The Jabsco 22405-0001-B is a genuine Jabsco 22405-0001 neoprene impeller kit in plain bulk packaging. This 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, and it is widely used in small raw water cooling pumps on marine diesel engines and generators.
Small engines depend on a healthy impeller just as much as big ones, and a worn or cracked impeller is a leading cause of overheating alarms. The bulk pack is the same genuine impeller as the retail kit, making it a smart choice for owners who like to keep spares aboard and for shops that service many small diesels.

Frequently Asked Questions
Q: What is the difference between the -B and -P versions?
Both contain the same Jabsco 22405-0001 impeller. The -B is plain bulk packaging and the -P is a retail pack that includes a cover gasket or O-ring and screw.
Q: Can I install the impeller without removing the pump from the engine?
On many small engines, yes. Removing the end cover gives access to the impeller, though tight engine rooms may make it easier to remove the pump.
Q: How do I keep the impeller from taking a set during layup?
Some owners remove the impeller for winter storage or loosen the cover so the blades are not held bent for months.
Q: Can this impeller handle antifreeze during winterizing?
Yes. Neoprene is suitable for water and glycol mixes used in winterizing.
