3/8" drill bit, cutting tool for cutting the dashboard material, safety glasses and dust mask, and masking
tape.

NOTE: The illustrations in this manual may not look the same as your product, but your unit will function in the same way.
1. Plan the Mounting Location
Start by locating a suitable, flat area of the dashboard for mounting. Consider the following to find the best
mounting location:
532463-1_B
• Stability: The mounting area should be protected from waves, shock, vibration, and water.
• Depth: The control head requires a depth of at least 3 inches (76 mm).
• Accessibility: The location should be easily accessible for all cables to reach the ports on the back of
the control head.
NOTE: If a cable is too short for your application, extension cables are available. For assistance, contact Humminbird
Customer Service.
2. Cut the In-Dash Mounting Hole
To in-dash mount the PiranhaMAX control head, start by placing the components on the surfaces where you
intend to install them.
1. Review the instructions, measurements, and cutting options indicated on the In-Dash Mounting
Template.
2. Tape the template to the chosen in-dash mounting location.
3. Using the template, select the cutting method that is best for your boat:
• Drill one entry hole away from the main cut line that is large enough to insert the blade of your
cutting tool.
OR
• Using a 3/8" drill bit, drill the 4 corner holes (inside the main cut line) as shown on the template.
Use one of the corner holes as an entry hole, or drill an additional entry hole away from the main
cut line.
4. Carefully begin cutting toward the cut line, and continue cutting to the inside of the line around the
template.

5. Test the Mounting Hole: Install the control head in the mounting hole to test the fit. Make adjustments
to the mounting hole as needed. Remove the template when finished.
6. Thoroughly clean and deburr the mounting hole.
3. Install the Control Head
1. Insert and tighten the two threaded rods into the two threaded inserts located on the back side of the
control head. See the illustration Inserting the Threaded Rods.
2. From the front side of the dashboard, insert the control head through the mounting hole.
3. Press down lightly on the control head. Confirm the control head is centered and flush against the
dashboard. Make adjustments as needed.
4. From the back side of the dashboard, slide the bracket holes over the threaded rods. Install a nut onto
each threaded rod and hand-tighten until it is fully secure. Hand-tighten only! See the illustration
Assembling the Bracket.
5. Insert the cables into the ports on the back of the control head. The ports are keyed to prevent reverse
installation, so be careful not to force the connectors into the wrong port.

CAUTION! Do NOT mount the cables where the connectors could be submerged in water or flooded. If cables
are installed in a splash-prone area, it may be helpful to apply dielectric grease to the inside of the connectors to
prevent corrosion. Dielectric grease can be purchased separately from a general hardware or automotive store.
