Overview

The Garmin 010-12928-00 is a thru-hull stem extender for compatible Panoptix LiveScope transducer installations, adding 6 inches of extra stem length when the hull section or keel depth leaves you short on threads.

It threads on using a thread-to-thread connection, so it installs in-line with the existing stem. More than one extender can be stacked when you need even more reach.

Key features

• Adds 6 inches of stem length to a compatible Panoptix LiveScope thru-hull transducer stem.
• Thread-to-thread assembly keeps the extension in-line with the existing thru-hull stem.
• Multiple extenders can be threaded together for very thick hulls or deep-keel installations.
• Helps maintain proper thread engagement for the retaining hardware on thru-hull mounts where the hull laminate is thick.

Compatibility and fit

Use this extender only on Panoptix LiveScope transducer thru-hull stems that match the original threaded stem. It is intended for thru-hull installs, not transom or trolling-motor mounts.

Before ordering, measure the total thickness you need to span (hull plus any fairing block or backing) and compare it to the available stem length on your installation.

Installation and setup

Dry-fit the extender to confirm clean thread engagement, then thread it fully onto the stem so the joint seats square. After the extender is in place, install the transducer and retaining hardware as normal and verify the stem is not in a bind.

On deep-vee hulls and boats with pronounced keels, plan the cable path so it is protected from chafe and avoids tight bends near the thru-hull fitting.

On-board use

This part is a practical add-on for anglers and cruisers running LiveScope thru-hull setups on boats with thick fiberglass, a cored bottom, or a deeper keel where the standard stem length does not reach comfortably.
