Overview / What Is Newmar GS-2-25 Ground Strap 25’L X 2W for Boats & Marine Engines
The Newmar GS-2-25 Ground Strap for Boats is a durable, marine-grade tinned copper braid grounding strap specifically built for boats and marine engine installations. With dimensions of 25 feet in length and 2 inches in width, it is ideal for grounding multiple components within smaller vessels or segmented areas of larger vessels.
Its purpose is simple but vital: provide a low-resistance path to the boat’s common ground. This prevents the buildup of stray current, reduces electrolysis-related corrosion, and eliminates electrical interference affecting onboard navigation, communication, and monitoring equipment.
Why Marine Grounding Is Essential for Electrical Safety
Proper grounding using a marine-grade strap like the Newmar GS-2-25 is not a luxury—it’s a necessity. Grounding plays a significant role in:
- Protecting Electronics: Prevents damage from electrical surges and interference.
- Reducing Electrolysis: Stops stray currents from corroding metal hull components.
- Enhancing Performance: Ensures clear signals in radios, GPS, and fishfinders.
- Safety Compliance: Meets ABYC grounding standards for marine vessels.
Grounding systems are especially important on aluminum or steel boats and those with multiple onboard AC and DC systems.
Key Features of the Newmar GS-2-25 Ground Strap for Boats
This strap is specifically designed for smaller applications or segments within larger grounding systems. Its advantages include:
- Tinned Copper Braid: Resists corrosion and ensures high conductivity.
- Marine-Grade Flexibility: Easily installs in tight or irregular spaces.
- 2″ Wide Surface Area: Provides excellent electrical bonding performance.
- 25-Foot Length: Ideal for compartment-specific grounding (e.g., engine room or helm).
Pair this strap with proper terminals, clamps, and corrosion protection for best results.
How to Install the Newmar GS-2-25 Ground Strap for Boats
Installation of the Ground Strap for Boats is a straightforward process if you’re familiar with marine electrical systems. Follow these general steps:
- Plan the Path: Identify all components that need grounding (batteries, bonding strips, electronics).
- Measure & Cut: Use only what you need from the 25′ length; clean cuts reduce resistance.
- Crimp Lugs: Use marine-grade lugs and crimpers to attach terminals at the ends.
- Secure with Clamps: Affix the strap every 12–18 inches using insulated P-clamps or adhesive mounts.
- Test Continuity: After install, use a multimeter to ensure proper grounding path and continuity.
Improper installation can result in signal interference, corrosion, or failure of sensitive equipment.
Maintenance Tips
Keeping your Newmar GS-2-25 Ground Strap for Boats in optimal condition ensures long-term reliability. Maintenance tips include:
- Monthly Inspection: Look for signs of corrosion, fraying, or loose clamps.
- Annual Resistance Test: Check continuity and impedance with a multimeter.
- Protective Coating: Apply dielectric grease or corrosion inhibitor to lugs.
- Avoid Physical Damage: Ensure it’s routed away from moving parts or heat sources.
Routine maintenance guarantees the integrity of your boat’s electrical ground system year after year.
Expert Advice and Pro Recommendations
Professionals highly recommend the Newmar GS-2-25 Ground Strap 25’L X 2W due to its compact versatility and robust design. It’s perfect for situations where a full 100’ strap is overkill or difficult to manage in smaller compartments. It’s particularly useful in:
- Outboard Grounding – Connect your motor bracket, fuel tanks, and battery tray with a common strap.
- Helm Electronics Bonding – Prevent interference in GPS, VHF, and radar systems.

Best Ground Strap Options for Compact Installations
When choosing a ground strap for tighter installations, key considerations include strap length, flexibility, resistance to corrosion, and compatibility with terminals. The GS-2-25 excels in all these categories and is a top-tier option for small-to-mid size boats or secondary grounding paths.
Other options may lack tinned copper or be too stiff for reliable installation. Make sure your strap supports full marine compliance and can handle environmental stress like saltwater exposure and temperature fluctuations.
Ground Strap for Boats Troubleshooting Tips
If your boat is showing signs of electrical malfunction—like VHF interference, inaccurate GPS data, or erratic engine behavior—it could be a grounding issue. Use these steps to troubleshoot:
- Check All Connections: Loose or oxidized lugs are common culprits.
- Test Continuity: Use a multimeter to verify consistent low-resistance paths.
- Look for Ground Loops: Multiple paths to the same point can create interference.
- Replace Damaged Straps: Any sign of wear is reason to replace the strap.
The Newmar GS-2-25 Ground Strap for Boats makes replacement easy and efficient.
Detailed FAQ Section
What makes the Newmar GS-2-25 better than other ground straps?
Unlike generic straps, the GS-2-25 is made of tinned copper braid specifically engineered for marine use. It resists corrosion, offers high conductivity, and meets ABYC standards. The 2” width allows superior bonding surface area, while the 25’ length makes it practical for smaller compartments or multiple short runs within a boat. It’s also manufactured by Newmar—a trusted name in marine electrical systems. These advantages make it a better investment over cheaper, unshielded, or untinned alternatives that degrade quickly in saltwater environments.
How long will the Newmar GS-2-25 Ground Strap last?
With proper installation and periodic inspection, the strap can last upwards of 10–15 years in active marine use. Its marine-grade materials and tinned copper composition ensure maximum resistance against corrosion, oxidation, and wear. Environmental factors such as humidity, saltwater exposure, and engine heat may affect lifespan, but with the right protective steps (e.g., using dielectric grease), this strap holds up under harsh conditions for well over a decade.
Can I use the GS-2-25 in both saltwater and freshwater boats?
Yes, the GS-2-25 is designed to perform in both freshwater and saltwater conditions. However, it’s particularly advantageous in saltwater environments where corrosion is a bigger threat. Tinned copper outperforms plain copper in resisting salt-induced degradation. If you’re operating in mixed waters or marina environments where galvanic corrosion is a concern, this strap helps ensure all bonded components discharge electrical noise and stray currents effectively and safely.
Is this ground strap suitable for grounding marine electronics?
Absolutely. The Newmar GS-2-25 is ideal for grounding VHF radios, GPS units, autopilot systems, and sonar equipment. Proper grounding minimizes electromagnetic interference (EMI), which is a common issue with sensitive electronics. Installing the strap between the electronics and the boat’s grounding bus provides a noise-free environment for critical navigation and communication tools. The strap’s wide braid and high conductivity ensure low-resistance paths required for clear signal operations.
Do I need any special tools to install the GS-2-25 Ground Strap?
You’ll need marine-grade crimping tools for lug installation, a wire cutter for trimming the strap to length, and a multimeter to check continuity after setup. Insulated P-clamps, screws, and adhesive mounting options may also be useful to secure the strap along its routing path. No welding or soldering is required. Basic electrical tools and a methodical approach are sufficient for safe and compliant installation.
Conclusion
The Newmar GS-2-25 Ground Strap for Boats is a critical component for any marine electrical system. Compact, powerful, and designed for marine-grade reliability, it offers everything you need for solid grounding in smaller vessels or localized compartments. From reducing signal noise to preventing corrosion, this product pays for itself in long-term system stability and reduced maintenance.
