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:
• install the control head
• install the transducer
• test the complete installation and lock the transducer position.
If you 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.
Supplies: 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.

Installation Overview
Fixed Control Head Installation
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 the installation section for
your transducer type in order to plan the
location of the transducer.
• The mounting surface should be stable
Figure 1
Figure 2
Connect the Power Cable to the Boat
A 6' long power cable is included to supply power to the control head. You
may shortenor 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.
enough to protect the control head from
excessive wave shock and vibration, and
should provide visibility while in operation.
• Your PiranhaMAX uses a tilt mounting base.
The mounting area should allow sufficient
room for the unit to pivot freely, and for easy
removal and installation (Figures 1 and 2).
NOTE: Make sure that the power cable is not connected to the control head at
the beginning of this procedure.

control head must have adequate protection through the proper selection and
installation of a 1 amp fuse.
1a. If a fuse terminal is available, use
crimp-on type electrical connectors
(not included) that match the
terminal on the fuse panel. Attach the
black wire to ground (-), and the red
wire to positive (+) 12 VDC power
(Figure 3). Install a 1 amp fuse (not
included) for protection of the unit.

4. Proceed to Route the Control Head
Cables Under the Deck.
Figure 5
Route the Control Head Cables Under the Deck
Use the following steps to route the control head cables under the deck.
NOTE: Under the deck cable routing is not always possible. If this is not an option,
the cables should be routed and secured above deck.
NOTE: See the installation section for your transducer type in order to plan the
location of the transducer and cable route.
1a. Mark and drill a 3/4" hole as shown in Figure 5. Route the cables
through the hole. The cables will exit through the center hole on the
control head base.
1b. If the cables cannot be routed directly beneath the control head base,
mark and drill a 3/4" hole that will allow you to run the cables close to
the control head base.

make sure there is enough cable slack for the unit to move freely. Hand
tighten the thumbknob bolt when you achieve the desired position for
the control head.
You are nowready to install the transducer. Proceed to Transducer Installation
Overview.
Transducer Installation Overview
The transducer can be installed on the transom of the boat, inside the hull, or
onto a trolling motor, depending on your transducer type. The type of
transducer you have will also determine how the cable will be routed. Go to
the section that describes your transducer, and follow the steps to position
and mount the transducer on your boat.
Due to the wide variety of hulls, only general instructions are presented in
NOTE:
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.
Transducer Installation Overview

Transom Transducer Installation
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: If you cannotfind 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 Customer Service at 1-800-633-1468.
Determine the Transducer Mounting Position
Turbulence: You must first determine the best locationon 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
rivets strakes
transom hull
Figure 8
Stepped Hull
step
Figure 9
• As theboat movesthrough 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 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 10).
The best way to locate turbulence-free water is
•
to view the transom while the boat is moving.This
methodis recommended if maximumhigh-speed
operation is a high priority. If this is not possible,
select a location on the transom where the hull
forward of this locationis smooth, flat and free of
protrusions or ribs (Figure 8).

Transom Transducer Installation
• On boats with stepped hulls, it may be possible to mount the transducer
15”
on the step. Do not mount the transducer on the transom behind a step to
avoid popping the transducer out of the water at higher speeds. Thetransducer must remain in the water for the control head to maintain the sonar
signal (Figure 9).
• 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.

and not in line with trailer bunks or rollers. (Figure 10).
NOTE: The hydrodynamic shape of your transducer allows it to point straight down
without deadrise adjustment (Figure 11).
Figure 11
NOTE: If you cannot find a transom mount location that will work for your
high-speed application, visit the FAQ (Frequently Asked Questions) section of our
Web site at humminbird.com or call Customer Service at 1-800-633-1468.

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.

2. Holdthe mountingbracket against the transom
of the boat in the location you have selected
(Figure 12).Align the bracket horizontally, using
the level. Make sure that the lower screw hole
protrusion does not protrude past thebottom 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 13).
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 bottomleft corner of themounting bracket with
the bottom of the boat.
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 eachslot, making
sure that your mark is centered in the slot
(Figure 14).

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. Usinga 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.
Assemble the Transducer and Initial Mounting
In this procedure, you will assemble the transducer using the hardwareprovided,
thenmount it and make adjustments to its position without locking it in place.
NOTE: You will initiallyassemble the transducer and the mounting bracket by matching
thetworatchetsto a numberedpositionon 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 15). 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.
or...
1b. If you do not know your transom angle,
measure it using a plumb line (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
16). Using a ruler, measure the distance
from the bottom of the plumb line to
the back of the transom, then use the
chart (Figure 15).

NOTE: It is important to take your measurement in the location shown in
Figure 16, 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 17a). 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 17b).
NOTE: The ratchets are keyed. Make sure that the square teeth on each
ratchet face the square teeth on the transducer knuckle, and the triangular
teeth face outward.
Hold the ratchets on the transducer knuckle with one hand and fit the
mounting bracket overthem until it snaps into place with the other hand. Refer
to the illustration (Figure 17d).

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 22).
NOTE: The transducer has a natural downward
slantof 4-5degrees fromleading 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.
7. Continue to adjust until the bracket is also
level from port to starboard (horizontally
level as you look at the transducer from
behind the boat [Figure 23]).
8. Mark the correct position on the transom by
