Installation Overview
Before you start installation, we encourage you to read these instructions
carefully in order to get the full benefit from your PiranhaMAX.
There are three basic installation tasks that you must perform for the
PiranhaMAX:
• Installing the Control Head
• Installing the Transducer
• Testing the complete installation and locking the transducer position.
NOTE: In addition to the hardware supplied with your transducer, you will need a
powered hand drill and various drill bits, various hand tools, including a ruler or
straightedge, a level, a 12" plumb line (weighted string or monofilament line), marker or
pencil, safety glasses and dust mask, and marine-grade silicone sealant.
NOTE: If you have purchased a PiranhaMAX Portable unit, proceed to
PiranhaMAX Portable Case Assembly for installation instructions. If you are
planning a fixed installation, proceed to Fixed Control Head Installation.

Fixed Control Head Installation
1. Determine Where to Mount
Begin the installation by determining where to mount the control head.
Consider the following to determine the best location:
• To check the location planned for the control
head, test run the cables for the power and
transducer. See Transom Transducer Installation
in order to plan the location of the transducer
and cable route.
• The mounting surface should be stable enough
Figure 1
to protect the control head from excessive wave
shock and vibration, and should provide visibility
while in operation.
• Your PiranhaMAX uses a tilt and swivel
mounting base. The mounting area should allow
sufficient room for the unit to pivot and swivel
freely, and for easy removal and installation
Figure 2
(Figures 1 and 2).
2. Connect the Power Cable to the Boat
A 6' long power cable is included to supply power to the control head. You may
shorten or lengthen the cable using 18 gauge multi-stranded copper wire.
CAUTION! Some boats have 24 or 36 Volt electric systems, but the control head MUST
be connected to a 12 VDC power supply.
The control head power cable can be connected to the electrical system of the
boat at two places: a fuse panel usually located near the console, or directly to
the battery.
NOTE: Make sure that the power cable is not connected to the control head at the
beginning of this procedure.

Transom Transducer Installation Overview
Following are instructions for transom mount installation. The transom mount
installation provides the least loss of signal since the transducer is mounted
outside the hull. This installation also allows adjustment of both running angle
and depth after the transducer is mounted, which enables you to tune the
installation for best results.
NOTE: Due to the wide variety of hulls, only general instructions are presented in
this installation guide. Each boat hull represents a unique set of requirements that
should be evaluated prior to installation. It is important to read the instructions
completely and understand the mounting guidelines before beginning installation.
NOTE: When drilling holes in fiberglass hulls, it is best to start with a smaller bit and use
progressively larger drill bits to reduce the chance of chipping or flaking the outer coating.
NOTE: If you cannot find a transom mount location that will work for your boat hull, a
different mounting technique or transducer type should be considered. See the FAQ
(Frequently Asked Questions) section of our Web site at humminbird.com or call our
Customer Resource Center at 1-800-633-1468 .

Transom Transducer Installation
1. Locate the Transducer Mounting Position
Turbulence: You must first determine the best location on the transom to
install the transducer. It is very important to locate the transducer in an area
that is relatively free of turbulent water.
Consider the following to find the best location with the least amount of
turbulence:
Areas of Possible Turbulence
• As the boat moves through the water,
turbulence is generated by the weight of the
boat and the thrust of the propeller(s) - either
clockwise or counter-clockwise. This turbulent
water is normally confined to areas
immediately aft of ribs, strakes or rows of
rivets on the bottom of the boat, and in the
immediate area of the propeller(s). Clockwise
Rivets
propellers create more turbulence on the port
side. On outboard or inboard/outboard boats,
it is best to locate the transducer at least 15"
to the side of the propeller(s) (Figure 11).
Hull
Transom
Strakes
Figure 9
Stepped Hull
• The best way to locate turbulence-free
water is to view the transom while the boat
is moving. This method is recommended if
maximum high-speed operation is a high
priority. If this is not possible, select a
location on the transom where the hull
forward of this location is smooth, flat and
free of protrusions or ribs (Figure 9).
Step
Rib
Figure 10
• On boats with stepped hulls, it may be
possible to mount the transducer on the
step. Do not mount the transducer on the
transom behind a step to avoid popping the

