Installation & Accessories
Preparations
You can install the sonar in some other order if you prefer, but we recommend this installation sequence:
Caution:
You should read over this entire installation section before drilling any holes in your vehicle or vessel!
1. Determine the approximate location for the sonar/GPS unit, so you
can plan how and where to route the cables for the transducer and
power. This will help you make sure you have enough cable length for
the desired configuration.
2. Determine the approximate location for the transducer and its cable
route.
3. Determine the location of your battery or other power connection,
along with the power cable route.
4. Install the transducer and route the transducer cable to the sonar/GPS unit.
6. Install the power cable and route it to the sonar/GPS unit.
7. Mount the sonar/GPS unit to the bracket.
Transducer Installation
These instructions will help you install your Skimmer
®
transducer on a
transom, on a trolling motor or inside a hull. These instructions cover
both single- and dual-frequency Skimmer transducers. Please read all
instructions before proceeding with any installation.
The smaller single-frequency Skimmers typically use a one-piece,
stainless steel mounting bracket. The larger dual-frequency Skimmers
typically use a two-piece, plastic mounting bracket. The trolling motor
mount uses a one-piece plastic bracket with an adjustable strap.
6
These are all "kick-up" mounting brackets. They help prevent damage if the
transducer strikes an object while the boat is moving. If the transducer does
"kick-up," the bracket can easily be pushed back into place without tools.
Read these instructions carefully before attempting the installation.
Determine which of the mounting positions is right for your boat. Re-
member, the transducer installation is the most critical part of
a sonar installation.
NOTE:
The following installation types also call for these recommended
tools and required supplies that you must provide (supplies listed
here are not included):
Single-frequency transom installations
Tools include: two adjustable wrenches, drill, #29 (0.136") drill bit,
Phillips head screwdriver. Supplies: high quality, marine grade aboveor below-waterline sealant/adhesive compound.
Dual-frequency transom installations
Tools: two adjustable wrenches, drill, #20 (0.161") drill bit, Phillips head screwdriver. Supplies: four, 1" long, #12 stainless steel slotted wood screws, high
quality, marine grade above- or below-waterline sealant/adhesive compound.
Single-frequency trolling motor installations
Tools: two adjustable wrenches, Phillips head screwdriver. Supplies:
plastic cable ties.
Selecting a Transducer Location
1. The location must be in the water at all times, at all operating speeds.
2. The transducer must be placed in a location that has a smooth flow
of water at all times. If the transducer is not placed in a smooth flow of
water, interference caused by bubbles and turbulence will show on the
sonar's display in the form of random lines or dots whenever the boat is
moving.
7
NOTE:
Some aluminum boats with strakes or ribs on the outside of the
hull create large amounts of turbulence at high speed. These boats
typically have large outboard motors capable of propelling the boat
at speeds faster than 35 mph. Typically, a good transom location on
aluminum boats is between the ribs closest to the engine.
3. The transducer should be installed with its face pointing straight
down, if possible.
4. If the transducer is mounted on the transom, make sure it doesn't
interfere with the trailer or hauling of the boat. Also, don't mount it
closer than approximately one foot from the engine's lower unit. This
will prevent cavitation (bubble) interference with propeller operation.
5. If possible, route the transducer cable away from other wiring on the
boat. Electrical noise from engine wiring, bilge pumps and aerators can
be displayed on the sonar's screen. Use caution when routing the transducer cable around these wires.
Good and poor transducer locations.
CAUTION: Clamp the transducer cable to transom near
the transducer. This will help
p
revent the transducer from
entering the boat if it is
knocked off at high speed.

How low should you go?
For most situations, you should install your Skimmer transducer so
that its centerline is level with the bottom of the boat hull.
This will usually give you the best combination of smooth water flow
and protection from bangs and bumps.
Align transducer centerline with hull bottom.
However, there are times when you may need to adjust the transducer
slightly higher or lower. (The slots in the mounting brackets allow you
to loosen the screws and slide the transducer up or down.) If you frequently lose bottom signal lock while running at high speed, the transducer may be coming out of the water as you cross waves or wakes.
Move the transducer a little lower to help prevent this.
If you cruise or fish around lots of structure and cover, your transducer
may be frequently kicking up from object strikes. If you wish, you may
move the transducer a little higher for more protection.
There are two extremes you should avoid. Never let the edge of the
mounting bracket extend below the bottom of the hull. Never let the
bottom – the face – of the transducer rise above the bottom of the hull.
Transom Transducer Assembly And Mounting
The best way to install these transducers is to loosely assemble all of the
parts first, place the transducer's bracket against the transom and see if
you can move the transducer so that it's parallel with the ground.

