Transducer Installation  
Preparations  
You can install the sonar in some other order if you prefer, but we rec-  
ommend this installation sequence:  
Caution:  
You should read over this entire installation section before drill-  
ing 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 so-  
nar/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, stain-  
less steel mounting bracket. The larger dual-frequency Skimmers typi-  
cally use a two-piece, plastic mounting bracket. The trolling motor  
mount uses a one-piece plastic bracket with an adjustable strap.

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 above-  
or below-waterline sealant/adhesive compound.  
Dual-frequency transom installations  
Tools: two adjustable wrenches, drill, #20 (0.161") drill bit, Phillips head screw-  
driver. 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.  
2
Download from Www.Somanuals.com. All Manuals Search And Download.  
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.  
CAUTION: Clamp the trans-  
ducer cable to transom near  
the transducer. This will help  
prevent 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.  
Transom  
Transducer  
centerline  
Hull bottom  
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 fre-  
quently lose bottom signal lock while running at high speed, the trans-  
ducer 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 instruc-  
tions 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.  
Dot  
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 plas-  
tic bracket and two on either side of the transducer as shown in the fol-  
lowing 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 pa-  
rallel 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 fig-  
ure. 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 transduc-  
er'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.

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 enter-  
ing 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 below-  
waterline 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 trans-  
ducer 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. Po-  
sition the transducer to aim straight down when the motor is in the  
water. Tighten the strap securely.

3. Route the transducer cable alongside the trolling motor shaft. Use  
plastic ties (not included) to attach the transducer cable to the trol-  
ling 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 trans-  
ducer 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.

If the arch slopes up – but not back down – then the front of the trans-  
ducer 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.

Power Connections (permanent mount only)  
The unit works from a 12-volt battery system. You can attach the pow-  
er cable to your boat's accessory or power buss (or directly to the bat-  
tery). 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 rec-  
ommend 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 ca-  
ble 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.  
If that results in electrical interference, or if such a switch is not  
available, we recommend connecting direct to the battery and in-  
stalling 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, es-  
pecially when the power cable is disconnected from the unit.  
If possible, keep the power cable away from other boat wiring, especial-  
ly 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 in-line fuse  
holder to the red lead as close to the power source as possible.

power buss. This will protect both the unit and the power cable in the  
event of a short. It uses a 3-amp fuse.  
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 warran-  
ty.  
This unit has reverse polarity protection. No damage will occur if the  
power wires are reversed. However, the unit will not work until the  
wires are attached correctly.  
Mounting the Sonar Unit: In-Dash, Bracket or Portable  
You can install the sonar unit on the top of a dash with the supplied  
bracket. This unit can be installed in a dash with the optional FM-6 in-  
dash adapter kit. The FM-6 kit includes an instruction sheet, part 988-  
0147-631, which contains a template for cutting out the mounting hole.

Bracket Installation  
Recommended tools for this job include: drill, 1" (25.4 mm) drill bit and  
a screwdriver. Required supplies for this job include: high quality, ma-  
rine grade above- or below-waterline 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.  
Mount the unit in any convenient location, provided there is clearance  
when it’s tilted for the best viewing angle. You should also make sure  
there is enough room behind the unit to attach the power/transducer  
cable. (See the following drawings, which show the dimensions of a  
gimbal-mounted X-4 sonar unit.)

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 pa-  
nels to reinforce the panel and secure the mounting hardware.  
Drill a 1" (25.4 mm) hole in the dash for the power/transducer and ac-  
cessory cables. The best location for this hole is immediately under the  
gimbal bracket location. This way, the bracket can be installed so that  
it covers the hole, holds the cables in position and results in a neat in-  
stallation. Some customers, however, prefer to mount the bracket to the  
side of the cable hole — it's a matter of personal preference.  
After drilling the hole, pass the connectors up through the hole from  
under the dash. If you wish, you can fill in the hole around the cable with  
a good marine caulking compound. (Some marine dealers stock cable hole  
covers to conceal the opening.)  
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. (The snug fit of  
the push-on waterproof connector requires some force to attach.)

chets and lift the unit off the bracket.  
Portable Sonar Installation  
Like many Lowrance products, the X-4 sonar is capable of portable op-  
eration. It uses the optional PPP-12 portable power pack.  
The PPP-12 package includes the power pack, battery adapter and a port-  
able transducer. The transducer can be stored inside the power pack. The  
PPP-12 requires eight AA alkaline batteries. Batteries are not included.  
17

To use a portable power pack, you install the batteries and then attach  
the sonar unit to the power pack's bracket. Plug in the pow-  
er/transducer cable and you're ready to fish.  
The PPP-12 has a quick-release mounting bracket built into the case.  
Installing the Batteries  
Open the case and lay it flat. (The latch is located below the handle.)  
Insert eight "AA" size batteries into the battery adapter and place it in  
the battery compartment. Slip the battery cover tabs into the slots in  
the case wall, then close the battery cover with the thumb screw.  
Plug the cable's power (dog bone-shaped) connector into the socket on  
the battery compartment cover. Route the cable's unit connector and  
about 6 inches (15.2 cm) of cable through the opening under the sonar  
mount. Close the case bottom, using the slot in the case wall to avoid  
pinching the cable. Turn the unit over to mount the sonar.
