I have a st60 depth finder with a weak transducer on the bridge of my trawler it quits when I need it the most should i just replace the transducer or can I link via seatalk to the L760 in the cabin what are the + and -

Look for a bad connection or corroded contacts, a transducer is normally good or bad, not weak. Blue is tranducer +ve and Black is transducer -ve, for the seatalk, red is 12vdc +ve, black is 12vdc and data -ve, yellow is data +ve.