9
transducer out of the water at higher speeds. The transducer must
remain in the water for the control head to maintain the sonar signal
(Figure 10).
• If the transom is behind the propeller(s), it may be impossible to find an
area clear from turbulence, and a different mounting technique or
transducer type should be considered, such as an Inside the Hull
Transducer.
• If you plan to trailer your boat, do not mount the transducer too close
to trailer bunks or rollers to avoid moving or damaging the transducer
during loading and unloading of the boat.
• If high speed operation is critical, you may want to consider using an
In-Hull transducer instead of this Transom Mount transducer.
Level
15”
Deadrise Angle
Figure 12
Find a turbulence-free location at least 15” from the propeller(s)
and not in line with trailer bunks or rollers. (Figure 11).
NOTE: The hydrodynamic shape of your transducer allows it to point straight down
without deadrise adjustment (Figure 12).
NOTE: If you cannot find a transom mount location that will work for your
high-speed application, please visit the FAQ (Frequently Asked Questions) section
of our Web site at humminbird.com or call our Customer Resource Center at
1-800-633-1468.
2. Prepare the Mounting Location
After determining the mounting location for the transducer, follow the steps
below to position and mount the transducer bracket.

Positioning the Mounting Bracket
1. Make sure that the boat is level on the trailer, both
from port to starboard and from bow to stern, by
placing your level on the deck of the boat, first in
one direction, then in the other.
Level
2. Hold the mounting bracket against the transom of
the boat in the location you have selected (Figure
13). Align the bracket horizontally, using the level.
Make sure that the lower screw hole protrusion
does not protrude past the bottom of the hull, and
there is at least 1/4" clearance between the
bottom of the bracket and the bottom of the
transom for fiberglass boats, and 1/8" clearance
for aluminum boats (Figure 14).
Figure 13
Boat Hull Types Require
Different Mounting Positions
NOTE: If you have a flat-bottomed aluminum boat, some
additional adjustment may be needed to accommodate the
rivets on the bottom of the boat (i.e. the gap may need to be
a little smaller than 1/8"). This will help you to avoid excessive
turbulence at high speeds.
NOTE: If your propeller moves clockwise as the boat moves
forward (as you're facing the stern of the boat from behind),
mount the transducer on the starboard side, and align the
bottom right corner of the mounting bracket with the bottom
of the boat. If your propeller moves counterclockwise as the
boat moves forward (as you're facing the stern of the boat
from behind), mount the transducer on the port side, and align
the bottom left corner of the mounting bracket with the
bottom of the boat.

Using the Mounting Bracket to
Mark the Initial Drill Holes
3. Continue to hold the bracket on the transom of the
boat, and use a pencil or marker to mark where to
drill the two mounting holes. Mark the drill holes
near the top of each slot, making sure that your
mark is centered in the slot (Figure 15).

Drill Holes
NOTE: The third hole should not be drilled until the angle
and height of the transducer is finalized, which you will
not do until a later procedure.

4. Make sure that the drill bit is perpendicular to the actual surface of the
transom, NOT parallel to the ground, before you drill. Using a 5/32” bit,
drill the two holes only to a depth of approximately 1”.
NOTE: On fiberglass hulls, it is best to use progressively larger drill bits to reduce the
chance of chipping or flaking the outer coating.
3. Assemble and Mount the Transducer
In this procedure, you will assemble the transducer using the hardware
provided, then mount it and make adjustments to its position without locking
it in place.
NOTE: You will initially assemble the transducer and the mounting bracket by matching
the two ratchets to a numbered position on the transducer knuckle. Further adjustments
may be necessary.
1a. If you already know your transom angle, refer to the chart below for
the initial position to use to set the ratchets (Figure 16). If your transom
is angled at 14 degrees (a common transom angle for many boats) use
position 1 for the ratchets. In either case, go to step 2.

