Call the factory, 870-481-5135 mon-fri. See if they have any “pop axle” bolt ons left. Served the same purpose as Go Jacks, but mounted on the trailer frame and had a slide bar that would keep the front axle slightly elevated for maneuvering. Should fit on an 07, if they still have them.And congrats on the boat!96 Eyra/12 Mercury 175 Pro XS with 2015 single axle trailer2017 Victory Gunner
