Location: Mauston, Wisconsin | Whoa!!! What do you mean by: "because I am mounting it flush to the interior of boat". Just do a search here on MF for "GPS Puck Mounting". The Puck is the antenna, it needs to mounted where it has a free view of the "sky". I'd call Humminbird & ask them for recommendations based on your specific boat model before I drilled hole #1........
