Mercury – Top Mount Kit (GPS) | SmartCraft / NMEA 2000 Mounting | 98-8M6009518

Overview

A good GPS antenna needs a clean mounting point if you want strong, uninterrupted satellite reception. The Mercury 98-8M6009518 Top Mount Kit gives you a compact, stable platform for installing a SmartCraft or NMEA 2000 GPS antenna on the helm, hardtop, or console. It keeps the antenna elevated, secure, and positioned for the best signal, especially on boats where space is tight or mounting angles are limited.

Key Features

• GPS Mounting Platform – Provides a solid base for SmartCraft or NMEA 2000 GPS antennas.
• Compact Footprint – Fits cleanly on crowded helms, consoles, and hardtops.
• Stable Elevation – Raises the antenna for clearer satellite visibility and stronger signal lock.
• OEM Replacement Mount – Same top-mount design included with the 8M6012227 GPS kit.
• Durable Marine Construction – Built to handle sun exposure, vibration, and long-term use.
• Straightforward Installation – Secures easily to flat mounting surfaces with standard hardware.

Compatibility

• SmartCraft GPS antennas
• NMEA 2000 GPS antennas
• Systems requiring an external GPS mounting solution
• Replacement mount for GPS Kit 8M6012227

Performance & Practical Benefits

A well-positioned GPS antenna makes a noticeable difference in how cleanly your helm receives speed and position data. This mount lifts the antenna into a clear line of sight, reducing dropouts and improving overall responsiveness for SmartCraft and NMEA 2000 functions. The compact footprint lets it fit where larger mounts will not, and the stable base keeps vibration from affecting GPS performance. Once installed, it quietly supports the antenna without needing attention.

Why Buy OEM

GPS mounting hardware needs the right dimensions and stability to keep the antenna performing as intended. Mercury’s OEM mount matches the antenna’s base precisely and holds up better to heat and vibration than generic brackets. Using the original design ensures a secure fit and long-term reliability, especially for systems that rely on accurate GPS speed and position data.

FAQ

Q1: Is this the same mount included in the 8M6012227 GPS kit?
Yes. This is the standalone version of the mount supplied in that kit.

Q2: What antennas can be installed on this mount?
Any SmartCraft or NMEA 2000 GPS antenna designed for Mercury’s standard mounting pattern.

Q3: Does the mount improve GPS performance?
It provides elevation and stability, which help the antenna maintain a clearer, more consistent satellite lock.

Q4: Can it be installed on non-flat surfaces?
For best results, it should be mounted on a flat surface to keep the antenna level.

Q5: Is it suitable for saltwater environments?
Yes. The materials are built for long-term exposure in both saltwater and freshwater conditions.
