Follow the safety precautions below to reduce the
risk of poor product performance, property
damage, personal injury, and/or death.
WARNING: A High-Performance Fairing must be
installed following the Installation Instructions that
come with the fairing. The High-Performance Fairing
requires an anti-rotation bolt. Failure to install the anti-
rotation bolt may result in the fairing rotating while the
boat is underway. The effect may be violent
movement and loss of steering.
WARNING: Always wear safety goggles and a dust
mask when installing.
WARNING: Immediately check for leaks when the boat
is placed in the water. Do not leave the boat unchecked
for more than three hours. Even a small leak may allow
considerable water to accumulate.
CAUTION: Never mount a bronze transducer in a
metal hull, because electrolytic corrosion will occur.
CAUTION: Stainless steel housing in a metal hull
requires using a Fairing Kit to isolate the stainless
steel transducer from the metal hull. Failure to do so
will cause electrolytic corrosion.
CAUTION: Never install a metal transducer on a
vessel with a positive ground system.
CAUTION: Never pull, carry, or hold the transducer by
the cable as this may sever internal connections.
CAUTION: Never strike the transducer.
CAUTION: Never use solvents. Cleaners, fuel,
sealants, paint, and other products may contain strong
solvents, such as acetone, which attack many
plastics, greatly reducing their strength.
IMPORTANT: Read the instructions completely
before proceeding with the installation. These
instructions supersede any other instructions in your
instrument manual if they differ.
Applications
• Bronze transducer recommended for fiberglass or wood hull only.
• Stainless steel transducer compatible with all hull materials.
Recommended for aluminum hulls to prevent electrolytic corrosion
provided the stainless steel transducer is isolated from the metal hull.

About Fairings
Most vessels have some deadrise angle at the mounting location. If
the transducer is mounted directly to the hull, the sound beam will
be tilted to the side at the same angle as the deadrise. A fairing is
strongly recommended if the deadrise angle exceeds 10°. Made of
a high-impact polymer with an integrated cutting guide, an Airmar
fairing is safer and easier to cut with a band saw and shape with
hand tools than custom fairings.
• Orients the sound beam straight down by mounting the
transducer parallel to the water surface.
• Mounts the transducer deeper in the water for clean flow over
the transducer's face.
• Airmar High-Performance Fairing has a long streamlined
shape, directing water around the transducer to minimize drag.
Performance is excellent above 15kn (18MPH). (To order see
"Replacement Parts" on page 4.)
