My neighbor runs 5" Lowrance HDI on his 18' CC. It is feature packed and gets the job done. 7 would be nice but at the same time its nice not having huge screen in the way.

Install is rather simple. The transducer cable should run down a conduit through the hull to the back along with other wiring like ignition/throttle/trim. The transducer plug end is large and can be a biatch. You can "pull" the cable through conduit with any home improvement store electrical pull tape reel. Power is simple because you do not need to hook up the communications wires. Power is 3 wires IIRC, hot, neutral, ground
