Garmin 8-Pin Transducer Extension Cable, For Compatible Sounders

Overview

The Garmin 8-Pin Transducer Extension Cable is an 8-pin pass-through cable that adds reach between a compatible 8-pin Garmin transducer and a compatible sounder or chartplotter. It is available in 10 ft (3 m) and 30 ft (9 m) lengths for installs where the factory transducer lead does not comfortably reach the helm, electronics box, or sonar module mounting location.

This is a straightforward extension, not an adapter. It keeps the original plug connection intact so you can route the run cleanly through rigging tubes, under decks, or up a console without cutting and re-terminating a transducer cable.

Key features

• 8-pin extension for compatible Garmin transducer-to-sounder connections.
• Length options cover short console runs and longer center console, pilothouse, and aft-mount transducer layouts (10 ft or 30 ft).
• Maintains a plug-in connection instead of splicing transducer wiring.
• Useful when the transducer is mounted aft or through-hull and the display or sonar module is mounted forward.
• Made to extend an 8-pin setup only, it does not convert between 4-pin, 8-pin, or 12-pin connector types.

Variants

This cable is offered in multiple lengths to match different boat layouts and routing paths.

The length changes between versions. The connector format remains 8-pin to extend a compatible 8-pin transducer lead.

• 010-11617-50: Length 10 ft (3 m). This fits tighter runs where the transducer lead is just short once it is routed through a rigging tube or console chase.
• 010-11617-52: Length 30 ft (9 m). This supports longer routing on boats where the transducer is far from the display or where the cable needs to follow a protected path instead of the shortest line.

Compatibility and fit

Confirm you have an 8-pin Garmin transducer connector and a matching 8-pin connection at the sounder, sonar module, or chartplotter. If your system uses a different pin count, this extension will not mate correctly.

Installation and routing

Plan the route before pulling the cable. Aim for a path that avoids sharp bends, pinch points under hatches, and areas where gear gets stored or stepped on. Leave a small service loop near the display or module so the connector can be accessed later without re-pulling the run.

Support the cable along its length to prevent vibration wear, and keep the connector junction in a location that stays as dry as practical. If the connection must be in a damp space, mount it high and away from standing water and provide a drip loop so water does not track directly into the connector area.

Use on board

This extension is a good match for boats that place the transducer on the transom, jack plate, or through-hull while keeping electronics at the helm, inside a console, or in a cabin. It is also handy when you are re-routing wiring during an electronics refit and want the cable run to follow clean rigging paths instead of a direct shortcut.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
