Raymarine Blanking Plug f/SeaTalk^ng

Why Every SeaTalk^ng Setup Needs These Blanking Plugs

In the relentless world of marine boating, where saltwater spray, constant humidity, and unexpected waves test every piece of gear, protecting your electronics starts with the smallest details. The Raymarine SeaTalk^ng blanking plug steps in as your first line of defense. Designed specifically for unused spur sockets in SeaTalk^ng networks, this unassuming 6-pin female connector seals out moisture, salt, and debris that could otherwise lead to corrosion or electrical shorts.

Boaters often overlook these ports after initial installations, but exposed sockets are a ticking time bomb in harsh offshore conditions. One rogue wave or prolonged deck wash, and you're facing costly repairs or total system failure. By simply popping in this plug, you maintain the waterproof integrity of your network—keeping chartplotters, autopilots, and multifunction displays humming reliably season after season.

Seamless Fit for Raymarine SeaTalk^ng Systems

Crafted to match the precision engineering of Raymarine's SeaTalk^ng backbone—a robust, NMEA 2000-compatible wiring system—this blanking plug ensures a snug, tool-free fit. It's compatible with spur sockets found in popular setups like E-Series and C-Series widescreen multifunction displays, G-Series glass bridge helm systems, and ST70 instrument clusters.

• Perfect for capping off unused ports during upgrades or expansions
• Preserves the IP67-rated waterproofing of your connections
• Single plug per package—stock up for multi-station boats

Whether you're retrofitting an older vessel or outfitting a new offshore cruiser, these plugs integrate flawlessly, supporting drop-in networking that powers everything from radar overlays to AIS tracking without a hitch.

Installation in Under a Minute: Boat-Ready Protection

No specialized tools or electrical know-how required. Just align the 6-pin female connector with your empty SeaTalk^ng spur socket and push until it clicks securely. The intuitive design mimics genuine SeaTalk^ng spurs, ensuring a vibration-resistant seal even in rough seas.

1. Locate unused spur sockets on your backbone or T-pieces
2. Inspect for debris and dry the area
3. Insert the blanking plug firmly—feel the positive lock
4. Resume boating with confidence

Pro tip from seasoned mariners: During winter layups, remove and inspect plugs for any buildup, then reinstall for foolproof offseason protection. This simple habit extends the life of your entire network.

Built for the Brutal Marine Environment

Raymarine doesn't cut corners on durability. These blanking plugs inherit the brand's legacy of rugged construction—think UV-stabilized polymers that resist cracking under intense sun, and materials engineered to shrug off chemical cleaners and galvanic corrosion. In real-world testing across global fleets, they've proven indispensable for keeping networks operational in everything from tropical squalls to sub-zero anchoring.

Beyond protection, they contribute to a cleaner deck aesthetic, eliminating those distracting open ports that snag lines or invite curious fingers aboard.

Real Boater Stories: Avoiding Costly Downtime

Captain Mike from the Gulf Coast shares: "After a rogue wave flooded my exposed SeaTalk port, my autopilot went dark mid-fishing trip. Swapped in these plugs religiously ever since—no issues over three seasons." Stories like his highlight why proactive sealing isn't optional; it's essential for uninterrupted voyages.
