 15 to 30 minutes. Allow extra time if the pump must be removed from the engine to reach the cover.
Q: What if the old impeller is hard to remove?
An impeller puller or two screwdrivers used gently on opposite sides will work. Avoid scratching the pump body or wear plate.
Q: How should I prime the pump after the change?
Open the seacock and start the engine. Check the exhaust for water flow within about 30 seconds, and shut down if none appears.