(weighted nylon string or monofilament line) exactly 12 inches long.
Hold the top of the plumb line against the top of the transom with your
finger, and wait until the line hangs straight down (Figure 17). Using a
ruler, measure the distance from the bottom of the plumb line to the
back of the transom, then use the chart (Figure 16).
NOTE: It is important to take your measurement in the location shown in Figure 17,
from exactly 12 inches down from the top of the transom.

2. Place the two ratchets, one on either side of
the transducer knuckle, so that the beads on
each ratchet line up with the desired position
number on the knuckle (Figure 18a). If you are
setting the ratchets at position 1, the beads
on each ratchet will line up with the rib on the
transducer knuckle to form one continuous
line on the assembly (Figure 18b).

6. Adjust the transducer assembly vertically,
until the seam on the leading edge of the
transducer (the edge closest to the transom of
the boat) is level and just slightly below the
hull (Figure 23).
NOTE: The transducer has a natural downward slant of 4-5
degrees from leading edge (closest to the boat transom) to
trailing edge (farthest away from the boat). Looking at the
back of the transducer, the seam should be slightly below
the bottom of the hull.

4. Route the Cable
The transducer cable has a low profile connector, which must be routed to the
point where the control head is mounted. There are several ways to route the
transducer cable to the area where the control head is installed. The most
common procedure routes the cable through the transom into the boat.
NOTE: Your boat may have a pre-existing wiring channel or conduit that you can use for
the transducer cable.
1. Unplug the other end of the transducer cable from the control head.
(The transducer cable was connected in the earlier section Attach the
Cables to the Control Head). Make sure that the cable is long enough
to accommodate the planned route by running the cable over the
transom.
CAUTION! Do not cut or shorten the transducer cable, and try not to damage the cable
insulation. Route the cable as far as possible from any VHF radio antenna cables or
tachometer cables to reduce the possibility of interference. If the cable is too short,
extension cables are available to extend the transducer cable up to a total of 50'. For
assistance, contact the Customer Resource Center at humminbird.com or call
1-800-633-1468 for more information.
NOTE: Allow enough slack in the cable for slight movement at the pivot point. It is best
to route the cable to the side of the transducer so the transducer will not damage the
cable during movement.
2a. If you are routing the cable over the transom of the boat, secure the
cable by attaching the cable clamp to the transom, drilling 9/64"
diameter holes for the #8 x 5/8" wood screws, then skip directly to step
5 to connect the cable.
or...
2b. If you will be routing the cable through a hole in the transom, drill a
5/8" diameter hole above the waterline. Route the cable through this
hole, then fill the hole with marine-grade silicone sealant and proceed
to the next step immediately.

3. Place the escutcheon plate over the cable
hole and use it as a guide to mark the two
escutcheon plate mounting holes. Remove
the plate, drill two 9/64" diameter x 5/8" deep
holes, and then fill both holes with marine-
grade silicone sealant. Place the escutcheon
plate over the cable hole and attach with two
#8 x 5/8" wood screws. Hand tighten only!
Routing the Cable
4. Route and secure the cable by attaching the
cable clamp to the transom. Drill one 9/64"
diameter x 5/8" deep hole, then fill hole with
marine-grade silicone sealant, then attach the
cable clamp using a #8 x 5/8" screw. Hand
tighten only!
NOTE: If there is excess cable that needs to be
gathered at one location (as shown in the illustration),
dress the cable routed from both directions so that a
single loop is left extending from the storage location.
Doubling the cable up from this point, form the cable
into a coil. Storing excess cable using this method can
reduce electronic interference (Figure 26).
Figure 25
Storing Excess Cable
5. Plug the cable connector back into the control
head. The slots are keyed to prevent reversed
installation, so be careful not to force the
connector into the holder.
Figure 26
Your control head is now ready for operation.

