Garmin 010-10817-03 Weather Cap For Powercable

Shield Your Garmin GPSMAP from Marine Elements

Out on the water, where saltwater spray, relentless UV exposure, and sudden downpours test every piece of gear, safeguarding your electronics starts with the smallest details. This weather cap slips over the connector on your power and data cable, creating a reliable barrier against moisture, corrosion, and debris. Designed specifically for boaters who demand durability, it ensures your GPSMAP series chartplotter stays operational through rough seas and long voyages.

Real-World Protection for Boating Adventures

Marine environments are unforgiving—salt crystals can infiltrate connections, leading to intermittent power issues or total failure. By sealing the exposed power/data cable end, this cap prevents water ingress during waves crashing over the helm or heavy rain. Boaters report fewer corrosion spots and extended cable life, keeping navigation reliable when you need it most, like plotting courses in foggy conditions or tracking fish in tournaments.

Seamless Fit with GPSMAP Series

Engineered to match the rugged build of Garmin's GPSMAP lineup, this black weather cap integrates without bulk, maintaining a clean deck setup. Whether you're running a compact 943x or a full-featured 8616xsv, it snaps on securely, preserving the sleek aesthetics while adding essential protection. No tools required—just position and secure for instant defense against the elements.

Easy Installation and Everyday Reliability

• Locate the power/data cable connector on your GPSMAP unit.
• Slide the cap over the end until it seats firmly.
• Resume normal use; the flexible material adapts to cable movement without slipping.

Its tough, UV-resistant construction withstands years of sun and spray, outlasting makeshift covers like tape or plastic bags that degrade quickly.

Boost Longevity and Performance

Beyond basic shielding, this accessory minimizes downtime by preventing oxidation on pins, which can cause signal dropouts or inaccurate readings. Pair it with routine cable inspections for peak performance—check for cracks seasonally and clean with fresh water after saltwater exposure. Anglers, cruisers, and commercial operators alike value how it maintains crisp sonar images and precise GPS fixes over extended trips.

Pro Tips for Marine Gear Care

• Rinse cables with freshwater after every outing to remove salt residue.
• Store in a dry locker during off-season to avoid humidity buildup.
• Combine with dielectric grease on contacts for extra corrosion resistance.
• Inspect during annual haul-outs to catch wear early.
