I took some pics at the lake with my cell phone and they are crap. I will post anyway. I am doing a tear-down now for water leaks. There was a little, not much but concerning in the tube. It appears that the stuffing box has not been refreshed in some time - maybe never so I picked up some marine grease and filled tonight. I will shoot some pics of it torn down so you can see the decoder in place of the receiver and the umbilical connection.
cheers
