Follow the safety precautions below to reduce
the risk of poor product performance, property
damage, personal injury, and/or death.
WARNING: Always wear safety glasses, a dust mask,
and ear protection when installing.
WARNING: Fairing—The High-Performance Fairing
requires an anti-rotation bolt. Failure to install the anti-
rotation bolt may result in the fairing rotating while the
boat is underway. The effect may be violent
movement and loss of steering.
WARNING: Fairing—The fairing must be installed
parallel to the keel to ensure proper boat handling.
WARNING: Fairing—Do not install a fairing that has
been mis-cut. Replace it. Failure to do so may result in
the fairing rotating while the boat is underway.
- Cutting the fairing at an angle greater than the
maximum allowed will cut into the sensor and/or bolt
pocket, thus weakening the fairing.
- Do not allow any gap between the fairing and the hull
that is greater than 3mm (1/8"). When the boat is
underway, water will enter any gaps and push against
the fairing with considerable force.
WARNING: Do not over tighten the hull nut and nut on
the anti-rotation bolt, crushing the hull and/or fairing.
WARNING: The O-rings must be intact and well
lubricated to make a watertight seal.
WARNING: 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: 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.
CAUTION: Never install a metal sensor in a vessel
with a positive ground system.
CAUTION: Never pull, carry, or hold the sensor by its
cable. This may sever internal connections.
CAUTION: The arrow on the top of the insert must point
forward toward the bow to align with the water flow.
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: Read the instructions completely
before proceeding with the installation. These
instructions supersede any other instructions in your
instrument manual if they differ.

Application

• Recommended for a thick hull
• Bronze housing recommended for fiberglass or wood hull.
Never install a bronze housing in a metal hull because
electrolytic corrosion will occur.
• Best performance on a hull deadrise angle through 7°
Can accommodate up to a 12° deadrise angle
• Installed with a fairing, the sensor can accommodates a
deadrise angle through 28
• Maximum hull thickness with a fairing and a 28 deadrise angle
is 47mm (1-7/8") (measured perpendicular to the water surface)

Pretest

Connect the insert to the instrument and spin the paddlewheel if
any. Check for the approximate air temperature and any speed
reading. If there is no reading(s), check all 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.
