I'd suggest you wait until you pull the boat out of the water and replace
it. The problem is that you can't identify it. Others have suggested ways
to determine the resonant frequency, but that won't tell you how much peak
power it will handle. I don't know how you can do that without destroying
it.

If one can determine the Resonate Frequency of the transducer, then it
would make sense to go ahead and hook up the sounder head. If it blows
the tranducer your not really out anything since it would have to be
replaced anyway, during the next haulout. If it works you save yourself
a haulout, and have a working sounder now.
