How to Install W10/W12 Pantograph Arm, 18-24″ for Marine Use
Installing the W10/W12 Pantograph Arm on your marine vessel is a straightforward process. However, following proper steps ensures optimal functionality and longevity:
- Remove the old arm: If replacing an existing unit, gently lift and unscrew the old wiper arm from the motor shaft.
- Align new pantograph arm: Position the new W10/W12 arm at the desired resting angle. Ensure it’s parallel to the bottom of the windshield when not in use.
- Secure to motor shaft: Mount it onto the motor spindle and tighten the locking nut. Ensure a snug fit but avoid overtightening to prevent thread stripping.
- Adjust length: Using an Allen key or screwdriver, set the arm to your preferred length within the 18-24″ range.
- Attach blade: Mount a compatible blade to the wiper arm connector. Test for full sweep range and pressure.
When installed correctly, the pantograph arm provides stable and balanced movement for improved visibility in tough marine weather.
Pantograph Arm Troubleshooting: Common Issues and Fixes
Though reliable, pantograph arms can face issues, especially under harsh marine conditions. Here are some common problems and their solutions:
1. Wiper arm skips or misses spots
This is typically due to incorrect blade pressure or arm misalignment. Ensure the arm is properly adjusted and the blade is seated correctly. If the arm is loose, tighten the pivot bolts or replace worn joints.
2. Arm doesn’t return to resting position
Often caused by an internal motor problem or improper synchronization of the arm linkage. Check the motor output and recalibrate the arm position.
3. Excessive arm vibration
Can be due to an unbalanced blade or bent pantograph components. Replace damaged parts and verify correct arm alignment to reduce vibration during use.
Maintenance Tips
To ensure the long life of your W10/W12 Pantograph Arm, follow these maintenance practices:
- Rinse After Every Voyage: Saltwater exposure can lead to corrosion. Rinse the arm and blade assembly with fresh water to remove salt and grime.
- Lubricate Joints: Use marine-grade silicone spray or grease to lubricate moving joints quarterly.
- Inspect for Rust or Corrosion: Periodically inspect for signs of wear or oxidation, especially on mounting bolts and joints.
- Replace Wiper Blades: Dull blades can strain the arm’s mechanics. Replace blades every 6–12 months depending on usage.
With basic care, your pantograph arm can operate efficiently for years, maintaining optimal windshield clarity.
Expert Advice and Pro Recommendations
Marine experts agree that investing in high-quality components for navigation visibility is non-negotiable. The W10/W12 Pantograph Arm is engineered to outperform standard arms in marine conditions due to its precise geometry, adjustable length, and stainless construction. Professionals recommend pairing it with UV-resistant silicone wiper blades and routinely checking fasteners for loosening after rough weather.
For fleet or commercial vessels, stocking an extra pantograph arm and set of blades can prevent delays due to unforeseen damage. Additionally, always use marine-specific washers and lock nuts during installation.

Detailed FAQ Section
What is the difference between a pantograph arm and a pendulum arm?
A pantograph arm operates using a dual-arm system that maintains the wiper blade in a parallel motion across the windshield. This ensures even pressure and better wipe coverage, especially important for wider windshields. A pendulum arm, in contrast, swings in an arc from a single pivot point, which can lead to uneven pressure at extreme angles. The pantograph design is preferred for larger or curved marine windshields where visibility is critical.
How do I determine if 18-24″ (457-609mm) is the right length for my boat?
Measure your existing wiper arm or the available sweep area on your boat’s windshield. The W10/W12 Pantograph Arm’s adjustable range of 18 to 24 inches makes it highly adaptable. If your current arm falls within or close to this range, this model will likely fit. Always ensure your wiper motor is compatible with pantograph arms — ideally the W10 or W12 motor series. Consult your boat’s user manual or reach out to our experts if unsure.
How often should I replace my pantograph arm?
With proper maintenance, a marine-grade pantograph arm can last several years. However, exposure to salt, UV, and mechanical stress can shorten its lifespan. If you notice rust, reduced wipe quality, or looseness in joints, it may be time for a replacement. Most users replace their arm every 2-3 years or as needed based on performance and inspection findings.
Can I install the pantograph arm myself?
Yes, the W10/W12 Pantograph Arm is designed for easy DIY installation. All you need are basic hand tools like a screwdriver and Allen key. Make sure to follow the instructions and align the arm correctly. Always test the wiper system after installation to confirm smooth operation. If you’re unfamiliar with wiper systems, a professional installer can complete the task in under 30 minutes.
Is this pantograph arm suitable for commercial vessels?
Absolutely. The W10/W12 Pantograph Arm is used widely across both recreational and commercial vessels due to its reliability and construction quality. Its corrosion-resistant materials and performance under demanding marine conditions make it ideal for commercial boats, fishing vessels, and even patrol crafts. Pair it with a heavy-duty wiper blade and motor system for maximum effectiveness.
Conclusion
The W10/W12 Pantograph Arm, 18-24″ (457-609mm) is a premium-grade, adjustable solution for maintaining clear visibility on the water.
