Engine fluids — oil pressure and coolant temp
Track oil pressure and coolant temperature — live from the engine ECU, or entered by hand.
With a Wi-Fi gateway on the boat's NMEA 2000 network, oil pressure, coolant temperature, oil temperature and fuel rate read live from the engine ECU. Without one, the per-engine coolant and oil tiles on Mission Control hold readings you enter by hand from your helm gauges.
A persistent low-oil-pressure reading should be treated as urgent — slow down, investigate, and consider shutting down even if the cause might just be a stuck sender.
Steps
-
Log readings today
Read coolant temperature and oil temperature off your helm gauges. In the Live telemetry section on Mission Control, tap Edit values and fill in the Coolant (°F) and Oil (°F) rows under Engines — one pair per main engine. There is no oil-pressure field to type into.
-
Watch the trend
Open a tile's history. Coolant that runs a few degrees hotter each week at the same load points at a raw-water problem before it becomes an alarm.
-
Set engine alerts
Menu (☰) → Settings → Vessel Setup → Engine Alerts. Set warn and urgent temperatures per engine. An alert trips when you save a reading past the threshold.

Live now — with a bridge installed
Oil pressure, coolant temperature and fuel rate arrive from the engine ECU via a Wi-Fi gateway, decoded from PGN 127489.
This needs a NMEA bridge (a Wi-Fi gateway) physically installed on the boat's NMEA 2000 network. Without one there is nothing to read and entry stays by hand.
