Never
install a bronze housing in a metal hull because
electrolytic corrosion will occur.

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
: 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.
WARNING
:
Retractable models
—
All the O-rings
must be intact and well lubricated to make a
watertight seal. Do not dry fit the insert in the
housing. Attempting to install the insert without
lubricating all the O-rings may damage them, possibly
preventing full insertion and a watertight seal.
WARNING
:
Retractable models
—Always attach the
safety wire to prevent the insert or blanking plug from
backing out in the unlikely event that the cap nut fails
or is screwed on incorrectly.
WARNING
:
B117 and P319
—Do not use the spacer
if there is insufficient space to tighten the nut, or it is
within 11mm (1/2") of the top of the housing.
CAUTION
: Never pull, carry, or hold the transducer by
its cable. This may sever internal connections.
CAUTION
:
Plastic housing
—Never use a fairing with
a plastic housing; the protruding sensor would be
vulnerable to damage from impact.
CAUTION
:
Metal housing
—Never install a metal
housing in a vessel with a positive ground system.
CAUTION
: Never use solvents. Cleaner, fuel, sealant,
paint, and other products may contain solvents that can
damage plastic parts, especially the transducer’s face.
CAUTION
: Never power sand or pressure wash the
sensor. It may weaken the structure or damage the
internal components.
IMPORTANT
:
Read the instructions completely
before proceeding with the installation. These
instructions supersede any other instructions in your
instrument manual if they differ.
