Are you listening for the pings in or out of water? They will have erratic ping rates out of water. Put the transducer in a bucket of water and you can still hear the pinging but it should be a steady and consistent pinging depending on settings. So I wouldn't base anything on how a transducer pings out of water

[Wayne P.]

The head unit sends a pulse to the transducer (speaker function) to broadcast a sound and it waits until it detects a return echo (microphone function) to calculate the time to translate that to distance. If a return echo is not detected within a certain amount of time, it sends another pulse to the transducer.
For a shoot-thru application, the bond between the transducer face and hull has to be solid so both vibrate at the same rate for broadcasting the sound and detecting the return echo. If the transducer is not faulty, the bonding is not faulty, and the hull itself is solid and thin you should get a depth readout.
The only way to properly install a shoot-thru is test on the water with water in the hull so water does the bond between the transducer face and hull (water doesn't compress). You do test runs at all speeds and change the location of the transducer until the best location is determined by actual depth/2D performance. Doing the proper testing will show where and if it will work when bonded properly with epoxy. Anything less than that is a crap shoot if it will work properly.
