Using old transducer - 2009/06/12 12:05
Pete,
Electronically, if the old transducer is the same frequency and same impedance, it would likely work, as long as you can power it up correctly, but it would be a "Rube Goldberg" Kludge. Pinout conversion will require getting proper pinouts and schematics for both the old and new units.
Transducers need to be replaced from time to time, so I would avoid a permanent glassed-in installation. In 15 years, I have changed out my 'ducer twice. If possible, I would recommend using the factory thru-hull and transducer, as it will make ongoing reliability and troubleshooting much easier.
