How to Install the W25 Pantograph Arm for Marine Applications
If you’re wondering how to install the W25 pantograph arm, rest assured that it’s a straightforward process with the right tools. Begin by identifying the correct mounting location and wiper motor shaft—most commonly 16mm diameter. Position the pantograph arm so the base aligns with the motor shaft and secure it using the built-in set screw or locking mechanism. Ensure the arm is mounted at the proper angle and has enough clearance for full sweep operation.
Next, attach the secondary arm to the main arm link using the provided hardware. Connect the wiper blade and adjust the length as necessary. Turn on the motor to verify that the sweep path is clear and that the blade maintains contact with the windshield. Adjust the angle or linkage if the motion seems uneven. Proper alignment ensures optimal wiping and minimizes blade chatter.

What makes electropolished stainless steel ideal for marine use?
Electropolishing is a finishing process that removes surface impurities and enhances corrosion resistance. For marine environments, where salt spray and moisture are constant, electropolished stainless steel prevents rust, pitting, and degradation much better than standard brushed or untreated steel. This finish also makes the surface smoother, reducing friction between moving components. In the case of the W25 Pantograph Arm, this means smoother operation, less maintenance, and longer lifespan—making it the best material choice for heavy-duty marine applications.
Can the W25 Pantograph Arm be used on any boat?
While the W25 Pantograph Arm is compatible with most large boats and commercial vessels, it is best suited for those equipped with compatible wiper motors like the W25 series. The arm is designed to handle heavy-duty wiping and longer blades, so it’s ideal for large windshields and tougher marine conditions. For smaller boats or standard wiper motors, it may be overkill or incompatible due to size and torque requirements. Always verify compatibility based on shaft diameter (usually 16mm) and torque output of your motor before installation.
What are the most common problems with pantograph arms?
The most common issues with pantograph arms include misalignment, wear on the linkage, and motor incompatibility. If the blade wipes unevenly or skips, check the alignment between the primary and secondary arms. Linkage joints can loosen over time, leading to noisy or uneven movement. Ensure all fasteners are torqued to spec and that the motor delivers sufficient torque to operate the arm and blade size. Also, replace the wiper blades seasonally to avoid uneven streaks or chatter during operation.
How long does the W25 Pantograph Arm last under normal marine use?
With proper care and regular maintenance, the W25 Pantograph Arm can last several years—even in harsh marine environments. Thanks to its electropolished stainless steel construction, it resists corrosion and surface fatigue better than traditional arms. Most users report multi-season reliability without the need for major repairs. Its rugged design makes it ideal for both seasonal recreational users and year-round commercial operations. Regular rinsing, lubrication, and inspections will keep the arm in optimal condition for years to come.
