I figured this out. I have an 'on hull' transducer (as opposed to a thru hull). In the little housing that it sits in, has to have a liquid. I think the recommend water system anti-freeze (pink stuff, cant remember the chemical name). anyway this has to have liquid in there, if for some reason it leaked out, or if it evaporated, whatever you have to refill. Just twist the top off, pour some in , replace the top, and you should be good to go. it happened to me this year as well, and this is what I did to repair!! Just FYI!!