5. Test and Finish the Installation
Once you have installed both the control head and the transom transducer, and
have routed all the cables, you must perform a final test before locking the
transducer in place. Testing should be performed with the boat in the water.
1. Press POWER once to turn the control head on. If the unit does not
power up, make sure that the connector is fully plugged into the
terminal slot and that power is available.
2. If all connections are correct and power is available, the Humminbird®
control head will enter Normal operation.
3. If the bottom is visible on-screen with a digital depth readout, the unit
is working properly. Make sure that the boat is in water greater than
2' but less than the depth capability of the unit, and that the
transducer is fully submerged, since the sonar signal cannot pass
through air.
NOTE: The transducer must be submerged in water for reliable transducer detection.
4. If the unit is working properly, gradually increase the boat speed to
test high-speed performance. If the unit functions well at low speeds,
but begins to skip or miss the bottom at higher speeds, the transducer
requires adjustment.
5. If you have the correct angle set on the transducer, yet lose a bottom
reading at high speed, adjust the height and the running angle in
small increments to give you the ideal transducer position for your
boat. First, adjust the height in small increments (Figure 23).
NOTE: The deeper the transducer is in the water, the more likely that a rooster tail of
spray will be generated at high speeds, so make sure that the transducer is as high as it
can be and still be submerged in the water.
If you are still not getting good high speed readings, you may need to disassemble
the transducer mounting assembly and re-position the ratchets (Figures 18a - 18d).
If you do change the transducer position, re-trace the position of the mounting
bracket before proceeding.
Transom Transducer Installation
Download from Www.Somanuals.com. All Manuals Search And Download.
18
NOTE: It is often necessary to make several incremental transducer adjustments before
optimum high speed performance is achieved. Due to the wide variety of boat hulls,
however, it is not always possible to obtain high speed depth readings.
6. Once you have reached a consistently good sonar signal at the desired
speeds, you are ready to lock down the transducer settings. Remove
the transducer from the bracket (after noting where the ratchets are
assembled), then re-align the mounting bracket against the transom of
the boat to match the traced silhouette. Check the bracket position
with the level again to make sure it is still level, then mark the third
mounting hole using a pencil or marker. Unscrew and remove the
mounting screws and the transducer bracket and set aside.
7. Drill the third mounting hole, using a 5/32” drill bit. Use a marine-
grade silicone sealant to fill all three drilled mounting holes, especially
if the holes penetrated the transom wall.
NOTE: On fiberglass hulls, it is best to use progressively larger drill bits to reduce the
chance of chipping or flaking the outer coating.
Fully Tighten All Three
Mounting Screws
8. Re-position the transducer bracket against
the transom of the boat, then hand-install all
three screws. Make sure that the transducer
location has not changed, then fully tighten
all three mounting screws (Figure 27). Hand
tighten only! Re-install the transducer to the
mounting bracket, making sure to assemble
the ratchets in the same location they had
before. (See Figures 18a - 18d and Figure 21 -
22). If you have performed the preceding
Figure 27
procedures correctly, the transducer should
be level and at the right height for optimal
operation.

Mounting the Portable Transducer
Once your Portable fishfinder is fully assembled (see the Portable Case
Assembly section for more information), it takes just a few easy steps before
you are ready to fish:
• Test the transducer prior to installation
• Mount the portable transducer on the boat
1. Test the Transducer Prior to Installation
Prior to installation, test the transducer to make sure that no damage occurred
during shipping.
1. Hold the transducer in the water over the side of the boat to confirm
proper operation. If the transducer is working properly, you should be
able to see the bottom on the control head display.
2. Mount the Portable Transducer on the Boat
Perform the procedures in this section to install the transducer on your boat.
NOTE: The suction cup mount is designed for quick, easy installation and removal,
NOT for high speed operation. If you intend to operate your boat at any speed faster
than trolling speeds, remove the suction cup transducer from the water.
It is important that the mounting position allows the transducer to rest beneath
the surface of the water, pointing straight down. You can mount the transducer
anywhere on the side of the boat if your boat remains stationary. If you are
trolling, it is best to mount the transducer on the transom of the boat.
Your portable transducer is designed to be installed and adjusted without the
use of tools. Mounting the transducer to the boat is a simple yet important
operation. A poor mounting location will affect the overall performance of the
Humminbird® unit, so follow the mounting instructions carefully. It is important
that the mounting position allows the transducer to rest beneath the surface
of the water, pointing straight down. You can mount the transducer anywhere
on the side of the boat if your boat remains stationary.
Mounting the Portable Transducer

