23.5 Depth
I too have a 94 23.5. I bought a Raytheon 265 fishfinder and mounted the transom transducer inside the hull behind the ballast tank using RTV silicone. Didn't work. I called Raytheon and they said that "unofficially" you could use the transom transducer inside the hull, but it has to be mounted in epoxy. I ruined the transducer cable trying to remove it (entirely my fault) and am waiting for a puck tranducer that is presently backordered. This is a really a cool little unit, its under 200 dollars and appears well made...if I could just get it working..Fair WindsAlan LongS/V Random Access
