Transducer removal, I love hate 3M 5200 (video)

Removing an old depthsounder transducer from a 1990 Hunter 335.  5200 is great, until you need to remove it!!!  Replacing it with a Raymarine Dragonfly bronze transducer.  The old one was a 1990s Singnent somthing or other that didn’t work when we bought/rescued the boat.
