Cutting the Instrument Panel
Preparing the Mounting Location
1. Select a suitable location for the VesselView on the boat's instrument panel.
NOTE: The area behind the panel should be clear of any cables, wiring, or other hardware that may interfere with
installation. The mounting location should also provide good visibility from the boat operator's position.
2. Disconnect the batteries powering the gauges or SmartCraft components.
3. Cut out the supplied template.
NOTE: Always check the template cutout to the mounting holes on the VesselView before drilling.
4. Use the template to determine the space required for mounting.
5. Prepare the mounting location surface as follows:
•Fiberglass panels: Apply masking tape to the area being cut to prevent cracking the fiberglass.

•Vinyl‑covered panels: Use a razor blade to carefully remove the vinyl from the area being cut to avoid tearing the
vinyl.
Cutting the Panel
1. After preparing the area to be cut, tape the mounting template to the panel.
2. Use appropriate tools to cut out the shaded portion of the template. The mounting screw holes should be drilled using a 3
mm (1/8 in.) bit.
NOTE: The following diagram is an example only. Use the template that came with the kit.

2. Secure the VesselView with the appropriate size mounting screws. Use the supplied alignment tool when driving the
mounting screws, this will properly align the screws to ensure that the bezel will seat securely to the unit. Do not
overtighten the screws.
a - Maximum of 5.5 mm (0.22 in.)
b - Maximum of 2.2 mm (0.09 in.)
c - Use a screwdriver
d - Proper screw seating
e - No use of power drivers
f - Improper mounting hardware
3. Installing the bezel and removal: When fitting bezels, ensure that the hook tabs on the back of each bezel recess into
opposing slots on the screen frame. Once flush with the front surface of the screen, slide the top bezel to the left, and the
bottom bezel to the right to lock them into place. The bezel trim has been designed to be low profile, and therefore fully
conceal the locking tabs that keep it from being accidentally disengaged from the mounting flange. To remove the bezel
trim, slide it sideways; to the right for the top bezel and to the left for the bottom bezel.

DTS Wiring Guidelines
! WARNING
Splicing or probing will damage the wire insulation allowing water to enter the wiring. Water intrusion may lead to wiring
failure and loss of throttle and shift control. To avoid the possibility of serious injury or death from loss of boat control, do
not splice or probe into any wire insulation of the DTS system.
• Never attempt to connect, network, tie into, switch, sink source voltage or current from the DTS wiring harnesses.

• Never attempt to connect any type of communication or navigation equipment into the DTS wiring harnessing other than
at the designated connection point.
• Always install boat accessory equipment using an appropriate power source connection, such as a fuse panel or junction
box.
• Never attempt to tap directly into any of the DTS electrical wiring harnesses for a source of power.
Wiring Guidelines for Electrical Boat Accessories
! WARNING
Excessive voltage drop may compromise the DTS system, leading to serious injury or death from loss of throttle and shift
control. Do not wire any electrical accessory into the 12‑volt ignition key switch circuits of the DTS system.
IMPORTANT: Do not connect boat accessories to the ignition key switch. Use a separate, switched 12‑volt source for wiring
boat accessories.
IMPORTANT: The DTS system requires a consistent 12‑volt power source. Splicing or connecting accessories to the 12‑volt
or ignition key switch DTS circuits (purple, purple/white, or red wires) could blow a fuse or overload circuits, causing
intermittent or complete loss of operation.
Harness Installation Guidelines
• Locate an appropriate path for routing the harness connections to their installation points.
• Inspect the routing path to ensure that surfaces are free of any sharp edges or burrs that could cut the harness.
• Fasten and support the harness with clamps or cable ties every 45.8 cm (18 in.) along the routing path. A clamp or cable
tie must be used within 25.4 cm (10 in.) of any connection in a DTS system.
• Ensure that all connections are tight. Seal all unused connectors with weather caps.

VesselView 703 Connections
IMPORTANT: When replacing a VesselView 702 with a VesselView 703, it is important to know that the 703 has built‑in sonar
and wifi capabilities. If you are upgrading to VesselView 703 from a VesselView 702 display that used an external WIFI‑1
module and/or an external sonar module, it is recommended to use the capability of the 703 and no longer use the external
modules.
