Frank - It could be that you have a tri-ducer - these include both paddle
wheel for speed, depth transducer and temperature. It is possible that you
have one of these with just the depth hooked up. Just follow the cable and
you will find out.

If it is reading a low fixed number, you may have a bad connection or the
transducer or sounder may be bad. Maybe you could borrow a transducer and
hang it over the side while plugged into your unit? This should be the best
test.

Good Luck

Hello All-
For starters, will the wise guys (and their wives) who thought I
was so stupid please google "paddle wheel transducer" and see what
comes up? Thanks.
To the others, the boat is a 1988 Grady White Seafarer with a
thru-hull transducer.The paddle wheel is located left of center about
2-3 feet forward of the stern. I do not recall the manufacturer of the
depth finder. I will check tomorrow. (Boat currently at mooring.)
There are no obvious irregularities on the hull and the boat was
just launched so no opportunity to accumulate marine growth.
The problem occurred rather suddenly.
If the transducer is mounted inside the boat, I would assume
it would be found just above the port above the paddle wheel,
correct? And could that port be clogged with barnacles even though
the paddle wheel itself appeared clean?
I will try to find that transducer and hope it is not mounted
under the gas tank!
Thanks to those who have tried to help.
Frank

It seems stuck at 2 or 2.1 feet. I checked the paddle wheel
before launch, removed the barnacles, and it spun freely.
Any ideas as to where the trouble might lie?
Thanks in advance!
