Installation Guide
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
∆
Drill a corner hole away from the main cut line using a drill bit that will create a hole as close
to a diameter of .42 inches (10.7 mm) as possible. Repeat for the other three corners as
indicated 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.

Install the Control Head
1.
Clean the Mating Surfaces:
Use rubbing alcohol to clean the edges of the in-dash mounting
hole and the back rim of the control head where the gasket will be installed (see the illustration
Installing the Gasket
). Allow the cleaned areas to dry completely.
2. Place the control head, with the screen facing down, on a towel or cloth on a stable and level
surface.
3. Peel the brown liner from the adhesive backing on the gasket.
4. Hold the sides of the plastic film attached to the gasket with the adhesive side facing down (see
the illustration
Installing the Gasket
). Carefully align the gasket around the rim of the control
head so it is centered. Confirm there are no uneven gaps.
CAUTION!
Use caution when handling the gasket. Do not allow the adhesive to touch the sides
or rear of the control head during installation.
5.
Lightly press one side of the gasket
down onto the flat rim of the control head.
6. Confirm the alignment has not changed and that the gasket is centered around the control head.
Then lightly press down on the remaining sides of the gasket. Make adjustments, as needed.
7. Carefully peel the plastic film from the gasket.
8. Insert the control head through the mounting hole from the front side of the dash.
Press down
firmly around the sides of the control head for 20 seconds to secure the adhesive.

Route and Connect the Cables
1. See the installation guides included with each hardware component to install power and other
optional equipment.
2. Route all cables (power, transducer, accessories) to the control head and insert the connectors
into the correct ports on the back of the control head (see the illustration
Connecting the Cables
and
Control Head Ports
).
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.
Your control head is ready for on-the-water operation. See your control head operations manual for
further details.
Installing the Gasket
Install the gasket along the
flat rim of the control head
(highlighted in grey).
Confirm the gasket is evenly centered
around the rim of the control head.
