Jabsco 15299-1000 Priming Impeller Kit
The Jabsco 15299-1000 is the genuine priming impeller kit for Jabsco 15780-0000 and 15780-0100 bronze marine diesel engine cooling pumps, with flanged ports. The priming impeller is the flexible impeller that gives the pump its self-priming ability and moves water at low speed before the main pumping action takes over.
These pumps supply raw water to the engine heat exchanger, so a worn part shows up as rising engine temperature, slow priming or reduced flow at the overboard discharge. Replace worn parts during a planned overhaul rather than waiting for an overheat alarm, and inspect the neighboring parts in the pump end at the same time, since they wear together.

Frequently Asked Questions
Q: What should I inspect while the pump is open?
Check the impeller, cam ring, plate faces, shaft seal and bearings, since they wear together.
Q: How do I know the cooling pump needs attention?
Rising engine temperature, reduced flow at the overboard discharge and slow priming after start are the usual signs.
Q: Should I rebuild the whole pump at once?
On a critical engine it is good practice to replace the wear parts together during a planned overhaul.
Q: Can the pump run dry?
Only briefly at start while it primes. Close the seacock only with the engine stopped.
