It came off a JE that I bought for other parts.
The long plate attaches to the bottom rear of the suction housing, and the other piece attaches to the plate via rods/hyme joints and bolts to the bowl. It came to me disassembled, and I don't really know any more than that. I've only had 1 jet boat, so I am not familiar with this type of piece at all.
I'd be happy with maybe $75?
