I assumed this is a shoot-thru (in hull) transducer. If this is a transducer installed in a thru-hull hole, cracks have other worries, such as leaks. But thru-hull transducers don't have accompanying goo, so far as I know.
And if the crack didn't make the goo leak out, repairing /taping the housing may be all you need, as long as the transducer doesn't have an air gap.
Others would know better, but I kind of thought that transducers installed back a ways usually went in thru-hulls. Might not be original.
