size of the jet pump impeller 66 the end member 16 is matingly coupled to the impeller 66 of the jet pump 46 the end member 16 is configured to mount about and be in physical contact with the stator vanes 48 both the body 14 and the end member 16 have a circular shape although any shape is contemplated including square polygon rounded and the like however a circular shape is preferred since the water will flow over the jet pump tail cone insert 10 in a preferred embodiment the jet pump tail cone insert 10 can be comprised of three separate parts that are joined together as described above it is contemplated that in other designs more than three separate pieces may be required in order to fulfill the purpose of the jet pump tail cone insert 10 the cap 12 the body 14 and the end member 16 matingly couple to each other the jet pump tail cone insert 10 may not be water tight however the jet pump tail cone insert 10 is designed to fit snuggly to the bearing hub and stator vanes in order to prevent the flow of water between the jet pump tail cone insert 10 and the stator vanes as illustrated in fig2 3 and 4 the body 14 and the end member 16 are.
