Airmar P66 Owner's Manual & Installation Instructions

OWNER' S GUIDE
Transom-Mount Transducer
or TRIDUCER
U. S. Patents: 5,606,253; 5,719,824
WARNING: Always wear safety goggles and a dust
mask when installing to prevent personal injury.
WARNING: When the boat is placed in the water,
immediately check for leaks around the screws and
any other holes drilled in the hull.
CAUTION: Never pull, carry, or hold the transducer by
the cable as this may sever internal connections.
CAUTION: Never strike the multisensor with anything
except the palm of the hand. Never strike the paddlewheel.
CAUTION: Never use solvents. Cleaners, fuel, paint,
sealants, and other products may contain strong
solvents, such as acetone, which attack many plastics
greatly reducing their strength.
IMPORTANT: Please read the instructions completely
before proceeding with the installation. These
instructions supersede any other instructions in your
instrument manual if they differ.

Applications
• Not recommended for boats with large inboard engine(s)
• Not recommended for stepped hull
• Good operation up to 44kn (50MPH)
• Vertically orients sound beam on hull with deadrise angle up to 30°
• Adjusts to transom angles from 2
• Bracket protects sensor from frontal impact only
Mounting Location
CAUTION: Do not mount in an area of turbulence or bubbles:
near water intake or discharge openings; behind strakes, struts,
fittings, or hull irregularities
CAUTION: Avoid mounting the sensor where the boat may be
supported during trailering, launching, hauling, or storage.
• For the best performance, the sensor must be in contact with smooth
water. To identify an area of clean water, observe the water flow off the
transom while the boat is underway.
• Allow headroom space above the bracket for it to release and rotate the
sensor upward (see Figure 1).
• Mount the sensor as close to the centerline (keel) of the boat as
possible to ensure the sensor remains in the water when the boat is
turning.
• Single drive boat—Mount at least 75mm (3") beyond the swing
radius of the propeller (see Figure 2). The starboard side where the
propeller blades are moving downward is preferred.
• Twin drive boat—Mount the sensor between the drives.
