Mercury – 1st Mate Safety & Security System | Universal Dual/Triple Engine Kit | 98-8M6007940

Overview

Large multi-engine boats carry more people, more power, and more responsibility. The Mercury 98-8M6007940 1st Mate Dual/Triple Engine Kit adds an extra layer of protection by giving the captain and passengers immediate overboard alerts and a built-in theft-deterrent system. Designed to work with all leading engine brands, this kit brings the core 1st Mate safety features to dual- and triple-engine boats, even if they aren’t running SmartCraft. With the included hub, harness, captain’s fob, and wearable, the system becomes a natural part of your routine on the water.

Key Features

• Multi-Engine Compatibility – Works with dual- or triple-engine setups across all major engine brands.
• Core System Components – Includes the vessel hub, harness, one RFID passenger tag, and the captain’s fob with blue wearable accessories.
• Man-Overboard Alerts – Notifies the captain and onboard passengers immediately if a tagged person falls overboard.
• Engine Lockout Security – Adds a theft-deterrent function when the boat is unattended.
• Wearable Safety Integration – Captain’s fob pairs automatically, and the included blue wearables offer flexible ways to carry it.
• Straightforward Daily Use – System activates and pairs as you move about the boat.

Compatibility

• All leading engine brands (dual or triple engines)
• Mercury SmartCraft engines (for enhanced integration, Mercury-specific kits are available)
• Passenger RFID tags (additional wearables sold separately)

Performance & Practical Benefits

This kit adds two major layers of protection for larger multi-engine boats:
• Immediate awareness if a captain or passenger wearing a tag goes overboard
• A clear theft deterrent through engine lockout when the system is armed

It’s especially valuable on bigger boats where movement, noise, and distance make it harder to notice a fall overboard. Once installed, the system automatically pairs with the captain’s wearable and keeps watch in the background, making boating feel safer and more controlled without adding extra steps.

Why Buy OEM

1st Mate is designed by Mercury to deliver reliable wireless communication, stable alerts, and durable wearables that hold up in harsh marine conditions. Even though this version works with all major engine brands, choosing the OEM kit ensures dependable performance and seamless behavior across multiple engines.
