Mercury – Temperature Sensor | SC1000 Speedometer & VesselView Interface | 56-820386A76

Overview

Some SmartCraft setups rely on a dedicated temp sensor to give accurate water-temperature readings on SC1000 speedometers and VesselView displays. The Mercury 56-820386A76 Temperature Sensor is the piece that makes those readings possible. It gives the helm a steady, real-time temperature signal so the system can display correct values on Axius, select outboard setups, and SC1000-equipped boats. Simple, reliable, and built to drop right into the SmartCraft network.

Key Features

• SmartCraft Temperature Input – Supplies water-temperature data for SC1000 speedometers and VesselView.
• Axius & Outboard Ready – Works with VesselView Axius systems and compatible outboard layouts.
• Stable Temperature Signal – Sends clean, steady data for accurate on-screen readings.
• Plug-In OEM Fit – Uses Mercury factory connectors for a quick, clean installation.
• Essential Add-On Component – Required for systems that depend on an external SmartCraft temp sensor.
• Marine-Grade Build – Designed to handle the heat, moisture, and vibration common in engine compartments.

Compatibility

• SC1000 Speedometer systems
• VesselView Axius installations
• Applicable Mercury outboard SmartCraft setups
• SmartCraft temperature-input circuits

Performance & Practical Benefits

This sensor gives the SmartCraft network the temp signal it needs to display accurate numbers at the helm. Once installed, the gauge or VesselView screen updates reliably, helping you spot cooling-system changes early. Whether you’re watching temperatures during a long cruise or checking conditions in skinny water, the reading is steady and easy to trust.

Why Buy OEM

Temperature sensors must stay accurate over time, and Mercury’s OEM part provides the correct calibration and connector fit the SmartCraft network expects. Aftermarket sensors often drift or lose accuracy, leading to confusing or unreliable readings. The OEM sensor installs cleanly and stays consistent in real marine conditions.

FAQ

Q1: When do I need this temperature sensor?
When using an SC1000 speedometer or a VesselView Axius/outboard setup that requires an external SmartCraft temperature input.

Q2: Does this replace an engine temperature sensor?
No. It provides the SmartCraft temp signal for displays—it doesn’t affect engine operation.

Q3: Will the readings show up automatically?
Yes. Once connected, the SmartCraft display typically recognizes the sensor.

Q4: Is installation difficult?
No. It uses plug-in OEM connectors and mounts like a standard SmartCraft component.

Q5: Can it handle saltwater conditions?
Yes. The housing and connectors are made for long-term marine use.