32
NOTE: If you are trolling, it is best to mount the transducer on the transom of the boat.
1. Mount the transducer so that it points straight down and so that the
transducer itself is submerged in the water (see the illustration
Portable Transducer Mount).
Portable Transducer Mount
Transducer Running Angle

2. Adjust the running angle so that the transducer is parallel to and
below the surface of the water (see the illustration Transducer
Running Angle).
3. Hand-tighten the wing nut so that the transducer will not rotate.
Transducer Tie-Down Strap
4. Secure the transducer cable in case of
accidental release when the boat is
moving, since a loose transducer can
cause damage to itself, your boat, or
become tangled in the propeller.
Attach the tie-down strap to the
transducer cable around an
immovable object such as a rail or
fitting, as shown in the illustration (see
Figure 45
the illustration Transducer Tie-Down
Strap).
5. When you have finished using the transducer, unplug the transducer
cable from the transducer jumper port on the base, then coil the cable
around the assembly.

PiranhaMAX Sonar Technology
The PiranhaMAX is the easiest to use fishfinder ever. For most anglers, all you’ll
ever need to do is power on and fish! The PiranhaMAX automatically
determines depth and makes adjustments to keep the bottom and fish visible
on the display.
The PiranhaMAX uses sonar technology to send sound waves from the
transducer into the water. The returned “echoes” are plotted on the display,
creating a very accurate picture of the underwater world, including distance to
underwater objects such as the bottom, fish, and structure.
Your PiranhaMAX will have Single or Dual Beam sonar. Find the correct sonar
description that applies to your unit.
PiranhaMAX Sonar Technology
Download from Www.Somanuals.com. All Manuals Search And Download.
36
Single Beam Sonar
The PiranhaMAX 165 uses a 200 kHz single beam sonar system with a 28°
area of coverage. Boat speed, wave action, bottom hardness, water conditions
and transducer installation can all affect depth capability.
Dual Beam Sonar
The PiranhaMAX 175, 176i, 195c, and 196ci use a 200/455 kHz dual beam
sonar system with a 28° area of coverage. Dual Beam sonar is optimized to
show the greatest bottom definition using a narrow (16°) beam yet can still
indicate fish found in the wide (28°) beam when the Fish ID+™ feature is
turned on. Dual Beam is ideal for a wide range of conditions - from shallow to
very deep water in both fresh and salt water. Boat speed, wave action, bottom
hardness, water conditions, and transducer installation can all affect depth
capability.

What You See on the Display
The PiranhaMAX displays underwater information in an easy-to-understand
format. The top of the display corresponds to the water surface at the
transducer, and the bottom of the display corresponds to the Depth Range
automatically selected for the current water depth. The Bottom Contour varies
as the depth under the boat changes. Digital readouts provide precise
information for depth, fish, and water temperature.
As the boat moves, terrain and bottom composition variations are displayed.
Fish, baitfish, and thermoclines (underwater temperature changes) are
displayed when detected. Underwater conditions vary greatly, so some
experience and interpretation is needed to realize all the benefits of the
PiranhaMAX - use the following illustrations as a guide to the most common
conditions and practice using your PiranhaMAX over known bottom types.

