Interesting? stuff from Airmar.

The transducer that is "weeping" appears to be a solid mass with an outer face made of different material than the casing that mounts it in the hull. The plastic casing, perhaps Nylon, must be allowing tiny amounts of water to seep between the internal mass and its inner wall. That moisture is working its way up the transducer and appearing on the inner surface of what does look like a poured filling of ? epoxy. I can't see where the moisture is "arriving". The inner surface of the poured top of the transducer is shiny and looks, in the poor light, to be unbroken.

Since I am replacing it and it is junk I may cut it up for closer inspection. That will be a few weeks away since Tundra is still on its mooring in Seal Harbor. Perhaps I can get Mainesail to have a look at it.
