I am very close to pulling the trigger on purchasing a 9″ Helix to install in my Pantera II (I am in the store right now). I still have the original 5″ Hummingbird 787c at the console. I get really nervous about cutting holes in my boat. Does anyone have any pics that I can take a look at to see how it would look? Will I have enough room on my dash? I have not made any measurements yet to see. Help!!!!!!!!!!!!!!!!!!!!!!
