Those look like they were designed for a stern drive or OB, the control may of may not have the correct throw for the reverse gate on the jet. I'm sure it could be made to work but may require some modification for proper adjustment. Also make sure it is for the proper side of the boat, i.e. left hand or right hand side.
Livorsi makes a similar one that will work on a jet also Livorsi Marine, Inc. - Side Mount Controls, any of these are pricey however, but they sure are nice looking.I don't know if these would work for a jet. I saw them in the Overtons catalogue last year. They were 329.00. In the new catalogue they're $100.00 more! I was gonna put one on my boat this week till I saw the price increase. <br>Eddie Marine has a billet one that might work for your jet.
