Mounting the Transducer to the Hull
When mounting transducers, the goal is to make 100% contact between the transducer and the
hull. The better you prepare the surface, the better the result.
To make a neat and tidy installation, proceed as follows:-
1. Degrease the general area where mounting the transducer and also degrease the face of
the transducer using either isopropyl alcohol, methylated or surgical spirit.
2. Draw a pencil circle around base of transducer as photograph number one below, abrade
hull within this circle using medium grade sandpaper. Mask around circle as in the
photograph two below. Also mask lower part of the transducer.
3. Following the Devcon instructions, install each transducer one at a time. Place transducer in
center of masked area and push down hard to expel surplus Devcon. Masking tape should
be used during bonding to keep the transducers in place on sloping parts of the hull. After
about three minutes, depending on temperature, run around perimeter of transducer with a
sharp pointed blade and ease surplus away.
4. Allow 1 hour for Devcon to set before removing the masking tape which should come away
with the surplus Devcon. Take care not to disturb transducer during the above process while
the Devcon sets.
