Overview

The Garmin 010-10817-02 is a 19-pin weather cap for the connector on a Garmin NMEA 0183 cable. Use it anytime the cable end is disconnected so the contacts stay covered instead of sitting exposed to spray, salt, and grime behind the helm.

It is a small part, but it matters when your NMEA 0183 wiring runs through damp consoles, rigging tubes, or electronics boxes. Keeping the connector clean helps the plug seat properly the next time you hook equipment back up after service or seasonal storage.

Key features

• 19-pin protective cap for Garmin NMEA 0183 cable connectors
• Covers exposed contacts when the cable is disconnected or stored
• Helps keep moisture, salt, and debris off the connector to reduce corrosion risk
• Tether keeps the cap attached to the cable end so it is less likely to get lost behind the dash
• Useful for seasonal storage, service work, and spare NMEA 0183 leads kept on board

Compatibility and fit

This cap matches Garmin NMEA 0183 cables that use the 19-pin connector style. If your boat has multiple Garmin cable types on board, verify the connector and pin count on the cable you want to protect before ordering.

Installation and handling

Fit the cap over the connector whenever the cable is unplugged, then route the tether so the cap stays close when you reconnect. It is handy during troubleshooting, winterizing, or anytime equipment gets pulled from the dash for access.

Maintenance and care

If the cap gets soaked during a washdown, rinse off salt and let it dry before reinstalling. Replacing a missing cap is also a simple way to keep unused connectors protected and your electronics bay looking organized.
