Follow the precautions below for optimal
product performance and to reduce the risk of
property damage, personal injury, and/or death.
WARNING: Installation of the anti-rotation studs/screws
is mandatory! The anti-rotation studs/screws hold the fairing
firmly in place. Failure to install the anti-rotation studs / screws
may result in the fairing rotating while the boat is underway.
The effect may be violent movement and loss of steering.
WARNING: The transducer must be installed parallel to
the keel/centerline to ensure proper boat handling and
water flow under the transducer.
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 in the water
unchecked for more than three hours. Even a small leak
may allow a considerable amount of water to accumulate.
WARNING: SS141L-TS with Fairing—The fairing must
be screwed to a block of wood before cutting. It is too thin
to cut safely without additional material. Failure to do so
may result in the fairing moving on the band saw.
WARNING: Fairing—Do not install a fairing that has
been mis-cut. Replace it.
Cutting the fairing at an angle greater than the
maximum allowed will cut into the transducer and/or
anti-rotation pockets, thus weakening the fairing.
Do not allow any gap between the fairing and the hull
that is greater than 1.5mm (1/16"). When the boat is
underway, water will enter any gaps and push against
the fairing with considerable force, possibly rotating it.
WARNING: Fiberglass hull—The transducer must be
installed in solid fiberglass, not in coring.
CAUTION: Never install a metal transducer on a vessel
with a positive ground system.
CAUTION: Never pull, carry, or hold the transducer by
the cable as this may sever internal connections.
CAUTION: Never strike the transducer.

PN:___________________Date___________Frequency________kHz
Applications
Stainless steel is compatible with all hull materials. Recommended
for aluminum hulls to prevent electrolytic corrosion, provided the
stainless steel transducer is isolated from the metal hull.
Recommended for boats capable of speeds up to 30kn
(35MPH). Optimal speed is 1.5 - 8.5 kn (2 - 10MPH).
A fairing is strongly recommended if the deadrise angle of the
hull exceeds 10°. The fairing can accommodate a deadrise
angle of up to 22°.

CAUTION: Stainless steel transducer in a metal hull
Stainless steel must be isolated from a metal hull to
prevent electrolytic corrosion. Use the isolation sleeving
supplied.
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.

Summary

General Safety Precautions and Warnings

Mandatory Anti-Rotation Studs

Ensures the fairing remains firmly in place to prevent violent movement or loss of steering.

Transducer Alignment and Water Flow

Install parallel to the keel for proper boat handling and water flow under the transducer.

Personal Protective Equipment

Always wear safety glasses, a dust mask, and ear protection during installation.

Immediate Leak Check

Check for leaks within three hours of placing the boat in water.

Fairing Cutting and Installation

Ensure proper cutting and fit of the fairing to prevent gaps and water ingress.

Hull Material Precautions

Specific warnings for fiberglass hulls and metal transducer installation.

Solvent Usage Warning

Avoid solvents which can damage plastic parts, especially the transducer face.

Applications and Compatibility

Hull Material Compatibility

Stainless steel is compatible with all hull materials; recommended for aluminum.

Recommended Boat Speeds

Suitable for speeds up to 30kn (35MPH), optimal speed is 1.5-8.5 kn (2-10MPH).

Fairing for Deadrise Angles

A fairing is recommended for hulls with deadrise angles exceeding 10°, accommodating up to 22°.

Mounting Location Guidelines

Avoid Water Flow Disturbances

Do not mount near water intakes, discharge openings, or hull irregularities.

Protection During Handling

Avoid mounting locations susceptible to damage during trailering or launching.

Smooth Water Flow Requirements

Ensure smooth water flow with minimum bubbles and turbulence under the transducer.

Minimize Interference Sources

Choose a location away from propellers, shafts, and other machinery or echosounders.

Consider Hull Deadrise

Choose a location with a minimal deadrise angle for optimal performance.

Mounting on Different Boat Types

Guidelines for planing, outboard, inboard, stepped, and displacement hulls.

Installation Procedure

Cutting the Fairing

Detailed steps for shaping the fairing to match the hull using a band saw.

Hole Drilling for Fiberglass Hull

Drilling pilot holes and main holes for transducer and studs in cored fiberglass.

Hole Drilling for Metal Hull

Drilling and preparing holes for transducer and studs in metal hulls.

Bedding and Sealing Installation

Surface Preparation

Ensure all surfaces to be bedded are clean and dry before applying sealant.

Applying Marine Sealant

Apply sealant to transducer, fairing, backing block, and hull nut contact surfaces.

Installing Anti-Rotation Studs

Screw in anti-rotation studs, applying sealant and tightening with slip-joint pliers.

Metal Hull Isolation Sleeving

Use isolation sleeving for transducer stem and studs in metal hulls to prevent corrosion.

Final Assembly and Checks

Tightening Nuts

Secure hull nut and anti-rotation stud nuts using slip-joint pliers, avoid over-tightening.

Fairing Gap Sealant

Fill any gaps between fairing and hull with sealant; replace if gap exceeds 1.5mm.

Removing Excess Sealant

Ensure smooth water flow by removing excess sealant from outside surfaces.

Cored Fiberglass Hull Installation Details

Core Preparation and Sealing

Cut and seal the core to prevent water seepage and hull crushing.

Reinforcing the Hull

Use casting epoxy to reinforce the hull around the drilled holes for the transducer.

Cable Routing and Connections

Cable Routing Precautions

Route cable carefully, use grommets, and separate from electrical wiring to prevent damage.

Connecting to Module

Refer to module instructions for connecting the transducer to the LSS-2 or 3D module.

Post-Installation Checks and Maintenance

Leak Checking Procedure

Immediately check for leaks and re-bed if any are found; do not leave unchecked for long.

Anti-fouling Paint Application

Apply water-based anti-fouling paint every 6 months or seasonally to exposed surfaces.

Transducer Cleaning

Clean aquatic growth with a scour pad and detergent; lightly wet sand if fouling is severe.

Ordering Replacement Parts

Record information from the cable tag for ordering replacement parts.
