Installation Instructions
Important Safety Information
WARNING
See the Important Safety and Product Information guide in the
chartplotter or fishfinder product box for product warnings and
other important information.
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.
To obtain the best performance and to avoid damage to your
boat, you must install the Garmin® device according to these
instructions.
Read all installation instructions before proceeding with the
installation. If you experience difficulty during the installation,
contact Garmin Product Support.
• When the transducer moves through the water, bubbles
stream behind the transducer in a “V” shape À. The size and
area of this "V" shape is affected by factors such as your boat
speed and the angle of the transducer mount. You should
mount the transducer in a location that does not introduce air
into the path of propellers Á. Introducing air into the
propellers may severely impact acceleration and top speed
performance, and can damage the propellers and engines.
Mount the transducer far enough to the port or starboard side
away from the propeller(s) to avoid this effect. This effect is
greater if the transducer is aligned vertically with the path of
the propellers. Consider the turning radius of the propellers of
an outboard or stern drive. For most installations, it is not
recommended to mount the transducer between the engines
of a multi-engine arrangement. The transducer is shown from
above.
• When mounted farther from the center of the transom, a
greater deadrise can cause the boat hull À to interfere with
the sonar beam Á, and can cause inconsistent detection on
the opposite side of the boat Â. The transducer is shown
from behind.
Mounting Considerations
This mount is not usable for all boat hulls. Review these
considerations to determine compatibility with your boat type.
Poor transducer location may result in poor transducer
performance or impact the handling of the boat.
• The transducer should not be mounted in a location where it
might be jarred when launching, hauling, or storing.
• The transducer should not be mounted behind strakes, struts,
fittings, water intake or discharge ports, in-hull transducers,
or anything that creates air bubbles or causes the water to
become turbulent. Turbulent water may interfere with the
sonar beam.
• The transducer must be mounted with the transducer face
submerged and facing forward. The transducer shape
requires a larger surface area to be submerged than a typical
transom-mounted transducer. The large submerged surface
area creates drag that can impact the boat's handling and top
speed, ranging from a negligible drag to unacceptable drag.
You may need to adjust your boat's trim tabs if the transducer
is not mounted in the center of the transom. For optimal
results, the transducer should be mounted as close to the
center line as possible.

Operating Considerations
When operating at speeds greater than 12.9 km/hr (8 mph), the
performance of the transducer is limited, the bottom return is
diminished, and the depth information and alarm may not
provide warnings for potential shallow depth areas.
You should operate your boat slowly in shallow water or in areas
of unknown depth or underwater obstructions.
When enabled, the forward depth alarm sounds in shallow
bottom areas. Suspended or narrow underwater obstructions
may not be identified as the bottom and may not trigger the
alarm. The alarm is not guaranteed to prevent collisions. You
should always use caution when operating your boat.
Effective Forward Range
The transducer has an effective forward range of between five
and eight times the depth of the water. For example, in 3 m
(10 ft.) of water, the effective forward range is between 15 and
24 m (between 50 and 80 ft.). Water conditions and bottom
conditions affect the actual range. You should use caution and
observe the water depth and forward range, especially when
your device is in manual forward range mode.
Software Update
You may need to update the device software when you install
the device or add an accessory to the device.
Loading the New Software on a Memory Card
You must copy the software update to a memory card using a
computer that is running Windows® software.
NOTE: You can contact Garmin customer support to order a
preloaded software update card if you do not have a computer
with Windows software.
Insert a memory card into the card slot on the computer.

Go to www.garmin.com/support/software/marine.html.
2
Select Download next to the software bundle that
3
corresponds with your chartplotter.
NOTE: The software download includes updates for all
devices connected to the chartplotter. Select the correct
bundle that corresponds to the chartplotter to be updated.
You can select See All Devices in this Bundle to confirm the
devices included in your download.
Read and agree to the terms.
4
Select Download.

If necessary, select Run.
6
If necessary, select the drive associated with the memory
7
card, and select Next > Finish.
Extract the files to the memory card.
8
NOTE: The software update can take several minutes to load
onto the memory card.
Updating the Device Software
Before you can update the software, you must obtain a
software-update memory card or load the latest software onto a
memory card.
Turn on the chartplotter.
1
After the home screen appears, insert the memory card into
2
the card slot.
NOTE: In order for the software update instructions to
appear, the device must be fully booted before the card is
inserted.
Follow the on-screen instructions.
3
Wait several minutes while the software update process
4
completes.
When prompted, leave the memory card in place and restart
5
the chartplotter manually.
Remove the memory card.

Installing the Transducer on a Transom
Aligning the Transom-Mount Hardware on the Boat
Place the transom-mount on the boat transom À 13 mm
1
(1/2 in.) Á from the bottom of the hull.
Insert a shear screw  into the transom-mount bracket in a
2
hole that keeps the housing bracket parallel to the water line
.
Ã
Using the transom-mount bracket as a template, mark the
3
location of the holes.
Remove the bracket.
4
Add the nut to the shear screw and tighten.
5
NOTE: When installed in the bracket, the shear screw and
nut may appear loose.
Tighten the M10 bolt Ä.
6
NOTE: The maximum torque applied to the M10 bolt should
not exceed 51.5 N-m (38 lb-ft.).
Installing the Transom-Mount Hardware on the Boat
If you are installing the bracket on fiberglass, place a piece of
1
tape over the pilot-hole location to reduce cracking of the gel
coat.
Using a 4 mm (5/32 in.) drill bit, drill the pilot holes.
2
Slide the deflection shield bracket À over the transom-mount
3
bracket.
