I would expect that I would not receive value for the depth as it is out of the water but shouldn't the MFD acknowledge the presence of data. On my i70 when I scroll through data sources depth is light grey where as all other are black. Would a test in a bucket of water not produce any data?

Not a secure enough test to even suggest. The only thing you might check if you want to check a depth transducer out of the water is putting your hand over the transducer right when you power the system up, the depth transducer will start a high frequency click, and you can feel this and sometimes hear if very close to the bottom of the transducer. This will confirm the elements are operating within.
