There has been a continuing low level of discussion on "where to install the
depth-sounder transducer".
One recommended way has been to install it in a liquid-filled well
glued/cemented/epoxied inside the hull. Several comments have observed the
need for moving the transducer around to find the best location. Other
comments have stressed not operating the transducer in free air - it must be
loaded (impedance matched). I found the note below on a Mac 26 site and
thought it might be of interest. This person apparently bedded his
transducer directly into plumber's putty against the hull. One might also
bed a piece of PVC pipe and fill it with water as an easily-moved trial
location.
Offered without recommendation, FWIW

"Installing a depthfinder, I used a regular fish finder and mounted the
display just inside the companion way on an L bracket, This also swings out
of the way. I mounted the sender in the cooler compartment about 4 inches
out from the centerboard, it shoots thru the hull, at first I stuck it there
with plumbers putty and it worked OK. I do plan to glass it down later. I
think my total cost was about $90.00"
