2. INSTALLATION OF TRANSDUCERS
2-2
Transducer mounting locations
Installation procedure
1. With the boat hauled out of the water, mark the location chosen for mounting the
transducer on the bottom of the hull.
2. If the hull is not level within 15° in any direction, fairing blocks made out of teak
should be used between the transducer and hull, both inside and outside, to keep
the transducer face parallel with the water line. Fabricate the fairing block as
shown below and make the entire surface as smooth as possible to provide an un-
disturbed flow of water around the transducer. The fairing block should be smaller
than the transducer itself to provide a channel to divert turbulent water around the
sides of the transducer rather than over its face.
3. Drill a hole just large enough to pass the threaded stuffing tube of the transducer
through the hull, making sure it is drilled vertically.
4. Apply a sufficient amount of high quality caulking compound to the top surface of
the transducer, around the threads of the stuffing tube and inside the mounting
hole (and fairing blocks if used) to ensure watertight mounting.
