Mercury – Stern Data Cable (30 ft, 10-Pin CAN) | Rigging Accessory | 84-8M0174054

Overview
This 30-foot stern data cable is made for boats that need a long, clean run from the transom area to the helm. It carries SmartCraft engine and system data through a 10-pin CAN connection, giving the network a steady signal even on larger layouts. The length makes routing easier when the cable has to travel through long rigging chases or around tight corners. Once it’s installed, gauges and displays usually update more smoothly with fewer dropouts.

Key Features
 • 10-Pin CAN Data Cable – Moves SmartCraft engine and system data through the network.
 • 30-Foot Length – Designed for long hulls or extended rigging paths.
 • Stable Signal Path – Helps reduce flickering or interrupted data.
 • Flexible Marine Jacket – Holds up to vibration and constant movement.
 • OEM Fitment – Connects cleanly with Mercury harnessing and CAN components.

Engine & Boat Compatibility
 • SmartCraft engines
 • CAN network systems
 • Single- and multi-engine rigs
 • DTS and modern digital helm setups

Performance & Practical Benefits
A cable this long lets you route it the right way—no splices, no tight corners, and no stretched spots. That makes the SmartCraft network feel more stable, especially when conditions get bumpy or the boat’s systems are talking heavily. You’ll usually notice smoother gauge updates and fewer random hiccups in the data chain.

Why Buy OEM
OEM CAN cables use the correct shielding, connectors, and insulation for Mercury networks. They latch securely, resist corrosion, and help avoid the odd electrical bugs that show up when aftermarket wiring is used in a CAN system.

FAQ
Q1: When should I use the 30-foot cable?
A: When the stern-to-helm run is too long for shorter cables or your routing path takes several turns.

Q2: Is this cable good for saltwater?
A: Yes—just keep the connectors clean and dry as part of routine maintenance.

Q3: Can I cut or splice this cable if it’s long?
A: No—CAN cables shouldn’t be cut or spliced. Use the proper length instead.

Q4: Anything to check before running it?
A: Make sure the rigging path won’t pinch or kink the cable.

Q5: What if the network still drops data afterward?
A: That usually means another connector or module in the chain needs attention.
