Hi people,
I think I'm likely having a senior moment in my old age but I assembled the Transom Mount transducer mount and clicked it all into place and now i can't get it apart to fit it, no matter how I try to do what the instructions say...or maybe I'm too frightened I'll break it.

Can someone please advise me the easiest way to pull this mount to pieces again - I can't get it to open as if it hit an obstruction and snapped upwards?

Please help. Thanks.
