pump locking up

[oldfooter]

The pump on a friends 96 spx will lock up when turned. If turned backward will turn without locking up. I am going to disasy. what should I be looking for as I have never had a pump apart.

the most common problem with the older pumps is that corrosion gets between the wear ring and pump housing, this cause the wear ring to collapse a bit and lock the impeller
sometimes the rubber coating on the wear ring comes apart and jams the prop
you could also have a impeller shaft bearing failure too.
pulling the pump is pretty easy, a little prying to get the pump free.
dont forget to disconnect the three hoses on the inside on ski
you will need a impeller wrench/socket and a vise to get the impeller off
just take her apart and take note of how it comes apart and inspect all components
good luck

I would also check the impeller for any damage but also check the ware rig the reason i say impeller is if you sucked somthing up there it mave have caused an uneven spot in the prop!
