Allriiight, you should be able to get the mounting templates of both models on the B&G web site. Go to bandg.com, click on Support, then Downloads, then Manuals
, then select the Zeus model of interest, to get the PDF of the installation
guide. I installed a Zeus2-12 under the aft end of our cockpit
table a year ago and it's worked quite well, other than ceasing to talk N2K due to transmit errors (it's at B&G for repair at the moment). I'm looking at putting a Vulcan 7 at each helm
in lieu of Triton displays and autopilot
controllers, if it fits.