How GPS Works
If your PiranhaMAX model includes GPS (Global Positioning System), it will use
GPS and sonar to determine your current track, display it on a grid, and provide
detailed underwater information.
GPS uses a constellation of satellites that
continually send radio signals to the earth. The
GPS receiver on your boat receives signals from
satellites that are visible to it. Based on time
differences between each received signal, the
GPS receiver determines its distance to each
satellite. With distances known, the GPS receiver
mathematically triangulates its own position.
With 5 updates per second, the GPS receiver then
calculates its velocity and bearing.
GPS was originally intended for military use; however, civilians may also take
advantage of its highly accurate position capabilities, typically within +/- 4.5
meters, depending on conditions. This means that 95% of the time, the GPS
receiver will read a location within +/- 4.5 meters of your actual position. Your
GPS Receiver also uses information from WAAS (the Wide Area Augmentation
System), EGNOS (the European Geostationary Navigation Overlay Service), and
MSAS (the MTSAT Satellite Augmentation System) satellites if they are
available in your area.
PiranhaMAX models that include GPS currently support the following GPS
functionality:
• View current track (breadcrumb trail)
• View precision speed and heading
• Save waypoints. Your Fishfinder can store over 500 waypoints.
See Track View for more information.

Maintenance
Your Humminbird® fishfinder is designed to provide years of trouble free
operation with very little maintenance. Use the following procedures to ensure
your Humminbird® continues to deliver top performance.
Control Head Maintenance
It is important to consider the following precautions when using your
Humminbird® control head:
• Chemicals, such as those found in bug spray and sunscreen, may cause
permanent damage to the control head screen. Such damage is not
covered by the warranty.
• NEVER leave the control head in a closed car or trunk. The high
temperatures generated in hot weather can damage the electronics.
Use the following information to keep the control head and screen clean.
• Screen: To clean the control head screen, use a mild soap (such as a
non-abrasive liquid hand soap) and warm water. Wipe the screen dry
with a soft cloth. Be careful to avoid scratching the screen. If water
spots remain, use a solution of water and vinegar.
WARNING! Do not use a chemical glass cleaner on the screen. Chemicals in
the solution may cause cracking in the lens of the unit.
NOTE: Do not wipe the screen while dirt or grease is on the screen.
• Control Head: If the control head comes into contact with salt spray,
wipe the affected surfaces with a cloth dampened with fresh water.
Transducer Maintenance
Use the following information to maintain the transducer operation.
• If your boat remains in the water for long periods of time, algae and
other marine growth can reduce the effectiveness of the transducer.
Periodically clean the face of the transducer with liquid detergent.
NOTE: To clean the transducer, you may need to pivot the transducer up in the bracket.
Maintenance

62
• If your boat remains out of the water for a long period of time, it may
take some time to wet the transducer when it is returned to the water.
Small air bubbles can climb to the surface of the transducer and
interfere with proper operation. These bubbles dissipate with time, or
you can wipe the face of the transducer with your fingers after the
transducer is in the water.
PiranhaMAX Portable Case Maintenance
• If the portable case comes into contact with salt spray, wipe the
affected surfaces with a lint-free cloth, then apply a commercially
available anti-corrosive treatment to all exposed electrical contacts.
• If the portable case bag becomes dirty, clean the bag with mild soap,
water, and a soft rag or brush and then hang it up to dry.
How to Remove Water from the Portable Case
Open the front zipper and pull the case down to allow water to exit the case.
If needed, remove the case from the plastic base and air-dry it. Follow
recommended maintenance procedures for salt spray exposure if needed.

