I am selling my 2018 Centurion RI237. It was Centurions Demo boat for their 2018 video you can watch it here - https://www.youtube.com/watch?v=bXjZmt7FrwU The boat currently has 387 hours. The boat is on a tripple axle trailer, I replaced the tires 2 years ago, all the hubs were replaced 2 years ago as well. The interior boat I changed the downfire system to Wetsound Rev 10 - The amps inside are a exile audio that controls interior speakers and subwoofer, I did change out the factory sub for a exile audio sub. It bumps. The Wetsound amp powers the tower speakers. Just had it serviced at Lynnwood motoplex. I have 1,000 lbs of lead in it. Makes it nice so if you only have 2 or 3 friends out on it you can get a massive wake with still filling up the ballast 70%. This thing has been awesome and throws an incredible wave. The swimstep has a latter, and I changed out the radio unit from factory. I got a new cover for it last year.
