Raytheon L365 depth-o-meter advice
Have an old boat with a nonfunctional Raytheon L365 depth finder. Its transducer/probe thingy is embedded in a through-hull in the bottom of the hull. My question is: are these probes interchangeable? is there any chance that if I buy a new Raytheon or other depth-o-meter can I just plug it in to the existing probe... or do I have to rip it out of the hull and replace it - hopefully in the same through hull....
