Lowrance 000-0127-30 ETHEXT-25YL — 25 ft Ethernet Extension Cable
The Lowrance ETHEXT-25YL is a 25-foot Ethernet extension cable for Lowrance marine displays equipped with the yellow 5-pin Ethernet networking interface. It is the longest standard option in the Lowrance ETHEXT cable family, designed for larger vessels or complex helm layouts where longer cable runs are required between networked displays and accessories.

Installation Notes
- Verify your display has a yellow 5-pin Ethernet port before ordering — not all Lowrance displays include Ethernet networking
- This cable extends an existing Ethernet run; it does not replace a standard network cable where both ends connect directly to display ports
- Ensure connectors are fully seated at both ends — the yellow 5-pin connector requires firm, straight insertion to seat correctly
- Route cable away from high-current DC wiring and ignition sources to minimise interference
- Use cable clips or conduit to secure the run and prevent chafe on longer 25 ft routes through bulkheads or under helm panels
Parts Desk Insights
Best Use Case: The ETHEXT-25YL is the right choice for larger boats where the head unit and a networked device — such as a radar or second display station — are mounted far apart and a 6 ft or 15 ft cable won’t reach cleanly. It’s commonly used on center consoles with a forward display station, flybridge setups, and sportfisher helms where cable needs to run through the hardtop or down into a cabin.
Common Issues: On a 25 ft run, the two most common issues are connector seating (especially if the cable is routed through tight spaces that put tension on the ends) and EMI interference when the cable runs parallel to engine harnesses or VHF coax over long distances. Route with generous bend radius and avoid running alongside high-current wiring. If you don’t need the full 25 ft, consider the ETHEXT-15YL 15 ft or ETHEXT-6YL 6 ft to keep the installation tidy.
