Recommend trying Great Lakes Boat Top Company, 15 Quality Cir, Vonore, TN 37885. I got full camper canvas and cockpit cover from them for my 2002 322. https://greatlakesboattop.com/ Their make/model selection system lists a 2018 278 SS, but their pulldown for year does not go past 2018. Might give them a call...1-877-867-7861

Chris, late reply, but I just joined. I'm the original owner of a 2002 322 and mine is a TFXIDD by Techsonic Industries (evolved into Hummingbird). Yes, it is a 200kHz

I'm an original owner of a 2002 322 and solved the trumpet horn issue by taking it to the radar arch. Made a custom bracket for it out of aluminum. I used 1/4x1" stock for the mounting survice and vertical rib and the base out of old scrap from a boat trailer wench mount. Then had a welder put them together and painted it white. It worked great! see attached. Two points on mounting. The top of the radar arch is slightly curved. Thought of it as a nonissue... put a base of silicone down and tighten each of the four screws down a little at a time. I also made a point of tightening the front two ahead of the others to pull the horns slightly downward to ensure water would drain out.

Repowering my 322 with 383 Strokers with 350hp . Can anyone advise of what will the the potential change required wrt props. Curent have 24" pitch on Bravo 3s.
