Looking for other 300 DA's

[300DA]

I've been looking for any information on the original sounder and the dimensions and type and model numbers for the thru hull transponder and what equipment i can connect to it.

just now seeing this about 5 months too late! I'm guessing you already got your answer? My boat had a Lowrance in it and it died about 8 years ago. I removed it quite easily! The transducer was not a thru hull and was probably added by a PO at some point. Shoot me a PM if you have additional questions!
