Overview / What Is Newmar GS-2-100 Ground Strap 100’L X 2W for Boats & Marine Engines
The Newmar GS-2-100 Ground Strap for Boats is a 100-foot long, 2-inch wide copper ground strap engineered for marine environments. It is used to ground marine electrical systems effectively and prevent electrical interference, RF noise, and corrosion issues. Designed for both recreational and commercial vessels, it ensures your boat’s electronic equipment functions smoothly.
This ground strap is made of tinned copper braid, which offers excellent conductivity and corrosion resistance, crucial for saltwater environments. Its flexibility and surface area make it an ideal bonding medium for connecting various metal components to a common ground point.
Top Benefits of Using a Marine Ground Strap
Using a dedicated ground strap like the Newmar GS-2-100 comes with a host of advantages for boat owners and marine engineers alike:
- Superior EMI/RFI Shielding: Prevents electrical noise interference in sensitive electronics.
- Reduces Electrolysis and Corrosion: Helps eliminate stray currents that accelerate corrosion.
- Flexible Design: Easy to install even in tight corners of marine engine rooms.
- High Conductivity: Tinned copper ensures low resistance and reliable performance.
Proper grounding through such straps minimizes the risk of malfunction in VHF radios, GPS units, fishfinders, and autopilot systems. It’s not just a preventive measure but an operational necessity.
Common Grounding Mistakes to Avoid
Marine grounding is critical but often poorly executed. Avoiding these mistakes can save you from costly repairs and signal interference:
1. Improper Terminations: Loose or corroded connections can render the ground system ineffective.
2. Inadequate Strap Size: Using narrower or shorter straps than recommended increases resistance.
3. Ground Loops: Multiple ground paths can create loops, leading to interference and equipment damage.
4. Mixing Grounds: Never combine AC and DC ground paths. This can create serious safety hazards.
Maintenance Tips
To keep your Ground Strap for Boats operating efficiently, regular maintenance is essential. Here’s how you can keep it in top condition:
- Inspect connections monthly for signs of corrosion or loosening.
- Clean contact points with a wire brush and apply dielectric grease if needed.
- Check for strap integrity – any signs of fraying or breaks must be addressed immediately.
- Test grounding continuity with a multimeter every quarter.
These steps not only prolong the life of the strap but also safeguard the connected systems.
How to Install a Ground Strap for Boats the Right Way
Installing a grounding strap isn’t rocket science, but it must be done right to prevent issues down the line. Follow these key steps for a successful installation:
- Map your grounding path from the battery to key metal components and electronics.
- Measure and cut the required length from your 100-foot strap.
- Use proper marine-grade lugs and crimping tools for secure terminations.
- Ensure every metal component (engine blocks, fuel tanks, electronics enclosures) is bonded.
- Secure the strap with insulated clamps every 12–18 inches.
Always refer to ABYC (American Boat & Yacht Council) grounding standards during installation for safety and compliance.

Best Ground Strap for Boats – Durability and Longevity
When selecting the best ground strap for marine use, you want a product that lasts through salt spray, engine heat, vibration, and constant exposure. The Newmar GS-2-100 is engineered to withstand these harsh conditions.
Its 2-inch width provides a low impedance path for grounding currents, ensuring stable electronics performance. The strap’s high strand count also means better flexibility and resistance to fatigue — a crucial factor when mounted across moving parts or tight spaces.
Why Choose Tinned Copper for Marine Grounding?
Tinned copper is the material of choice in marine electrical systems for good reasons:
- Corrosion Resistance: Tin coating protects copper from saltwater corrosion.
- Ease of Soldering: Tinned surfaces bond better with marine terminals.
- Extended Lifespan: Tinned copper lasts significantly longer in marine environments.
The Newmar GS-2-100 Ground Strap for Boats uses tinned copper braid, meeting and exceeding marine standards.
Detailed FAQ Section
What is the main purpose of a ground strap for boats?
A ground strap serves as a bonding conductor, connecting metallic components of a boat to a common ground to prevent electrical interference, reduce corrosion, and improve overall system performance. It protects sensitive electronics like GPS systems, radios, and navigation equipment from RF and EMI interference. Ground straps also reduce the risk of galvanic corrosion by providing a low-resistance path for stray current to flow safely to ground, rather than through submerged metal parts. Without proper grounding, electrical anomalies can not only damage electronics but pose safety hazards as well.
How do I know if my marine ground strap needs replacement?
Common signs include visible fraying, corrosion on the copper braid, loss of flexibility, or increasing electronic interference aboard. If your GPS loses signal, your VHF sounds static-filled, or your fishfinder readings are inconsistent, the grounding system might be compromised. You can use a multimeter to check continuity; high resistance readings indicate poor connections. Physical inspection should also be done every few months, especially if the strap is routed near moving parts or heat sources that could damage it over time.
Is the Newmar GS-2-100 suitable for large vessels or just small boats?
The Newmar GS-2-100 Ground Strap 100’L X 2W is suitable for both small and large vessels. Its generous 100-foot length and 2-inch width provide more than enough capacity for complex marine systems typically found in larger boats and yachts. The tinned copper braid ensures reliable performance even in high-current scenarios or in long bonding runs. Whether you’re outfitting a sailboat, commercial fishing vessel, or luxury yacht, this strap delivers professional-grade performance and durability.
How does this ground strap compare to cheaper alternatives?
While less expensive ground straps may work initially, they often lack marine-grade tinned copper, resulting in faster corrosion and reduced conductivity. The Newmar GS-2-100 is designed for longevity and consistent performance in challenging saltwater conditions. Additionally, it complies with ABYC standards, ensuring compatibility with marine electronics and systems. Investing in a high-quality ground strap like this one prevents future failures, costly repairs, and performance issues with vital onboard systems.
Can I install the ground strap myself or should I hire a professional?
If you’re comfortable working with marine electrical systems and follow proper ABYC guidelines, DIY installation is entirely feasible. However, if you’re unfamiliar with your boat’s grounding system layout or unsure of compliance issues, it’s best to consult a certified marine electrician. Incorrect installation can lead to grounding loops or missed bonding points, which are worse than no grounding at all. Professionals will ensure clean terminations, secure routing, and optimal strap placement to maximize effectiveness and minimize EMI exposure.
Conclusion
The Newmar GS-2-100 Ground Strap for Boats stands out as a premium grounding solution for marine vessels of all sizes. Its rugged build, tinned copper design, and 100-foot length provide unmatched flexibility and performance. Whether you’re addressing grounding issues or planning a new install, this strap brings peace of mind with its proven reliability.
