Raymarine depth transducer plug wanted

[Plum]

Hi, I have a Raymarine DS500x fishfinder and i wish to connect a different transducer to it. Does anyone have a spare 7-pin plug I can fit to the end of the transducer cable that will plug into the back of the fishfinder, or an old transducer that I can cut the plug off of and graft the two cables together. See attached picture of the socket on the back of the fishfinder.
