Hi
I'm in the midst of swapping boats. "New" one is clinker, and has an
existing through-hull transducer. No visible markings, and no plug on the
end of the cable.
I've an existing Lowrance X48 complete with transom mount transducer. I'd
prefer not to use the transom mount -it means another hole in the boat -
there are enough of those already. And I'm not going to slip the boat just
to change the transducer. I know from past experience that the signal
firing through the planking is virtually useless.
If I can find another plug for the Lowrance, can I use the existing
transducer? If it doesn't work, will I damage the Lowrance? Any way to
test for compatibility? My multimeter can measure capacitance, for what
that's worth.

Airmar (see http://www.airmar.com/index1.html) makes many (maybe most)
of the transducers used on depth sounders and fishfinders from all the
popular brands on an OEM basis. I asked them exactly the same question
when we bought Fintry, but I had the advantage that I knew what the
old unit was. They can certainly answer your question, but only if you
know something about the transducer. Sounds like you don't know much.

I would guess, however that the answers a
Will it work? Probably not.
Will it damage the Lowrance? Probably not.
Can I test? Maybe. Get someone with the right equipment to measure
the transducer impedance of both at the Lowrance's frequency. If
they're similar, you stand a chance.

How about hanging the transom mount on with a clamp or something
similar until you next slip the boat?
