Impeller is sticking.

Hi All,

The flexible impeller in my Jabsco water pump is seizing up. I'm certain it's the correct impeller for the model pump, and it works when I initially put it in. After a few days, it seems it must have swollen and rubs the cover plate to the extent that it will not turn anymore. What gives?

Thanks,

John

did you lube it up?

i just got a new boat and i'm getting ready to replace the impeller. the instructions call for lubing it up with some kind of special lube - i think glycerine.

If the cover plate is scored, you need to replace the cover plate as well as the impeller. Try using a GLOBE impeller as they last longer and can be run dry for up to 15 minutes...I've had real good luck with them. Here's a link & there is a cross reference for Jabsco on the site.