Troubleshooting
Do not attempt to repair the PiranhaMAX yourself. There are no user-serviceable parts
inside, and special tools and techniques are required for assembly to ensure the waterproof
integrity of the housing. Repairs should be performed only by authorized Humminbird®
technicians.
Many requests for repair received by Humminbird® involve units that do not actually need
repair. These units are returned “no problem found.” If you have a problem with your
PiranhaMAX, use the following troubleshooting guide before calling the Customer
Resource Center or sending your unit in for repair.
1. Nothing happens when I turn the unit on.
Check the power cable connection at both ends. Be sure the cable is connected
correctly to a reliable power source — red lead to positive, black lead to negative or
ground. Ensure the power available is between 10 and 20 VDC. If the unit is wired
through a fuse panel, ensure the panel is powered. Often accessory fuse panels are
controlled by a separate switch or the ignition switch.
Also, often a fuse can appear to be good when it is not. Check the fuse with a tester or
replace it with a fuse known to be good.
Check the power connection to the PiranhaMAX. It is possible to force the power cable
connector into the cable holder incorrectly. If the connector is reversed, the unit will not
work. Examine the contacts on the back of the unit to ensure there is no corrosion.
2. There is no transducer detected.
The PiranhaMAX has the ability to detect and identify that a transducer
is connected. When powering on, if a message indicates “transducer not connected”,
make sure that an appropriate transducer connector is plugged into the unit. In addition,
inspect the transducer cable from end to end for breaks, kinks, or cuts in the outer
casing of the cable. Also make sure that the transducer is fully submerged in water. If
the transducer is connected to the unit through a switch, temporarily connect it directly
to the unit and try again. If none of these actions identifies an obvious problem, the
transducer itself is probably at fault. Be sure to include the transducer if returning the
unit for repair.
3. There is no bottom reading visible on the display.
If the loss of bottom information occurs only at high boat speeds, the transducer needs
adjusting – see your PiranhaMAX Installation Guide for details. Also, in very deep water,
it may be necessary to increase the sensitivity setting manually to maintain a graphic
depiction of the bottom. If you are using a transducer switch to connect two transducers
to the PiranhaMAX, make sure that the switch is in the correct position to connect a
transducer that is in the water. (If a trolling motor transducer is selected and the trolling
motor is out of the water, no sonar information appears.) If none of these actions solves

temporarily connect it directly to the unit and try again. If none of these actions
identifies an obvious problem, the transducer itself may be at fault. Be sure to include
the transducer if returning the unit for repair.
4. When in very shallow water, I get gaps in the bottom reading and inconsistent
digital depth indication.
The PiranhaMAX will work reliably in water 3 feet (90 cm) or deeper. Remember that the
depth is measured from the transducer, not from the surface of the water.
5. The unit comes on before I press the POWER-MENU key, and won’t turn off.
Check the transducer cable — if the outer jacket of the cable has been cut and the
cable is in contact with bare metal, you will need to repair the cut with electrical tape.
If there is no problem with the cable, disconnect the transducer from the unit and see
if the problem is corrected, to confirm the source of the problem.
6. I get gaps in the reading at high speeds.
Your transducer needs adjusting. If the transducer is transom-mounted, there are two
adjustments available to you: height, and running angle. Make small adjustments and
run the boat at high speeds to determine the effect. It may take several tries to optimize
high-speed operation. This can also be a result of air or turbulence in the transducer
location caused by rivets, ribs, etc.
7. My unit loses power at high speeds.
Your PiranhaMAX has over-voltage protection that turns the unit off when input voltage
exceeds 20 VDC. Some outboard motors do not effectively regulate the power output of
the engine’s alternator and can produce voltage in excess of 20 Volts when running at
high RPMs.
8. The display begins to fade out. Images are not as sharp as normal.
Check the input voltage. The PiranhaMAX will not operate on input voltages below 10
VDC.
9. The display shows many black dots at high speeds and high sensitivity settings.
You are seeing noise or interference caused by one of several sources. Noise can be
caused by electronic devices. Turn off any nearby electronics and see if the problem
goes away. Noise can also be caused by the engine. If engine noise is causing the
interference, the problem will intensify at higher RPMs. Increase the engine speed with
the boat stationary to isolate this cause. Propeller cavitation can also appear as noise on
the display. If the transducer is mounted too close to the propeller, the turbulence
generated can interfere with the sonar signal. Make sure that the transducer is mounted
at least 15" (380 mm) from the propeller.
