Mercury – SmartCraft Terminator Assembly | CAN 1/P & H Network End Point | 8M0055652

Overview

A SmartCraft network relies on proper termination to keep data flowing smoothly, and the red terminator is one of the key pieces that keeps that backbone stable. The Mercury 8M0055652 Terminator Assembly provides the correct end load for CAN 1/P and H circuits, giving the system a clean, controlled endpoint that prevents signal noise and dropouts. It’s a small component, but it plays a big role in keeping gauges, modules, and engine data working the way they should.

Key Features

• CAN 1/P & H Terminator – Provides proper electrical termination for SmartCraft CAN 1/P and H networks.
• Red-Coded Housing – Identifies the correct terminator type for its designated SmartCraft circuits.
• Network Stabilization – Helps prevent data glitches, dropped packets, and intermittent faults.
• SmartCraft Ready – Designed for use at the end of SmartCraft harness or junction box network runs.
• OEM Electrical Spec – Matches Mercury’s required resistance and communication standards.
• Quick, Secure Fit – Installs easily into the designated network port without tools.

Compatibility

• SmartCraft CAN 1 networks
• SmartCraft CAN P networks
• SmartCraft CAN H circuits
• SmartCraft harness and junction box termination points

Performance & Practical Benefits

When the network is properly terminated, SmartCraft readings stay clean and consistent. This terminator assembly keeps the system from “floating,” which helps modules, gauges, sensors, and displays communicate without lag or dropouts. It’s especially important on boats with multiple SmartCraft devices, where even small instability can create nuisance warnings or unreliable data. Once installed, the network settles into a smooth, predictable communication pattern.

Why Buy OEM

The SmartCraft system is sensitive to resistance values and signal quality. Mercury’s OEM terminator assembly uses the exact specification required for CAN 1/P and H circuits, ensuring proper load and stable communication. Aftermarket components often miss the correct electrical range, leading to phantom faults or intermittent behavior. The OEM piece guarantees the clean, reliable termination the network depends on.

FAQ

Q1: How do I know if my network needs this terminator?
If an end point on a CAN 1/P or H branch is open or missing its terminator, the network will often show unstable or inconsistent data.

Q2: Can a bad terminator cause random alarms?
Yes. Incorrect or missing termination can lead to dropped messages that trigger nuisance alerts.

Q3: Is installation difficult?
No. It plugs directly into the proper network port without tools.

Q4: Can this terminator be used anywhere in the network?
It should only be used at the end of a CAN 1/P or H run, not in the middle of the chain.

Q5: Will this hold up in saltwater conditions?
Yes. The housing and contacts are designed for long-term marine use when properly installed.
