I doubt there will be any takers on this unless someone has one and would like to have some back up spares. I do not know if the unit works or not and I had to cut the cable to get it out. The transducer is a paddle wheel unit and requires either a hole through the hull or transom mounting which would not be difficult to fabricate.
If you want the through hull fitting and the blank, you will have to wait until I next slip when the hole will be filled in.
First to PM me gets it. Here it is.