The following instructions sometimes vary depending on the mounting
bracket that came with your transducer. Single-frequency Skimmers come
with a one-piece stainless steel bracket, while dual-frequency Skimmers
come with a two-piece plastic mounting bracket. Use the set of instructions that fits your model.
1. Assembling the bracket.
A. One-piece bracket: Press the two small plastic ratchets into the
sides of the metal bracket as shown in the following illustration. Notice
there are letters molded into each ratchet. Place each ratchet into the
bracket with the letter "A" aligned with the dot stamped into the metal
bracket. This position sets the transducer's coarse angle adjustment for a
14° transom. Most outboard and stern-drive transoms have a 14° angle.
Align plastic ratchets in bracket.
B. Two-piece bracket: Locate the four plastic ratchets in the trans-
ducer's hardware package. Press two ratchets into the sides of the plastic bracket and two on either side of the transducer as shown in the following illustrations. Notice there are letters molded into each ratchet.
Place the ratchets into the bracket with the letter "A" aligned with the
alignment mark molded into the bracket. Place the ratchets onto the
transducer with the letter "A" aligned with the 12 o'clock position on
the transducer stem. These positions set the transducer's coarse angle
adjustment for a 14° transom. Most outboard and stern-drive transoms
have a 14° angle.

2. Aligning the transducer on the transom.
To align the transducer to the transom, side the transducer between
the ratchets. Look at the transducer from the side and adjust it so that
its face is parallel to the ground. The alignment letters on either side of
the bracket need be the same.

If the transducer's face isn't parallel with the ground, remove the
transducer and ratchets from the bracket. Place the ratchets into the
holes in the bracket with the letter "B" aligned with the dot stamped in
the bracket.
Reassemble the transducer and bracket and place them against the
transom. Again, check to see if you can move the transducer so it's parallel with the ground. If you can, then go to step 3A.
3. Assembling the transducer.
A. One-piece bracket: Once you determine the correct position for
the ratchets, assemble the transducer as shown in the following figure. Don't tighten the lock nut at this time.
Position transducer mount on transom and mark mounting holes. Side
view shown (left) and seen from above (right).

B. Two-piece bracket: Once you determine the correct position for
the ratchets, assemble the transducer as shown in the figure in step
2B. Don't tighten the lock nut at this time.

4. Drilling mounting holes.
Hold the transducer and bracket assembly against the transom. The
transducer should be roughly parallel to the ground. The transducer's centerline should be in line with the bottom of the hull. Don't
let the bracket extend below the hull!

Mark the center of each slot for the mounting screw pilot holes. You
will drill one hole in the center of each slot.
Drill the holes. For the one-piece bracket, use the #29 bit (for the #10
screws). For the two-piece bracket, use the #20 bit (for the #12 screws).
5. Attaching transducer to transom.
Both bracket types: Attach the transducer to the transom. Slide the
transducer up or down until it's aligned properly with the bottom of
the hull as shown in the preceding and following figures. Tighten the
bracket's mounting screws, sealing them with the sealant.
Adjust the transducer so that it's parallel to the ground even if you
have a Deep-"vee" hull. Tighten the nut until it touches the outer
washer, then add 1/4 turn. Don't over tighten the lock nut! If you do,
the transducer won't "kick-up" if it strikes an object in the water.
Align transducer centerline with hull bottom and attach transducer to
transom. Rear view of dual-frequency Skimmer shown.
6. Route the transducer cable through or over the transom to the sonar
unit. Make sure to leave some slack in the cable at the transducer.

