Whether you own a sailboat, powerboat, or commercial work vessel, this pantograph arm provides the reliability needed during your voyages. It’s compatible with matching W10/W12 wiper motors and integrates seamlessly into your boat’s helm system. Designed with safety and efficiency in mind, the 13-18” adjustable length ensures tailored fitment across multiple vessel types and layouts.
Overview / What Is W10/W12 Pantograph Arm, 13-18″ (330-457mm)?
The W10/W12 Pantograph Arm, 13-18″ (330-457mm), is an adjustable marine-grade wiper arm designed for use with pantograph wiper systems. Unlike conventional pendulum arms, pantograph arms feature two connected arms that move in unison, providing parallel wiping motion. This allows the wiper blade to stay perpendicular to the windshield for maximum coverage and efficiency.
Designed to work with W10 and W12 series wiper motors, this arm offers a black-coated corrosion-resistant finish, ideal for long-term saltwater exposure. Its adjustable length range of 330-457mm makes it suitable for narrow or curved marine windshields often found on small to mid-sized boats. Its compact size makes it an excellent choice for boats with limited windshield space where traditional long pendulum arms may not work effectively.
Applications and Use Cases for Pantograph Arms in Marine Settings
The W10/W12 Pantograph Arm is versatile and applicable across a range of marine vessel types, including:
- Fishing Boats: Ensures uninterrupted visibility during early morning trips or rainy offshore conditions.
- Sailboats: Ideal for small cockpit windshields where compact arm systems are needed.
- Cabin Cruisers: Provides efficient, streak-free wiping on curved or sloped windshields.
- Commercial Vessels: Trusted for consistent wiping action on small workboats or patrol crafts.
Its adjustable range ensures a snug fit and compatibility across various boat designs. The pantograph motion also reduces stress on the blade and motor, extending component lifespan.
How to Install W10/W12 Pantograph Arm on Marine Windshields
Installing the W10/W12 Pantograph Arm is straightforward with the right tools and a compatible wiper motor. Follow these steps for best results:
- Ensure your boat has a W10 or W12 motor installed with the correct spindle.
- Align the base arm with the primary motor spindle, then attach the secondary arm to the linkage mount.
- Adjust the length of the arm to fit your desired sweep path (between 330mm and 457mm).
- Secure the bolts using a marine-grade wrench and ensure proper tension without over-tightening.
- Test the sweep path to confirm blade-to-glass contact and full range of motion.
Note: Always disconnect electrical power before installation to prevent accidental motor movement.
Benefits of Using W10/W12 Pantograph Arm for Marine Wipers
There are numerous advantages to using a pantograph-style wiper arm, especially in marine applications:
- Consistent Pressure: Two-arm design maintains uniform pressure across the entire blade.
- Better Wipe Coverage: Keeps the blade perpendicular to the glass during movement.
- Enhanced Durability: Reduced torque on motor compared to single-arm pendulum systems.
- Corrosion Resistant: Ideal for use in saltwater and coastal environments.
When used in combination with marine-grade wiper blades, the W10/W12 Pantograph Arm ensures extended functionality even in the harshest weather conditions.
Maintenance Tips
Proper care extends the life of your marine wiper arm. Here are essential maintenance tips for the W10/W12 Pantograph Arm:
- Rinse with Freshwater: After every marine outing, rinse the arm with clean water to remove salt and grit.
- Inspect Joints: Look for signs of corrosion or joint fatigue every few months.
- Lubricate Periodically: Use silicone or marine-grade grease on pivot points and hinges.
- Check Blade Alignment: Ensure that the blade sits evenly against the windshield to avoid streaking or gaps.
These basic care steps can dramatically reduce the risk of premature wear or motor stress. Make arm maintenance part of your regular boat inspection checklist.
Expert Advice and Pro Recommendations
Marine professionals often recommend pantograph arms like the W10/W12 for vessels where windshield coverage is essential but space is limited. Their superior blade control and balanced movement make them ideal for tight spaces and low-profile windshields. For even better results, always pair with a high-quality marine blade and ensure proper torque from the wiper motor.

Detailed FAQ Section
What is the main difference between pantograph and pendulum arms?
Pantograph arms like the W10/W12 differ from pendulum arms in that they use a dual-arm mechanism that moves the wiper blade in a parallel path across the windshield. This ensures consistent angle and pressure throughout the sweep, which reduces streaking and improves visibility. Pendulum arms, in contrast, pivot from a single point and tend to arc across the surface, which can lead to uneven coverage. Pantograph systems are preferred on wider or low-profile windshields where maximum surface contact is critical for safe navigation.
How to troubleshoot poor wiping performance on a pantograph arm?
Poor wiping performance with a W10/W12 Pantograph Arm may stem from misalignment, blade wear, or corrosion at the pivot joints. Start by inspecting the blade for signs of wear or hardening. Next, check that the arm is properly mounted and tensioned. Lubricate the joints and adjust the arm length if needed. Also ensure the wiper motor is generating sufficient torque. If the blade doesn’t stay flush against the windshield, it could be due to uneven mounting angles or bent components. Regular inspection and timely maintenance prevent most issues with marine wiper arms.
Can I replace a pendulum arm with a pantograph arm?
In many cases, yes — but you must ensure that the motor spindle and mounting configuration support pantograph movement. The W10/W12 Pantograph Arm requires a specific dual-arm mounting system, and your existing motor may need an upgrade or adapter. Measure your current sweep range and motor output torque before making the switch. Converting from pendulum to pantograph can significantly improve wiping quality, but it must be done with the right hardware to ensure safety and functionality. When in doubt, consult our experts for compatibility support.
Is the W10/W12 Pantograph Arm suitable for high-speed boats?
Yes, the W10/W12 Pantograph Arm is engineered for stability and pressure retention even at high speeds. Its dual-arm mechanism holds the blade firmly against the glass, reducing lift and streaking during fast navigation or wind exposure. It’s ideal for speedboats, cruisers, and offshore vessels that operate in open water. Combined with a robust wiper motor and marine-grade blade, this arm delivers consistent performance under dynamic sea conditions, making it a trusted solution among professional boat operators.
What’s the typical lifespan of a W10/W12 Pantograph Arm in marine conditions?
With proper maintenance, the W10/W12 Pantograph Arm can last several seasons. The corrosion-resistant finish and rugged construction help it withstand constant salt exposure, UV rays, and vibration. However, its lifespan depends on usage frequency, storage conditions, and the quality of maintenance. To maximize longevity, rinse with freshwater after every trip, lubricate quarterly, and replace blades regularly. Store your boat under cover when not in use to protect the arm from extended environmental wear. Following these best practices will ensure reliable operation for years.
Conclusion
The W10/W12 Pantograph Arm, 13-18″ (330-457mm) is a compact yet powerful marine-grade wiper arm engineered for maximum clarity and reliable operation. Whether you’re cruising offshore or fishing in shallow bays, this arm ensures that your visibility remains intact during storms and wet weather. With its dual-arm configuration, corrosion-resistant construction, and simple installation, it’s a must-have upgrade for serious boaters. Don’t compromise on safety—invest in a quality pantograph arm tailored for your vessel.
