Thru-Hull Transducer
Installation Instructions
Important Safety Information
WARNING
See the Important Safety and Product Information guide in the
product box for product warnings and other important
information.
The device must be installed with at least one of the included
anti-rotation bolts. Failure to do so could result in the device
rotating while the boat is moving and could cause damage to
your vessel.
You are responsible for the safe and prudent operation of your
vessel. Sonar is a tool that enhances your awareness of the
water beneath your boat. It does not relieve you of the
responsibility of observing the water around your boat as you
navigate.
CAUTION
Failure to install and maintain this equipment in accordance with
these instructions could result in damage or injury.
Always wear safety goggles, ear protection, and a dust mask
when drilling, cutting, or sanding.
NOTICE
When drilling or cutting, always check what is on the opposite
side of the surface.
This equipment should be installed by a qualified marine
installer.
To obtain the best performance and to avoid damage to your
boat, you must install the Garmin® transducer according to these
instructions.
Read all installation instructions before proceeding with the
installation. If you experience difficulty during the installation,
contact Garmin Product Support.

About the Transducer
The transducer transmits and receives sound waves through the
water, and relays sound-wave information to your Garmin sonar
device.
Mounting Location Considerations
• On outboard and sterndrive vessels À, the transducer should
be mounted in front of and close to the engine or engines.
• On inboard vessels Á, the transducer should be mounted in
front of and far away from the engine propeller and shaft.
• On step-hull vessels Â, the transducer should be mounted in
front of the first step.
May 2015
Printed in Taiwan 190-01774-02_0B
Page 2
• On full-keel vessels Ã, the transducer should be mounted at
a slight angle that aims at the bow, not parallel to the
centerline.
• On fin-keel vessels Ä, the transducer should be mounted
from 25 cm to 75 cm (from 10 to 30 in.) in front of the keel
and a maximum of 10 cm (4 in.) to the side of the centerline.
• On vessels with displacement hulls Å, the transducer should
be mounted approximately 1/3 aft of the waterline length of
the vessel from the bow, and from 150 to 300 mm (from 6 to
12 in.) to the side of the centerline.
• The transducer should be mounted parallel to the bow-stern
axis of your vessel.
• The transducer should not be mounted behind strakes, struts,
fittings, water intake or discharge ports, or anything that
creates air bubbles or causes the water to become turbulent.
The transducer must be in clean (non-turbulent) water for
optimal performance.
• The transducer should not be mounted in a location where it
might be jarred when launching, hauling, or storing.
• On single-drive boats, the transducer must not be mounted in
the path of the propeller.
The transducer can cause cavitation that can degrade the
performance of the boat and damage the propeller.
• On twin-drive boats, the transducer should be mounted
between the drives, if possible.
Fairing Block Angle Cut
A fairing block positions your transducer parallel to the water line
for increased sonar accuracy. You must measure the deadrise
angle of your boat hull to determine if a fairing block is
necessary to mount the transducer. If the deadrise angle of your
mounting location exceeds 5°, you should use a fairing block to
mount the transducer.
Deadrise Angle
Deadrise is the angle formed between a horizontal line and a
boat hull at a single point. You can measure the deadrise angle
with an angle finder, a protractor, or a digital level. You can also
ask your boat manufacturer for the deadrise angle of the specific
point on your boat hull.
NOTE: A boat may have several deadrise angles depending on
the shape of the hull. Measure the deadrise angle only at the
location where you plan to install the transducer.
Cutting the Fairing Block
CAUTION
Always wear safety goggles, ear protection, and a dust mask
when drilling, cutting, or sanding.
Using wood screws, attach the fairing block to a piece of
1
wood.
The wood becomes a cutting guide for the fairing block.
Measure the deadrise angle of the hull at the mounting
2
location.
Tilt your table saw blade À to match the deadrise angle and
3
secure the cutting fence.
NOTE: The maximum cutting angle of the fairing block is 25°.
Cut the fairing block.
6
Using a rasp or power tool, shape the fairing block to the hull
7
as precisely as possible.
Use the remaining section of the fairing block as the backing
8
block inside the hull.
Cored Fiberglass Boat Hull Installation Instructions
Thru-Hull Transducer in a Cored Hull with a Fairing Block
If the deadrise angle of your mounting location exceeds 5°, you
must use a fairing block to mount the device.
Drilling the Transducer Stem Hole and the Anti-Rotation Bolt Holes in a Cored Fiberglass Hull
Before you can drill holes for the anti-rotation bolts, you must
drill the hole for the transducer stem (Drilling the Transducer
Stem Hole and the Anti-Rotation Bolt Holes in a Cored
Fiberglass Hull) and you must cut the fairing block (Cutting the
Fairing Block).
WARNING
The device must be installed with at least one of the included
anti-rotation bolts. Failure to do so could result in the device
rotating while the boat is moving and could cause damage to
your vessel.
The core must be cut and sealed carefully to protect against
water seepage.
Select a mounting location without surface irregularities or
1
obstructions.
Using the template, mark the location of the stem hole and
2
anti-rotation bolts.
Drill a 3 mm (1/8 in.) pilot hole through the template and hull
3
at the stem hole location.
Position the fairing block on the table so the cutting guide
4
rests against the fence Á and the angle matches the angle of
the mounting location .
Adjust the cutting fence to ensure the fairing block has a
5
minimum thickness of 13 mm (1/2 in.).
2
The hole must be perpendicular to the water surface.
Place masking tape over the pilot hole and surrounding area
4
outside the hull to prevent damage to the fiberglass.
Using a 25 mm (1 in.) bit at the stem hole location, drill from
5
outside the hull through the outer skin À, inner skin Á, and
the core Â.
Page 3
The hole must be perpendicular to the water surface.
Sand and clean the inner skin, core, and outer skin around
6
the hole.
Seal the exposed inner core with epoxy Ã, and allow the
7
epoxy to set thoroughly.
While holding a drill with a 9 mm (3/8 in.) bit plumb, drill the
8
anti-rotation bolt holes through the hull from outside the hull.
The holes must be perpendicular to the water surface.
Sand and clean the area around the holes.

