The color display has been specifically chosen to be viewable while wearing polarized sunglasses and emits light at an intensity of 750 Nit units.
The display has soft-key legends across the bottom that correspond to five actual buttons below the display area (which are somewhat difficult to see in the illustration above). Having five buttons for user input often enables simpler operation because each button can have a single function, but with new soft-key legends, each button can have a different function on different pages. As shown above the five button functions are (left to right) MODE (showing a hand for hand throttle control is selected; a foot is shown for foot throttle is selected), BOAT, HOME 1 (the current display), ENGINE, BACKLIGHT.
The NAUTILUS 3.5C has multiple screens including:
- ENGINE information page
- BOAT information pages
- MODE selection page
- HOME page
- SETTINGS page
- BACKLIGHT page
The ENGINE page monitors of the status of an Evinrude E-TEC G2 outboard and will also show status and warning messages. There are two preconfigured pages:
ENGINE1 shows
- • Engine Water Temperature
• Fuel Economy
• Engine Operating Hours
• Water Pressure (if available)
• Throttle Position
• Battery Voltage
ENGINE2 shows active system faults in a text box and advice messages.
The BOAT page displays fluid levels, fuel management, and trip log information. There are three preconfigured pages:
BOAT1 shows
- • Fuel Level - Tank 1 (instance 4)
• Fuel Level - Tank 2 (instance 5)
• Engine Onboard Oil Level (instance 0 or 1 depending on gauge configuration.
• Auxiliary Oil Level (default for instance 6)
BOAT2 shows
- • Fuel Economy
• Engine Trim Position
• Speed Over Ground (only available if a GPS device is present)
• Fuel Consumption
• Throttle Position
• Range – uses sum of fuel tank levels and average fuel economy value
• Fuel Remaining – sum of all fuel tanks
BOAT3 shows data shown for Trip 1 and Trip 2:
- • Distance
• Run Time
• Fuel Consumed (cumulative from all fuel tanks)
The MODE selection page allows adjustment of power steering boast, setting of trim assist ON-OFF, initiating winterization, and selection of throttle (if a foot throttle is installed).
The HOME page shows general cruising and performance information. There are three pages.
HOME1 shows
- • Speed Over Ground (only available if a GPS device is present)
• Engine RPM
• Gear Position
• Engine Trim Position
• Fuel Level (sum of total fuel sources)
HOME2 shows
- • Speed Over Ground (only available if a GPS device is present)
• Engine RPM
• Gear Position
• Fuel Level (sum of total fuel sources)
• Engine Trim Position
• Fuel Flow
HOME3 shows
- • Speed Over Ground (only available if a GPS device is present)
• Engine RPM
• Gear Position
• Engine Trim Position
• Water Pressure or Engine Coolant Temperature
The SETTINGS page is accessed by pushing and HOLDING the BACKLIGHT button. The SETTINGS page is used to set Configuration options, Calibration options, reset the trip log, restore the display to factory default settings, and view Firmware Information. There are extensive sub-pages and options available. A short push of the BACKLIGHT button switches the display to the BACKLIGHT page where backlight intensity can be set.
The NAUTILUS user interface can be configured in for use in English, French, Spanish and German languages. Units can be selected in imperial, metric and nautical measurements.
The NAUTILUS display is designed for use with one engine, but the display can be configured to match the INSTANCE setting of a particular engine, thus allowing perhaps two NAUTILUS displays (one configured for INSTANCE=0 and another configured for INSTANCE=1) to be useful with twin engines. (This may be expanded to four INSTANCE settings with the revision in April 2020.)
The NAUTILUS 3.5C display connects to a short wiring harness with a large multi-pin connector for the NAUTILUS and a break out into three connectors for interfacing:
- a DeviceNET Micro C plug for attachment to a NMEA-2000 network
- a two-pole Deutsch-type plug labeled "ACCESSORY POWER" to provide power for the display
- a two-pole Deutsch-type jack labeled "WARNING HORN" for connection to an aural alert sounder
The NATUILUS 3.5C gauges is also referred to in some literature as the ICON II 3.5C Round display.
The firmware of the device can be updated by use of a USB port on the rear panel.
The gauge needs a hole cut to 3-3/8-inch diameter (8.572-cm) for mounting. Minimum spacing to an adjacent similar size gauge is 4-inch on-center. The NAUTILUS gauge needs a minimum of 3-3/8-inch clear space behind the panel.
