put a new hummingbird gps/fish finder in my boat. when i hit rough water it keeps cutting off. has anyone had this problem? would it be in the wiring or the bracket where it slides into the plugs? any help would be greatly appreciated.
Most likely a wiring connection that you made. The plug on the back of the unit should have a a threaded lock. I had the same problem when I first installed my GPS as well.

Check the fuse,if it has an inline glass fuse they loose their connection when the boat pounds in rough water.