1
remove them.
Apply marine sealant at the base of the anti-rotation bolts and
2
transducer stem Á.
From inside the hull, slide the backing block onto the
7
transducer stem and seat it firmly against the inner hull.

From inside the hull, use slip-joint pliers or a crescent wrench
10
to secure the backing block to the anti-rotation bolts with the
included M8 nuts Ç and 8 mm washers È.

Before the sealant hardens, remove all excess sealant on the
11
outside of the fairing block and exterior hull to ensure smooth
water flow over the transducer.

1
Check whether the mounting location has an irregular surface
2
or nearby obstructions.
Select an option:
3
• If the mounting surface has no irregularities or
obstructions, make sure the template fits the mounting
location on the outside of the hull and tape the template to
the mounting location.
• If the mounting surface has irregularities or nearby
obstructions, or if the template doesn't fit the mounting
location, select a new mounting location and repeat steps
2 and 3.
Using the template, mark the location of the stem hole and
4
anti-rotation bolts.

Testing the Installation
NOTICE
You should check your boat for leaks before you leave it in the
water for an extended period of time.
Because water is necessary to carry the sonar signal, the
transducer must be in the water to work properly. You cannot
get a depth or distance reading when out of the water. When
you place your boat in the water, check for leaks around any
screw holes that were added below the water line.
Anti-Fouling Paint
To prevent corrosion on metal hulls and to slow the growth of
organisms that can affect a vessel's performance and durability,
you should apply a water-based anti-fouling paint to the hull of
your vessel every six months.
NOTE: Never apply ketone-based anti-fouling paint to your
vessel, because ketones attack many types of plastic and could
damage or destroy your transducer.
Cleaning the Transducer
Aquatic fouling accumulates quickly and can reduce your
device's performance.
Remove the fouling with a soft cloth and mild detergent.
1
If the fouling is severe, use a scouring pad or putty knife to
2
remove growth.
Wipe the device dry.
