This impeller fits many applications, among them the coolant pump (Jabsco 5850) of my boat engine. The engine was overheating; the impeller was ripped and had pieces missing. Replacement of the original impeller with this one did not immediately fix the overheating--I had failed to remove the detached pieces of neoprene torn off the original impeller. Once I dug through the coolant tubes to remove the blockage caused by the errant pieces of vane, the engine temperature returned to normal, the pump worked perfectly.

With any "rubber" impeller, whether a genuine Jabsco or an aftermarket substitute, don't turn the pump backwards; and don't operate the pump with a restriction on the water outlet. Medium- and long-term storage requires that the impeller be removed or it will take a "set" and several vanes will no longer function properly.

Impeller life can be extended--sometimes--by reversing the impeller in the pump if there's no damage other than the vanes are curved and worn at the tips.

If you replace your own impellers, a puller tool is WAY recommended. I have the Jabsco 50070-0080 compact puller.
