What are the
chances that they will work with a new sender/display unit.


About nil. A 200 Khz transducer isn't on 200 Khz...it's near 200 Khz,
nearer than 50 Khz, so they call it a 200 Khz. The impedances are also
difference, the resistance they offer the transmitter. The transmitters
and receivers are tuned at the factory to that particular transducer the
manufacturer uses. They're not universal.

Then, there's the chance the old transducer is as worn out as its
electronics. They don't last forever, either.
