Your engine is already talking. Start listening.

Every boat with NMEA 2000 broadcasts a stream of telemetry — RPM, fuel flow, coolant temp, oil pressure, battery voltage, GPS position — 200 messages per second. It scrolls across your chartplotter and disappears. No history. No trends. No warning when something changes.

Marine Intel captures every message, builds your engine's performance fingerprint, and tells you when something deviates — before it fails, before you need a tow.

Your engine is already telling you what's wrong

These are real insights Marine Intel generates from data your chartplotter discards. No sensors to add — your NMEA 2000 network already broadcasts all of this. You just need something that listens.

Impeller Degradation Detected
+3.8°F trending
baseline
Coolant temp at cruise RPM has risen 3.8°F over 30 days while ambient water temp stayed flat. At the same throttle setting, your engine is running progressively hotter — the signature pattern of impeller wear or raw water flow restriction. Service the cooling system before the next extended run.
Hull Efficiency Declining
-12% over 6 wks
Speed at cruise RPM dropped from 28.4 to 25.0 kts. Fuel burn unchanged — you're pushing harder for less speed. Growth or fouling. Schedule a haul-out before it costs you fuel all season.
Propeller Anomaly
Investigate
Prop slip spiked from 12% to 23% mid-trip. At the same RPM, your GPS speed dropped significantly — increased drag at the prop. Possible blade damage, debris wrap, or fishing line. Inspect before next outing.
Fuel Efficiency — Sweet Spot Found
Optimized
Your best fuel economy is 3.8 MPG at 3,050 RPM (28.1 kts). Above 3,400 RPM, efficiency drops 22% for only 3 kts more speed. Below 2,800, hull drag increases and efficiency drops too. Marine Intel maps your actual fuel curve — not a generic spec sheet — and updates it as conditions change.

From engine to insight in five steps

No sensors to install. No wiring to run. Your NMEA 2000 backbone already carries the data — Marine Intel just starts listening.

One connector. Zero setup.

Marine Intel is a small, sealed device that plugs directly into your NMEA 2000 backbone with a standard M12 connector. It powers from the network, creates its own WiFi hotspot, and starts capturing data immediately. No apps to configure. No wiring to run.

On the water: live engine gauges

The device creates a WiFi hotspot. Open your phone browser — no app to install — and get a full instrument panel. Real-time RPM, fuel rate, coolant temp, oil pressure, battery voltage, GPS speed, and computed metrics like prop power and fuel efficiency.

Works with zero internet. The dashboard runs on the device itself — your phone just displays it.

  • No app install — works in any browser
  • Works offline — no internet needed
  • Real-time WebSocket — updates every second
  • Engine hour tracking + service countdown

At home: trip history & AI insights

When the boat reaches WiFi — at the marina, on your home network, or via your phone's hotspot — data syncs to the cloud automatically. Every trip becomes a permanent record with GPS track, engine metrics, and AI-generated insights.

The cloud dashboard is where the intelligence lives. It compares this trip against your baselines, spots trends across weeks and months, and writes plain-English analysis of what's changing and why.

  • GPS tracks for every trip
  • AI-powered insight feed
  • Season-over-season trend comparison
  • Exportable engine history (adds resale value)
