Bilge xducer…I have had really good success using the JB Weld. type epoxy . I would take some laquer thinner or Acetone and clean the area ….make a dam out of plumbers putty or modeling clay fill the area wth JB and place the Xducer in the well.. I usually take an old sock and put gravel , shot , marbles etc in it and place it on the Xducer….you need something that will conform to the odd shape….. this work for me….
