Mercury – GPS Extension Cable | 9.8-Foot CAN P Line | 84-879171T23

Overview

Longer boats and wider helm layouts sometimes need more reach than the factory GPS cable provides. The Mercury 84-879171T23 Extension Cable adds 9.8 feet to the GPS line used with the 8M0024918 kit, giving you enough length to route the antenna cleanly across larger consoles or more spread-out rigging paths. Built for CAN P GPS systems without an Auto Pilot module, it extends the signal without adding noise or setup steps.

Key Features

• 9.8-Foot Extension – Offers generous extra length for long rigging runs or distant mounting points.
• CAN P GPS Signal – Designed for the dedicated GPS feed used on non-Auto Pilot systems.
• GPS Kit Compatible – Intended for use with Mercury’s 8M0024918 GPS Kit.
• OEM Connectors – Uses factory plug-in ends for a secure, no-guesswork installation.
• Clean Data Transfer – Maintains a steady GPS signal across the added distance.
• Flexible Routing – Slim, easy-to-run cable for clean paths through tight or complex rigging areas.

Compatibility

• GPS Kit 8M0024918
• CAN P GPS systems
• Boats without Auto Pilot modules

Performance & Practical Benefits

This extension cable makes it easier to place the GPS antenna where it performs best—usually high, open, and away from metal or electronics that cause interference. Larger boats especially benefit from the extra length, allowing cleaner rigging and better antenna placement. Once connected, the system continues delivering stable GPS information for speed and position without any calibration or setup work.

Why Buy OEM

GPS signals are sensitive to poor connectors and cheap wiring. Mercury’s OEM cable keeps the CAN P signal clean and stable, avoiding the dropouts or noise problems that often show up with aftermarket extensions. With the factory cable, the connection stays reliable through vibration, heat, and long days on the water.

FAQ

Q1: When is the 9.8-foot extension the right choice?
If the GPS antenna needs to reach a distant helm location or cross a wide rigging path, this longer cable provides the needed flexibility.

Q2: Does the added length affect GPS performance?
No. The cable is built to carry CAN P data cleanly over this distance.

Q3: Can this extension be used with Auto Pilot systems?
It’s meant for boats without an Auto Pilot module in the GPS signal chain.

Q4: Is the cable easy to route in tight areas?
Yes. It’s slim and flexible for running through narrow channels or behind consoles.

Q5: Does the system need to be reset after installing the cable?
No. Just connect it inline and the GPS feed continues normally.
