    Jet pump oring locations

    Hello, Iím currently in the middle of rebuilding a jet pump. I got a kit from sbt that has five gaskets, two bearings, and two seals. I cannot for the life of me figure out where all these orings go. I know of the two on the impeller shaft, one on the tail cone, and Iím guessing they include one for the water pipe. I tried installing the two orings that go on the impeller shaft, but they appear a lot larger than the originals. This is for a 780 slt. I have been to the Polaris database that shows all the links to frequently asked questions, but it didnít really help. Can anyone show me please, or point me in the correct direction? This is not the kit I purchased, but it includes the pictured orings.

    To see what was used by Polaris.
    Why there are that many orings, you would need to ask the people that sold it and that probably will not be helpfull.

    You can find all of the service manuals and parts diagrams here

    I am not that familiar with the older SLT's.

    Yeah I’ve already tried to reach out to them to no avail. I would look at the old locations, however whoever serviced it before me should have replaced the impeller shaft, because the rear bearing race welded itself to the shaft. They did not, and only replaced it with ONE BEARING. Hit a wave and my jet pump ate itself. Hard to tell where things are supposed to go.
