There are probably thousands of thruhull transducers in use and I have never
heard of one being punched out

Roger just doesn't want to be the first.


He wasn't - and I doubt I was, but - I had the only water intrusion on
my wreck from a punched-off mushroom on a depth sounder transducer,
allowing water to seep up the now-opened core.

It was plastic; perhaps a bronze one would have survived the
pounding. In any event, my normal bilge pumps cycled comfortably
during the several-hour tow back to the repair joint, so not much
water was able to get between the core and the hull-hole.

So, there's one which was defective, later, in that same hole (I had a
replacement), and one which is an inside, shoot-through-the-hull
mounted next to it.

If I ever have the same wreck, I'll have the same potential for water
intrusion :{)) - but I'll still have a functioning sounder from the
inside!
