Mercury – SmartCraft / NMEA 2000 GPS Antenna | Auto-Detect Position Source | 8M0130792

Overview

Some systems need SmartCraft data, others need NMEA 2000, and on certain boats you might not know which format you’ll end up using as the helm evolves. The Mercury 8M0130792 GPS Antenna removes all the guesswork. It automatically detects the network it’s plugged into and feeds clean, reliable GPS information to either system without any setup. Whether you’re powering a gauge, a tow feature, an Active Trim module, or a full NMEA 2000 network, this antenna becomes the steady, accurate position source the rest of the helm depends on.

Key Features

• Auto-Detect GPS Output – Automatically identifies SmartCraft or NMEA 2000 networks and communicates in the correct format.
• Universal Position Source – Provides GPS data for systems requiring SmartCraft or N2K speed and position input.
• Multiple Use Cases – Supports SC1000 speed input, SmartTow speed, Active Trim without dash pad, and NMEA 2000 networks.
• Plug-In Installation – Connects directly to the appropriate network with no calibration required.
• Stable Satellite Tracking – Maintains a strong GPS lock for accurate speed and position updates.
• Rugged Marine Housing – Built to withstand long-term outdoor exposure and helm vibration.

Compatibility

• SmartCraft networks
• NMEA 2000 networks
• SC1000 speed input systems
• SmartTow systems needing a GPS speed source
• Active Trim systems without a dash pad speed input
• Multifunction displays requiring NMEA 2000 GPS data

Performance & Practical Benefits

This antenna gives you a stable, fast-acquiring GPS signal that stays locked even when conditions get rough or the boat moves through tight areas. Speed readings become more consistent, position data stays accurate, and features like SmartTow and Active Trim operate the way they were designed to. The auto-detect behavior removes setup headaches—just plug it into the network you’re using, and the antenna handles the format automatically. Once it’s mounted and connected, it works quietly in the background with no tuning or adjustments.

Why Buy OEM

GPS accuracy depends on communication that matches the network’s exact expectations. Mercury’s OEM antenna is built to meet SmartCraft protocol standards while also speaking clean NMEA 2000 language. Aftermarket units often support one system well but struggle with the other. The OEM design handles both correctly, installs easily, and delivers the kind of reliability needed for speed-based features like SmartTow and Active Trim.

FAQ

Q1: Will the antenna choose the correct network automatically?
Yes. It detects whether it’s connected to SmartCraft or NMEA 2000 and switches to the proper format.

Q2: Does this require any calibration or setup?
No. Once connected and powered, the GPS begins transmitting the correct data format on its own.

Q3: Can this serve as the primary GPS source for multiple systems?
Yes, as long as those systems are on the same network and built to accept shared GPS input.

Q4: Is there a benefit over using a chartplotter’s GPS antenna?
This unit delivers a cleaner, more stable feed specifically for SmartCraft and NMEA 2000 functions that rely on speed and position reporting.

Q5: Can it be mounted out of direct weather?
It can, but GPS performance is best with a clear view of the sky for stronger satellite signal.
