(Help) Raymarine Dragonfly -Hobie outback

[Fish Taco]

Well this thread is disheartening... I am having Andy help out with my install today on my Stealth with an over-the-side transducer. On my move out from New York the movers lost (or ripped off) my head unit to my older Elite 5 (2011) which I still cannot find. Decided to upgrade to a Dragonfly 7 Pro. My original 'ducer was mounted to the inside of my hull by CJ in 2011. Was really hoping that this was going to be a smooth upgrade, but after reading this thread, not so sure. Guess I'll just have to cross my fingers and wait and see... ugh...
