Assembly
1. Attach the left release arm to the bracket back by first inserting a hex nut
into the recess in the back of the bracket. Place the arm firmly against
the bracket back and insert a #10-32x5/8" screw with a flat washer
through the holes. Tighten it in place (see Figure 1). Repeat this
procedure with the right release arm.
2. Slide the flat washer and spring onto the #10-32x2" screw and insert it
into the hole in the left release arm. Insert a nylon-insert lock nut in the
right release arm hole with the nylon side facing outward. Tighten the
screw until the spring is flush with the surface of the release arm. Do
not over-tighten.
3. P52—Attach the sensor to the bracket by placing the bracket inside
(see Figure 2). Use four #10-32x5/8" screws and flat washers. Fasten
them in place with nylon-insert lock nuts, nylon side facing outward.
Tighten the screws, so the sensor remains in place but can be adjusted.

INSTALLATION INSTRUCTIONS OWNER’S GUIDE &
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 goggles and a dust
mask 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: This is an impact release bracket only.
Attempting to manually release the bracket may cause
damage.
CAUTION: The bracket protects the sensor from frontal
impact only.
CAUTION: Never pull, carry, or hold the sensor by the
cable as this may sever internal connections.
CAUTION: Never strike the sensor.
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.

to the inside of the sensor’s
mounting tabs