If possible, route the transducer cable away from other wiring on the
boat. Use caution when routing the transducer cable around these
wires.
WARNING:
Clamp the transducer cable to the transom close to the
transducer. This can prevent the transducer from entering the boat if it is knocked off at high speed.
Caution:
If you need to drill a hole in the transom to pass the connector
through, the required hole size be 1". If you drill the hole, make
sure it is located above the waterline. After installation, be sure
to seal the hole with the same marine grade above- or belowwaterline sealant used for the mounting screws.
7. Make a test run to determine the results. If the bottom is lost at
high speed, or if noise appears on the display, try sliding the transducer bracket down. This puts the transducer deeper into the water,
hopefully below the turbulence causing the noise. Don't allow the
transducer bracket to go below the bottom of the hull!
Trolling Motor Bracket Installation
(single-frequency only)
1. Attach the optional TMB-S bracket to the transducer as shown in the
following figure, using the hardware supplied with the transducer.
(Note: The internal tooth washer is supplied with the TMB-S.)
2. Slide the adjustable strap supplied with the TMB-S through the slot
in the transducer bracket and wrap it around the trolling motor. Position the transducer to aim straight down when the motor is in the
water. Tighten the strap securely.
15
Attach motor mounting bracket to transducer.
3. Route the transducer cable alongside the trolling motor shaft. Use
plastic ties (not included) to attach the transducer cable to the trolling motor shaft. Make sure there is enough slack in the cable for the
motor to turn freely. Route the cable to the sonar unit and the transducer is ready for use.

Transducer Orientation and Fish Arches
If you do not get good fish arches on your display, it could be because
the transducer is not parallel with the ground when the boat is at rest
in the water or at slow trolling speeds.

Transducer angles and their effects on fish arches.
If the arch slopes up – but not back down – then the front of the transducer is too high and needs to be lowered. If only the back half of the
arch is printed, then the nose of the transducer is angled too far down
and needs to be raised.
NOTE:
Periodically wash the transducer's face with soap and water to remove
any oil film. Oil and dirt on the face will reduce the sensitivity or may
even prevent operation.

Speed/Temperature Sensors
The FishEasy 350C can use two temperature sensors at the same time. It
also can use a speed sensor, but not at the same time as you are using a
secondary temp sensor. To use a speed sensor and a secondary temperature sensor at the same time, you will need a combination device.
NOTE:
If a second temp sensor is used, it must be the model TS-2U.

Speed Sensor Installation
The following instructions describe how to install the speed sensor.
Recommended tools include: drill, 5/8" drill bit, 1/8" drill bit for pilot holes,
screwdriver.
Required supplies include: four #8 stainless steel wood screws (3/4" long),
high quality, marine grade above- or below-waterline caulking compound.
(If you intend to route the sensor cable through the same hole as the
transducer cable, you will need a 1" (25.4 mm) drill bit instead of the 5/8"
drill bit.)
To install speed sensor:
1. Find a location on the boat's transom where the water flow is smooth-
est. Don't mount the sensor behind strakes or ribs. These will disturb the

water flow to the speed sensor. Make sure the sensor will remain in the
water when the boat is on plane. Also make sure the location doesn't interfere with the boat's trailer. Typically, the sensor is mounted about one foot
to the side of the transom's centerline.
2. Place the sensor on the transom. The bottom of the bracket should be
flush with the hull's bottom. Using the sensor as a template, mark the
hull for the screws' pilot holes. Drill four 1/8" holes, one in each end of
the slots.
3. Mount the sensor to the hull using #8 stainless steel wood screws
(not included). Use a high quality, marine grade above- or belowwaterline caulking compound to seal the screws. Make sure the sensor is
flush with the bottom of the hull and tighten the screws.

4. If the base of the transom has a radius, fill the gap between the tran-
som and the sensor with the caulking compound. This will help ensure
a smooth water flow.
5. Route the sensor's cable through or over the transom to the sonar
unit. If you need to drill a hole in the transom to pass the connector
through, the required hole size is 5/8". (The hole is 1" (25.4 mm) if you
intend to route the sensor cable through the same hole as the transducer
cable.)
Caution:
If you drill a hole in the transom for the cable, make sure it is
located above the waterline. After installation, be sure to seal the
hole with the same marine grade above- or below-waterline sealant used for the screws.
The sensor is now ready for use. Connect the sensor to the accessory
socket on the back of the unit. If you have any questions concerning the
installation of the sensor contact your local boat dealer.
Power Connections
The unit works from a 12-volt battery system. You can attach the
power cable to your boat's accessory or power buss or directly to the
battery. If you use an accessory buss but have problems with electrical
interference, attach the power cable directly to the battery. If the cable
is not long enough, splice #18 gauge wire onto it.
CAUTION:
When using
the unit in a saltwater environment, we strongly recommend that you shut off the power supply to the power cable
when the unit is not in use. When the unit is turned off but still
connected to a power supply, electrolysis can occur in the power cable plug. This may result in corrosion of the plug body along with
the electrical contacts in the cable and the unit's power socket.
In saltwater environments we recommend you connect the power
cable to the auxiliary power switch included in most boat designs.
23
If that results in electrical interference, or if such a switch is not
available, we recommend connecting direct to the battery and installing an inline switch. This will let you shut off power to the
power cable when the unit is not in use. When you are not using
the unit, you should always shut off power to the power cable, especially when the power cable is disconnected from the unit.
Power and transducer connections for the FishEasy 350C sonar
unit (direct battery connection shown).
If possible, keep the power cable away from other boat wiring, especially the engine's wires. This will provide the best isolation from electrical noise. The power cable has two wires, red and black. Red is the
positive lead, black is negative or ground. Make sure to attach the inline fuse holder to the red lead as close to the power source as possible.
CAUTION:
Do not use this product without a 3-amp fuse wired into the
power cable! Failure to use a 3-amp fuse will void your warranty. For corrosion protection in saltwater or high humidity
environments, apply a thin layer of electrical-grade grease to
each end of the fuse before installing it in the fuse holder.

