The Jabsco 18948-0001-24 is a bulk carton of 24 genuine Jabsco 18948-0001 neoprene impeller kits, packed for marine service shops, fleet operators, boatyards and parts counters that replace raw water impellers on a regular schedule. Each impeller is the same 12-blade, key-drive design used in the single-pack 18948-0001 kit, with a 2-9/16 inch diameter, a 1-5/8 inch width and a brass insert bored for a 5/8 inch keyed shaft.
Neoprene is the standard compound for engine cooling and fresh or salt water transfer, and it is the right choice for most raw water pumps on inboard engines and generators. Buying the carton keeps a consistent, known-good impeller on the shelf so every haul-out, winterization or cooling service call can be finished without waiting on parts, and every boat in your care gets the same quality replacement.

Frequently Asked Questions
Q: How often should a raw water impeller be replaced?
Most owners replace the impeller every season or roughly every 300 to 500 engine hours, and sooner if the boat sits for long periods or the pump has run dry.
Q: Can a neoprene impeller handle diesel or oily bilge water?
No. Oil and fuel attack neoprene and cause the blades to swell and fail. Use a nitrile impeller where the pump will see oily liquids.
Q: Is this carton the same impeller as the single 18948-0001-P kit?
Yes. The impeller design is the same; only the packaging and quantity differ.
Q: What should I check when changing the impeller?
Inspect the wear plate and cam for scoring, replace the cover gasket or O-ring, and make sure no broken blade pieces are left in the cooling system.
