Mercury – Oil Level Status Kit | SmartCraft Oil Monitoring Upgrade | 8M0142265

Overview

Some engines give you full SmartCraft oil-level reporting right out of the box, while others need a little help to unlock that feature. The Mercury 8M0142265 Oil Level Status Kit adds that missing link. It gives SmartCraft gauges and VesselView displays the ability to read and show real-time oil level information on engines that weren’t originally equipped with this capability. It’s a simple add-on that makes day-to-day ownership easier and takes the guesswork out of routine checks.

Key Features

• SmartCraft Oil Reporting – Adds live oil-level status to compatible SmartCraft gauges and VesselView displays.
• Upgrade Capability – Optional kit for 3.4L V6 and 4.8L V8 engines that don’t include oil status from the factory.
• Standard on AMS V8 – The 4.6L V8 Verado AMS already includes this feature, so the kit is not required.
• Integrated System Feedback – Lets the driver monitor oil level without opening the cowl.
• Clean OEM Integration – Connects directly into the SmartCraft network for accurate, stable readings.
• Ease of Use – Makes oil checks simple by displaying status right at the helm.

Compatibility

• 3.4L V6 Mercury outboards
• 4.8L V8 Mercury outboards
• 4.6L V8 Verado AMS (feature already built in—kit not required)
• SmartCraft gauges
• VesselView displays

Performance & Practical Benefits

With this kit installed, the engine shares its oil level status directly with the helm. You can see your oil level at a glance, whether you’re running a VesselView screen or a SmartCraft gauge cluster. It reduces the need to open the cowl for routine checks and helps you stay ahead of low-oil situations before they interrupt a day on the water. The integration is clean, the readings are steady, and the convenience makes regular maintenance feel a lot easier.

Why Buy OEM

Oil-level reporting needs reliable communication with the SmartCraft system, and the OEM kit uses the exact logic and connectors Mercury designed for these engines. Aftermarket sensors rarely match SmartCraft’s calibration needs and often produce inconsistent readings. The factory kit installs correctly, lasts longer, and ensures the data shown on your display is accurate.
