I recently repowered with a 2017 225 SHO and am contemplating adding the interface cable. I have viewed videos and read numerous threads. I realize I need to purchase the interface cable and a nema 2000 starter kit to complete the basic install. I am trying to figure out what engine diagnostics will be displayed on my Lowrance HDS 12 Carbon with this basic setup? What might I want to add to the network that is not included? I have a 2005 Skeeter ZX 225 with analog gauges.
