W25 Pantograph Arm, 18-30″ (457-762mm)
Introduction
Ensuring maximum visibility at sea is not a luxury—it’s a necessity. Marine-grade wiper systems play a critical role in navigation safety, and at the heart of these systems lies a key component: the wiper arm. The W25 Pantograph Arm, 18-30″ (457-762mm) for Boats & Marine Engines is engineered to deliver exceptional performance and reliability under the most demanding marine conditions. Designed for a broad range of vessel types, from commercial craft to luxury yachts, this adjustable pantograph arm ensures full windshield coverage and consistent wiper pressure.
Built with high-quality, corrosion-resistant materials, the W25 pantograph arm is a durable choice for long-term use in saltwater environments. Its extended reach and dual-arm support ensure smooth operation and optimal visibility in rain, sea spray, and fog. Whether upgrading your current setup or outfitting a new vessel, this arm is a trusted solution for any marine wiper system powered by compatible W25 motors.
Overview / What Is W25 Pantograph Arm, 18-30″ (457-762mm)?
The W25 Pantograph Arm is a robust, adjustable-length marine wiper arm designed to operate in a parallel movement pattern. Unlike pendulum arms that sweep in a singular arc, the pantograph configuration uses a dual-arm setup to move the blade evenly across the windshield. This results in enhanced wipe coverage, consistent pressure, and greater visibility across wide or curved marine glass surfaces.
Adjustable between 18″ to 30″ (457-762mm), the W25 Pantograph Arm is compatible with W25 marine wiper motors and blades. It features marine-grade materials with a black powder-coated or stainless finish, depending on the model, providing excellent protection against corrosion, UV exposure, and mechanical wear.

How to Install W25 Pantograph Arm, 18-30″
Installing the W25 Pantograph Arm is straightforward and requires only basic tools. Follow these steps for a successful installation:
- Prepare the Wiper Motor: Ensure your W25 motor is installed and functional. Turn off the power to the motor before beginning.
- Mount Primary Arm: Attach the arm to the wiper motor spindle. Align it parallel to the bottom of the windshield at rest.
- Attach Secondary Arm: Connect the second arm to the fixed point on the primary arm using the provided joint connector.
- Adjust Arm Length: Use the set screw or adjustment knob to set the length between 18″ to 30″, depending on your windshield size.
- Install Wiper Blade: Attach the wiper blade using the included locking mechanism. Ensure the blade sits flush with the glass.
- Test the Operation: Turn on the wiper motor and observe the motion. Ensure full range and no obstruction.
For best results, always follow the manufacturer’s guidelines and consult the vessel’s manual for optimal arm positioning and motor calibration.
Why Choose a Pantograph Arm Over a Pendulum Arm?
Pantograph arms are increasingly favored for larger marine windshields due to their ability to provide uniform pressure and extended coverage. While pendulum arms swing in a fixed arc from a single pivot, pantograph arms use two pivot points to guide the wiper blade in a straight path across the glass. This design ensures that the blade stays perpendicular to the glass surface, improving wipe efficiency and reducing streaks.
In high-speed marine environments or heavy rainfall, pantograph arms reduce mechanical strain and improve blade contact. For boats with wide or dual-pane windshields, this type of arm is practically essential. It also provides better durability over time, as the load is shared between two points instead of one.
Understanding the Cost and Durability of Pantograph Arms
Investing in a quality marine wiper arm like the W25 may seem costly upfront, but its durability and long-term performance outweigh the initial expense. These arms are designed to last through years of constant saltwater exposure, rough weather, and high motor usage.
The W25 Pantograph Arm offers an excellent balance between price and performance, especially considering its stainless steel or corrosion-resistant coated options. With proper care and occasional blade replacement, this arm can remain functional for 3–5 years or more. It’s a smart investment for professional mariners and leisure boaters alike.
Maintenance Tips
Maintaining your W25 Pantograph Arm ensures optimal performance and extends its service life. Here are essential maintenance practices:
- Freshwater Rinse: After each voyage, rinse the arm and blade with clean water to remove salt, grime, and debris.
- Lubricate Pivot Points: Every 2–3 months, apply marine-grade lubricant to the arm’s joints and pivots to reduce wear.
- Inspect Screws and Joints: Check for loose screws or joint fatigue, especially after navigating rough seas.
- Replace Wiper Blades: Use compatible blades and replace them every 6–12 months for optimal wiping efficiency.
- Protect Against UV: When not in use, cover the wiper system with a UV-resistant tarp or screen to prevent sun damage.
Routine inspection and cleaning go a long way in preserving the efficiency and aesthetics of your marine wiper system.

Detailed FAQ Section
What makes the W25 Pantograph Arm ideal for marine use?
The W25 Pantograph Arm is specifically engineered for marine environments, featuring materials that resist corrosion from saltwater, UV rays, and weather exposure. Its pantograph design ensures that the wiper blade maintains constant contact with the glass, providing a clean, streak-free wipe even in the harshest conditions. The adjustable length from 18 to 30 inches makes it suitable for a wide range of boat windshields, and its compatibility with W25 wiper motors makes installation quick and secure. Overall, its durability, range, and efficiency make it a trusted choice among marine professionals.
Can I install the W25 Pantograph Arm without professional help?
Yes, the W25 Pantograph Arm is designed for easy DIY installation using standard hand tools. However, you should always follow the installation guide provided with your wiper motor and arm. Installation typically involves mounting the arm onto the motor shaft, adjusting the length to match your windshield dimensions, and securing all components firmly. Testing the range of motion post-installation is crucial to ensure it doesn’t overextend or collide with surrounding structures. For complex vessels or when replacing a different type of arm, you may consider professional installation for optimal results.
How do I know when to replace the W25 Pantograph Arm?
Like any mechanical component, the pantograph arm will wear over time. Signs that it’s time to replace include wobbling, uneven blade pressure, rust buildup, and reduced wipe efficiency. If you notice streaks during operation despite having a new blade, the arm may have developed joint wear or alignment issues. Regular inspections can help identify early signs of wear. As a general rule, marine wiper arms should be evaluated annually and replaced every 3–5 years depending on usage and environmental exposure.
Is the W25 Pantograph Arm compatible with other motor brands?
The W25 Pantograph Arm is optimized for use with W25 series marine wiper motors. While it may physically fit other motor types with similar spindle dimensions, performance and compatibility are not guaranteed. It is always recommended to match the arm with the specified motor series to ensure optimal performance, safety, and warranty coverage. If you’re unsure whether your motor is compatible, reach out to All Boat Supplies for guidance before purchasing.
What type of wiper blades should I use with the W25 Pantograph Arm?
Use marine-grade wiper blades that are UV-resistant and compatible with the connector style of the W25 Pantograph Arm. Silicone or neoprene rubber blades are recommended due to their resistance to saltwater and sunlight. Standard marine wiper blades in the range of 18″ to 30″ typically work well with the W25 arm. Always verify the blade attachment system (hook, pin, or bayonet) matches the arm to ensure a secure fit. Proper blade selection enhances the overall performance and extends the life of both the arm and the motor.
