Raymarine Transducer Extension Cable, For A Series and C/E Series Sounders, 3 m

Overview

The Raymarine E66074 is a 3 m transducer extension cable for selected Raymarine sonar and fishfinder installations. It adds 3 m (9.8 ft) to the cable run, which helps when the transducer lead falls short between the mounting point and the display or sonar connection point.

This is the kind of cable you use when the rest of the sonar setup is already right and the only problem is reach. On a boat, that usually comes up after a transducer is mounted on the transom or through the hull and the final path to the helm, electronics box, or adapter cable turns out longer than expected.

It is an in-line extension for compatible transducer connections, not a network cable or power lead. Fit depends on the connector style in the existing sonar setup, so it is worth checking the transducer connection already on the boat before ordering.

Key features

• Adds 3 m (9.8 ft) of extra length to a compatible transducer cable run
• Plug-together connection for a straightforward in-line extension
• Used with selected Raymarine sonar and fishfinder setups, including older A Series applications and other compatible legacy transducer runs
• Useful when the transducer cable needs to reach from the transom, hull, or bilge area to a helm-mounted display or related sonar connection point

Compatibility and fit

This cable is best matched by connector type and sonar family rather than by display name alone. It is commonly used where a compatible Raymarine transducer setup needs a short extension without changing the transducer itself or reworking the whole cable run.

For refits and replacement work, this matters most on larger center consoles, pilothouse boats, walkarounds, and smaller cruisers where cable routing can be tight and the distance from the transducer location to the helm is longer than first expected. It also helps when electronics are being moved to a new dash panel or equipment box during an upgrade.

Installation and setup

Installation is straightforward because the cable sits in-line between the compatible transducer lead and the rest of the sonar cable path. That makes it a practical fix when a clean factory-style extension is preferred over stretching the original cable or trying to reroute it through a harder path.

For the cleanest result on board, route the cable clear of VHF wiring, ignition wiring, and other high-noise electrical runs, secure it so it does not move under vibration, and keep the connectors out of standing water where possible. Those small details make a difference on boats that see regular washdown, pounding in chop, or long days offshore.

Use on board

This is a good match for boat owners finishing a sonar install, moving a display, or replacing older Raymarine equipment where the original transducer cable just misses the new location. It suits installations where adding a modest amount of length is all that is needed to complete the job cleanly.
