5200 removal

[CHANCE1234]

My airmar B60 20 degree thru hull transducer has failed after only 2 years and maybe 80 hours underway. Earlier this week it stopped working. I suspected the garmin 740s plug but no fix there. So than I simply touched the wire coming out of the ducer and it started to work until I touched it again. Today it won't work no mater what I do to the wire. I emailed airmar to see if they have any warranty. I bought it new through west marine. But back to my question, how do I remove this ducer with all the 5200? Anyone had to do this? Thanks for any help.
