Have a GP1971F plotter on a NMEA 2000 network, have been looking for a transducer it. Was thinking of a 525T-LTD12, but like to find a transducer that would plug into the network. Have a 2 3/8" hole and a 14.5 deadrise.
The best way would be to select a transducer that goes direct to the sounder 10 pin connection and not the NMEA 2000 bus.
The 525T-LTD/12 (B60) will go direct to the sounder but you will need to check the sizing with Airmar because I believe it needs a little be larger hole than what you quoted.
