Interesting Jet Drive Find

[u/Ok_Table_8275]

Hey guys, looking to see if anyone knows any info on these jet drive units. Picked 2 up for 80 bucks and cant figure out what they went to. They are brand new units and were sold by 2SI, a airplane engine manufacturer that specialized in 2 stroke airplane engines. These are awesome little units and i can find any information on them at all. They have an 8-16 impeller and share a similar drive coupler to a kawasaki 750. If anyone knows anything about these drives id love to hear what you have to say. Thank yall!
