I have heard they have to pay royalties too Malibu for the CATS technology and will be phasing it out. This could be why A LOT of dealers don't order boats with it anymore. Honestly when you compare pennies to pennies its not that expensive option for an actual increase in performance ability/adjustability. I mean, you can get literally change some seating options/trailer options and have CATS.
Also if re-sale is important it seems to me like centurion guys are a niche group of boat owners and CATS has been a important option in the past so I could see why people would value that option in the aftermarket.
I am also a new owner so take everything I say with a grain of salt. But I searched for the answer to that exact question for about two weeks and thats what I took from it. Happy boating!
(P.S. I took a boat with CATS over a boat with the H6 and some other options at the same price after taking some advice on the Facebook group)
