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.
NOTE: Ensure the mounting surface is completely flat. Make adjustments to the mounting surface if fastening in place
puts the VesselView under tension.
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. Drill four pilot holes at the locations shown on the template for the mounting screws. Pilot hole sizes vary based on
instrument panel construction material. Follow the specifications in the table below.
Material
Soft materials—plywood 1.9–2.2 mm (5/64 in.)
Hard material—fiberglass, acrylic, hardwoods 2.3–2.6 mm (3/32 in.)
3. Use an appropriate tool to cut four 25 mm (1.0 in.) pilot holes at the locations shown on the template.
4. Use an appropriate saw to cut out the remaining shaded portion of the template.
