I had a 2009 CougarFTD. I traded it for my 2015 Caracal. While I’ve not measured anything, it fits exactly, into the same space that my Cougar was in. The trailer is the same width I am certain. (Approx 102″) The length of the rig on the trailer is a bit shorter, but again, I have no measurements. The only place I see a difference is at the front half of the boat. I’d guess a bit more of the boat is out over the trailer than the Cougar. That makes no difference though, as the rear of the trailer is the same width. The boat doesn’t hang out beyond the trailer at the rear. In other words if a Puma or Cougar fit into your garage, the Caracal will too. I can’t speak to engine height, but I’d guess its the same. I don’t know about the new 4S ProXs.
