2 Fishfinder 250/250C Owner’s Manual
Transducers
The transducer acts as the eyes and ears of your sonar, transmitting
sound waves toward the bottom in a cone shape. Proper transducer
selection and installation are important to the operation of your unit.
Select a transducer that suits the depth of the water that you are on.
A wide cone angle transducer works best in shallower water,
providing a large coverage or viewing area, but at a decreased
bottom resolution. In deep water this can result in a large area
where fish cannot be seen. A narrow cone angle transducer is better
suited to deep water installations, providing a smaller coverage or
viewing area than a wide cone transducer, but with improved bottom
resolution and a smaller dead zone.
Optional Transducers
Included in the Optional Packages (page 1) are transom mount
transducers and separate speed sensors. These transducers provide
good all-around performance. In addition, a variety of optional
transducers are available from your local dealer or direct from
Garmin.
• 200/50kHz, 12/45°, plastic, transom mount, depth, temp
• 200/50kHz, 12/45°, plastic, transom mount, depth, temp, speed

2 Fishfinder 250/250C Owner’s Manual
Installation
The Fishfinder 250/250C must be properly installed according to
the following instructions to get the best possible performance. To
complete the installation, you need the appropriate fasteners and
tools. Verify that all cables can reach the unit mounting location, and
take time to read through these instructions prior to installation. Be
sure to always wear safety goggles and a dust mask when drilling,
cutting, or sanding. If you experience difficulty installing the unit,
contact Garmin Product Support or seek the assistance of a
professional installer.
Selecting a Proper Location
Choose a location that provides optimal viewing as you operate
the vessel and allows easy access to the unit’s keypad. Select a
mounting surface capable of supporting the weight of the unit and
protecting it from excessive vibration and shock. DO NOT mount
the unit in an area exposed to extreme temperature conditions. When
installing the mounting bracket, allow room for the routing and
connection of the power and transducer cables.
Installing the Swivel Mount
The Fishfinder 250/250C’s compact, waterproof case is suitable
for mounting in exposed locations or at the nav station. The unit
comes with a swivel-mount bracket that can be used for console or
overhead mounting.
When choosing a location for the unit, consider the following
conditions:
• There should be at least a 3” (8 cm) clearance behind the case
to allow connection of the transducer and power/data cables.
• The mounting surface should be sturdy enough to support the
unit and protect it from excessive vibration and shock.
NOTE: The temperature range for the Fishfinder 250/250C
is 5°F to 130°F (-15°C to 55°C). Extended exposure to
temperatures outside this range (in storage or operating
conditions) may cause failure of the LCD screen. This type
of failure and related consequences are NOT covered by the
manufacturer’s limited warranty.

To install the swivel-mount bracket:
Tools (not included)—Drill, screwdriver (Phillips or
standard), and either of the following:
• Three #8 (4mm) pan head machine bolts with matching
nuts and washers and a 5/32” (5mm) drill bit.
• Three #8 pan head self-tapping screws and an
appropriately-sized drill bit for drilling starter holes.
1. Using the swivel base as a template, mark the location of
the three holes that are used to secure the bracket to the
mounting surface.
2. Drill the mounting holes.
• If securing the base with machine bolts, drill three 5/32”
(5mm) holes at the locations you marked.
• If securing the base with self-tapping screws, drill starter
holes at the locations you marked. Starter holes should
generally be no deeper than half the screw length.
3. Secure the swivel base with three bolts or screws. DO NOT
OVERTIGHTEN.
4. Place the rest of the mount over the swivel base and secure
with the short knob.
OK
The swivel base is designed to be secured using a pan head screw
or machine bolt. If you use a screw with a countersunk head, you risk
damaging the mounting bracket.
Secure the base and attach the mount.

To install the unit on the bracket
1. Align the slot on the back of the unit with the long mounting
knob, and slide the unit into place. You may need to adjust
the long mounting knob to spread the bracket arms apart.
(Turn counter-clockwise to widen the bracket arms, clockwise
to tighten.)
2. Adjust the unit angle and tighten the long mounting knob until
snug.
3. To tilt the unit, loosen the long mounting knob on the right
side of the bracket assembly.
4. To rotate the entire bracket, twist it left or right. The bracket
clicks as you turn it.
5. Tighten all knobs once the desired viewing angle is obtained. Slide the unit onto the bracket.
Adjust for optimal viewing.

Flush Mounting the Fishfinder 250/250C Unit
The Fishfinder 250/250C can be flush mounted on a flat panel. When
flush mounting the Fishfinder 250/250C, choose an appropriately
sized location for the unit. Use the Flush Mount Template provided
in the box to determine a location. Check that all cables reach the
unit mounting location before beginning installation. Always wear
safety goggles and a dust mask when drilling, cutting, or sanding.
To flush mount the Fishfinder 250/250C:
Included mounting hardware—Four 3mm studs, four flat
washers, and eight 3mm hex nuts.
Tools (not included)—Center punch, drill, 1/8” (3mm) drill bit,
3/8” (6mm) drill bit, jig saw, 1/16” (2mm) Allen wrench, and
9/32” (7mm) wrench.
1. Trim the Flush Mount Template and tape it in the appropriate
location.
2. Using a center punch, indent the center of each mounting
hole location.
3. Using a 1/8” (3mm) drill bit, drill the four mounting holes.
4. Using a 3/8” (6mm) drill bit, drill a hole for a location to begin
cutting the mounting surface.
5. Using the jig saw, cut the mounting surface along the inside
of the dashed line indicated on the template.
NOTE: Be very careful when cutting this hole; there is only a
small amount of clearance between the unit and the mounting
holes. It may be prudent to cut slightly inside the indicated line
and then sand or file the panel as needed to obtain the best fit.
6. Install the four mounting studs into the unit by screwing the
shorter section into the back of the unit. Use a 1/16” (2mm)
Allen wrench to tighten the mounting studs until the stops
contact the case. Be careful not to overtighten, as this may
damage the mounting stud. The studs have a reusable
thread-locking patch pre-
applied from the factory.
7. Place the unit in position
inside the cutout area of
the mounting surface.
8. Place washers over the
mounting studs, then
thread on one hex nut per
mounting stud. Tighten
all four hex nuts until the
unit is snug against the
mounting surface. Install
and tighten the second hex
nut on all four mounting
studs to lock the first hex nut in place.