Bracket Installation
Recommended tools include: drill, 1" (25.4 mm) drill bit, screwdriver.
Required supplies include: high quality, marine grade above- or belowwaterline caulking compound, three #10 stainless steel screws. Screw
length and type should be suitable for the material on which you intend to
mount the bracket.
Installing the bracket:
1. Mount the unit in any convenient location. Make sure there is
enough clearance for it to be tilted at angles. You should also make
sure there is enough room behind the unit to attach the
power/transducer cable.
NOTE:
Holes in the bracket’s base allow wood screw or through-bolt
mounting. You may need to place a piece of plywood on the back
side of thin panels to reinforce the panel and secure the mounting
hardware.
2. Drill a 1" (25.4 mm) hole in the dash for the power/transducer and
accessory cables. The best location for this hole is directly under the
gimbal bracket location.
3. Pass the connectors up through the hole from under the dash. You
can fill in the space around the cable with a marine caulking compound
or purchase a cable hole cover from a marine dealer.
Using the Quick Release Mounting Bracket
These units use a quick release mounting bracket. When you run the
cables through the bracket's cable slots, make sure you allow enough
slack for tilting the unit and attaching the connector.
1. Align the bracket over the cable hole with the cable slots facing away
from you and fit the cable through one of the slots. Fasten the bracket
to the dash using the three screw holes.

Portable Sonar Installation
Like many Eagle products, the FishEasy 3
50C sonar is capable of port-
able
operation. It uses the optional PPP-12 portable power pack.
The power pack and portable transducers expand the uses for your sonar. The PPP-12 package includes the power pack, battery adapter and a
portable transducer. The transducer can be stored inside the power pack.
The PPP-12 requires eight AA alkaline batteries. Batteries are not included.
To use a portable power pack, install the batteries and then attach the
sonar unit to the power pack's bracket. Plug in the power/transducer
cable to complete the installation. The PPP-12 has a quick-release
mounting bracket built into the case.
Installing the Batteries
Release the latch on the front of the power pack case. Open the compartment and install eight AA batteries into the adapter.
After installing the batteries, close the case and plug the sonar unit's
power cable into the socket on the power pack case.

Caution:
In cold weather the efficiency of dry cell batteries drops with the
temperature. It is a good idea to make sure the batteries are
warm before leaving home.
If the batteries do lose charge, sometimes they can be restored by placing them in a warm room or car interior.
WARNING:
Never heat the batteries over an open flame or direct
hot air onto them. A fire or explosion could result.
Portable Transducer Assembly
Recommended tools for installation include a slotted screw driver and
two adjustable wrenches.
1. Assemble the transducer and bracket as shown in the following figure. Attach the transducer to the bracket with the supplied hardware.
2. Make sure there is one washer on each side of the transducer, inside
the bracket. Slide the other washer over the end of the bolt and thread
the nut onto it.
3. Screw the suction cup onto the bracket using the supplied screw and
flat washer. Tie the nylon cord through the hole in the top of the bracket.
When using this transducer, tie the other end of the nylon cord to the
boat. This will help prevent the loss of the transducer if it comes off the
boat.
4. Clean the chosen area of the hull before attaching the suction cup.
Locate the transducer on the hull as shown in the following figure.
Don't allow the bracket to extend below the hull, because water pressure against it can cause the suction cup to come off at speed.
