Interesting. I used a piece of PVC pipe slightly larger than the sensor. I
cut the PVC at a slight angle, so it would sit flush against the side of the
bilge, then epoxied it in place so it would hold fluid. I put the sensor on
another piece of PVC with a small groove on it and the pipe so it would stay
in the right orientation, put in the oil, then put the sensor/piece combo
in, and put a cap on (unglued). The cap keeps the mineral oil from sloshing
out.

I have a very old DataMarine unit. The transducer is a hemi-sphere the size
of a bowling
ball (1/2 full of water), glued to the hull (of a Ranger 33 sailboat).
The display had
Numitron display tubes, but they failed and I had to replace them with
LEDs. It works
fine.

Which one do you have? I had a low-end fishfinder. Just sold the boat, and
I
can't remember the brand.

A number of people on the Tanzer list simply caulked glued the
transducer to the hull. Doesn't have to be straight up and down, just a
good, solid connection.

Mine has water in it (and that's what was specified).
