Default B175H electrolysis or corrosion? Pictures included

Hey guys. I installed thisb175h last year, applied some transducer anti fouling paint, and it's been working great for a year. Well I hauled my boat out one year later and was pleasantly surprised that my bottom was extremely clean. I did notice that the transducer face seems to have a small green lip where the face of the transducer meets the bronze housing. I haven't noticed any difference in transducer performance. Any thoughts on what this is and if I should do something about it?

Anti fouling paint will be good for barnacle and marine growth but it normally is not a full deterrent for corrosion.
All it takes is a pin hole.

And thats a great looking boat!

Thanks for the quick reply, Gil. I'll reapply the paint. My only concern was the little lip that had been created but I guess it shouldn't be a concern. Thank you for the input and giving me some peace of mind.

This transducer shows the 'acoustic window' has delaminated from the face of the ceramic element. It is an actual circle and includes the thermister, but corrosion has caused one side to push out.
Because it is a mechanical item, it moves in sympathy to sonar pulses. Transducers do wear out and this is a classic example.
It will work in this condition until water ingress corrodes the wires connected to the actual element.
You find your gain requirement to change indicating immanent failure.
