Hi, I am not sure.
These cans look like they are designed for mounting to the round tube of a tower. I believe a 2004 XStar for instance had some holes in the tube and the bolt that held the cans would actually come in from above through holes in the tube and out the bottom of the tower tube and into the can bracket.
So if your tower does not have those holes, you would need to drill, and u don't want you to drill unless we measure the curve in the can mounts to make sure it would work.
I like these smaller cans on a 197 ZFT or min tower I think they will look right sized but I am really not sure of the fitment.
If you want to send me the diameter of your tower tube, then I can mock up a mount on PVC pipe and send you the pic so we see if it shows any promise.
I want to make sure it would work for you prior to any purchase, after all I bet you have a sweet boat, love the 197tt
Keep a tight line, and a smile on your face. Peace out.
