There is likely a way.
What model # is the transducer?
You can go to airman.com/xref
Search for Garmin. Nearly everyone has transducers made by airmar. The adapter outputs NMEA 2000 and the 922 is NMEA 2000 capable. So the only question is will the adapter connect to the transducer… and how to wire it.
Should be pretty easy to figure if you find your transducer and associated wiring diagram there.

Cheers to the day I see your sails on the horizon!
