Patent http://www.airmar.com/patent.html
Follow the precautions below for optimal
product performance and to reduce the risk of
property damage, personal injury, and/or death.
WARNING: Always wear safety glasses, a dust mask,
and ear protection when installing.
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 sensor by the
cable as this may sever internal connections.
CAUTION: Never strike the transducer with anything
except the palm of the hand. Never strike the
paddlewheel.
CAUTION: The bracket protects the sensor from
frontal impact only.
CAUTION: Never use solvents. Cleaner, fuel, sealant,
paint, and other products may contain solvents that can
damage plastic parts, especially the transducer's face.
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

• Recommended for boats up to 7m (22')
• Not recommended for boats with inboard engine(s)
• Not recommended for a stepped hull
• Adjusts to transom angles from 3
• Vertically orients sound beam on hull with deadrise angle up to 28
• Good operation up to 44kn (50MPH)
Pretest Temperature & Speed Functions
Connect the sensor to the instrument and spin the paddlewheel.
Check for the approximate air temperature and a speed reading. If
there is no reading(s) or it is inaccurate, check the connections
and test again. If there is still a problem, return the product to your
place of purchase.

Mounting Location

CAUTION: Do not mount the sensor in line with or near water
intake or discharge openings or behind strakes, fittings, or hull
irregularities that may disturb the water flow.
CAUTION: Do not mount the sensor in a location 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 vertical space above the bracket for it to release and
rotate the sensor upward.
• Mounting the sensor on the side of the transom where the
propeller blades are moving downward is preferred (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 the sensor at least 75mm (3")
beyond the swing radius of the propeller.
• Twin drive boat—Mount the sensor between the drives.
