Airmar P66 Marine Transom Mount Transducer PN: 31-347-1-01.

Runs at 50/200kHz-A has 6 hole connector with 3 pins being used.

Was connected to a Garmin Fishfinder ,(not sure what model)

Should work with many older units including Raymarine,Furuno,Lowrance,

Comes with Mounting Bracket,but has small piece of plastic missing and small crack,will still mount to boat OK,I would repair with a bit of 5200 or black silicone.

Thanks for looking and good luck bidding.
