Transom Mount
with Integrated Release Bracket
TRIDUCER
®
Multisensor
Model:
P58
Patent http://www.airmar.com/patent.html
Applications
• Recommended for boats up to 8m (25') long
• Not recommended for boats with inboard engine(s)
• Not recommended for a stepped hull
• Adjusts to
transom
angles from 3
–20
• Vertically orients sound beam on hull with
deadrise
angle up to 28
• Requires a minimum of 89mm (3-1/2") of vertical space to install
• Good operation up to 44kn (50MPH)
Pretest Speed & Temperature Functions
Connect the sensor to the instrument and spin the paddlewheel.
Check for a speed reading and the approximate air temperature. If
there is no reading(s) or it is inaccurate, check the connections
and repeat the test. If there is still no reading(s) or it is inaccurate,
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 (Figure 1).
• Mounting the sensor on the side of the transom where the
propeller blades are moving downward is preferred (Figure 2).
• 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.
•
Trim tabs
—Mount the sensor inside the trim tab, space
permitting.
•
Stepped transom
—Mount the sensor on the lowest step
being sure there is enough space above the bracket for it to
release and rotate the sensor upward (Figure 1).
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 sensor from frontal
impact only.
CAUTION
: Never use solvents. Cleaners, 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.
