beam angle your transducer has, the smaller the inclination angle
can be. Ensure that you do not mount the transducer with a
negative inclination angle. This may cause turbulence under the
transducer face, and reduced echo sounder performance.
Summary and general recommendations
Some of the above guide lines are conflicting, and each case has
to be treated individually in order to find the best compromise.
Generally the propeller noise is the dominant factor, and a
recommended transducer location is in the fore part of the hull,
with maximum distance from the bow equal to one third of the
total length of the hull at the water line.
