At present my boat has the depth transducer mounted about mid-keel, on the starboard side of the keel (boat came with no instrument, just depth and speed transducers mounted in bad locations), I want to get a fishfinder, and use a puck transducer to shoot through the hull; question is: I want to put the transducer forward of the keel, but am unsure of exactly how to do this. The location looks like it'd be under the liner just inside the v-berth - can I cut a hole in the floor for the transducer? what will I find in this location?
