Thanks to both of you!
I figured the jet was only 1/2 a jet with the other 1/2 stuck inside the body. I contacted Waterway with the 1st and 3rd photos and they gave me a part number of their jet. I went online to a spa parts dealer and they are telling me that this is not a Waterway jet so I emailed Artesian about what jets they used. I have never had these particular jets out and realized when I took it out that the jet had no way of controlling the amount of water coming from them and the skinny part looked as though they snapped off. I was surprised that all 4 jets snapped the same way but the tub is older and I hadn't taken care of it as I used to ... so the plastic probably got brittle.
I have a bunch of new, larger jets that I have had since the tub was new as some of my jets started falling out because the tabs broke off and Artesian sent me a lot of replacement jets but no smaller jets. I know to rotate one way to remove (left) and increase flow and the other way to lock in and reduce flow.
Once I drain the tub I will attempt to remove the parts in the body, I will try the can opener and if that doesn't work they I'll do plan B whatever that may be!
Actually I was thinking of screw removal items but I have to rethink that.
Thanks again and if you have any other ideas - please share them!
