I noticed that the site I just mentioned sells O-rings for the
Datamarine transducer. I think that is what I may have seen
protruding out around the base of the transducer housing.
Couldn't tell what it was at first, but certainly if that's what it
was, bilge water could get in. Am I on to something? And
what would cause an O-ring to pop out of place or stretch
like that?

I'm guessing Datamarine is out of business, but
depth replacement cores are found at

Could this be what I need?

I now have full info on the depth finder that many of you requested
when initially trying to help me solve my problem.
The unit is a Datamarine LX201. With the input connected (RCA
plug) the display always reads 2 or 2.1 feet. (I checked to make sure
the plug was properly seated.) With the plug disconnected, the
display reads "MSD" and only a decimal point is shown. I assume
this is normal.
The transducer housings are located just forward of the engine.
The coax to the depth transducer (starboard side) appears to have no
splices. The speed transducer (paddle wheel) lies on the port side.
Both transducers show a housing that's about 2" in diameter and the
wires are molded in. (The speed transducer appears a little taller.)
Both appear to have screw threads and large "wing nuts" that are
marked "hand tight."
The coax from the speed transducer terminates in a coaxial
fitting in the instrument compartment, which means I could have
a speedometer if I wanted one.
More than you wanted to know, but that's it. I'm suspicious that
the depth transducer itself is faulty, but what are your thoughts? And
if you think it is, how easy to replace?
Your help is always very much appreciated!!
