Overview

The Garmin 010-11617-53 is a heavy duty transducer extension cable with 8-pin connectors that adds 10 ft of extra reach in your sonar cable run.

It is commonly used when the transducer lead comes up short on larger hulls, forward helms, or refits where the display or sonar module has been moved. The connection stays plug-to-plug, so you can extend the run without cutting into the transducer cable.

Key features

• Adds 10 ft of length for a compatible 8-pin transducer installation
• 8-pin connector style end-to-end so the transducer connection stays consistent
• Heavy duty construction intended for typical marine routing, vibration, and long cable runs
• Installs inline between the transducer cable and the sonar input on your electronics
• Helps when routing through rigging tubes, under-deck chases, or up to a T-top or pilothouse helm

Compatibility and fit

This cable matches Garmin transducers that use the 8-pin plug. It is an extension, not an adapter, so it will not convert between connector types.

Before ordering, confirm your transducer connector is 8-pin and that the existing cable run has room for an inline connector joint at a dry, serviceable point.

Installation and routing

Plan the run so the extension connection ends up somewhere you can reach later, not buried in foam or sealed compartments. Leave a small service loop at both ends so the connectors are not pulled tight when the boat flexes or when equipment is removed for service.

Secure the cable away from sharp fiberglass edges, steering linkages, and moving rigging. If you are chasing intermittent sonar noise, keep the transducer cable run separated from high-current engine and charging wiring where practical.

Use cases on board

This extension is a good match for center consoles, pilothouses, and sailboats where the transducer is aft and the electronics sit well forward, or anytime you are reusing an 8-pin transducer during an electronics upgrade but need a longer reach to the helm.
