Welcome to the Raymarine Forum Charlie,

As you have suggested, Raymarine neither recommends nor supports installation of CHIRP/DownVision transducers inside of the hull. Due to the relatively low power output of these transducers, hull material can significantly reduce the performance of these transducers. These transducers are also designed to be installed parallel to the vessel's center line with its narrowest width oriented toward the stern. The transducer should be install such that it is level side to side as well as fore to aft with the vessel's waterline. On sailing vessels, fishfinding depth transducers are typically installed forward of the keel to avoid turbulence and other adverse affects from the keel.
