Mercury – Stern Data Cable (20 ft, 10-Pin CAN) | Rigging Accessory | 84-8M0174053

Overview
This 20-foot stern data cable carries SmartCraft engine and system data from the back of the boat up to the helm through a 10-pin CAN connection. The extra length helps on boats where the cable needs to travel farther or take a less direct route. Once it’s run cleanly, your network usually feels steadier, with fewer random dropouts or flickering readings.

Key Features
 • 10-Pin CAN Cable – Sends SmartCraft data through the network.
 • 20-Foot Length – Ideal for longer or winding rigging runs.
 • Steady Signal Path – Helps cut down on noise or lost data.
 • Flexible Marine Jacket – Built to handle vibration and tight routing.
 • OEM Fit – Matches Mercury connectors and network specs.

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

Performance & Practical Benefits
A longer CAN cable gives you the room to route it the right way—no sharp corners, no stretched sections. That makes the whole SmartCraft network feel more stable. Your gauges and displays tend to behave better, especially when you’re bouncing around in chop or powering up after idle. It’s one of those cables you don’t think about until it’s missing.

Why Buy OEM
OEM CAN cables use proper shielding, proper connectors, and the right insulation for a marine setup. They latch securely, resist corrosion, and help prevent the weird data glitches that cheaper wiring can cause.

FAQ
Q1: When would I need the 20-foot version?
A: When the stern-to-helm run is too long for a 15-foot cable or the route takes a few extra turns.

Q2: Is this cable good for saltwater?
A: Yes—just keep the connector areas clean and dry.

Q3: Can I shorten or splice it?
A: No—splicing CAN cables often causes signal problems. Use the length you actually need.

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

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