Overview

The Garmin 010-10817-04 is a weather cap that covers the connector on your network cable when it is unplugged. It slips over the RJ45-style plug to keep salt spray, moisture, and dock grime off the contacts while you are rigging, troubleshooting, trailering, or storing spare cable runs.

On a boat, network connectors often get exposed during upgrades and service work. Keeping the end protected helps the connector stay clean so it seats properly when you plug back into your Garmin marine network gear.

Key features

• Covers an exposed Garmin network cable connector to keep water and debris out when the cable is not connected
• Helps reduce corrosion risk on the connector contacts in saltwater environments and washdown areas
• Useful during installs and refits when cables are pre-pulled and left unconnected until equipment is mounted
• Installs and removes by hand for quick protection during service work
• Made for network cable connectors, not NMEA 2000, NMEA 0183, or power/data plugs

Compatibility and fit

This cap is for Garmin network cable ends that use an RJ45-style connector. It is meant to protect the cable-side connector, not a device port.

If your boat uses a different Garmin network connector style or adapter hardware, match the cap to the connector type before ordering.

Installation and care

Press the cap fully onto the connector until it sits snug. Before reconnecting the cable, remove the cap and wipe the connector clean and dry if it has been in a wet locker, bilge space, or spray-prone area.

Rinse the cap with fresh water after heavy salt exposure and let it dry before putting it back on or stowing it in your spares kit.

Use on board

This is a good match for boats that see frequent electronics changes, seasonal removals, or troubleshooting at the helm, as well as for installers who stage a network cable run ahead of adding radar, sonar modules, or extra displays.
