- Workboats and ferry boats
Its compatibility with the W25 motor series and multiple blade types allows this wiper arm to serve as a premium replacement or OEM-grade installation on demanding marine vessels. The arm is especially useful in wider bridge windows and windshields where a longer wiping reach is needed without compromising torque or accuracy.
How to Install W25 Pendulum Arm on Marine Vessels
Installing the W25 Pendulum Arm, 18-30″, Electropolished SS for marine is a straightforward process, but requires attention to detail for optimal performance. Here’s a step-by-step guide:
- Ensure the W25 wiper motor is powered off and disconnected.
- Align the arm’s base with the motor spindle and slide it onto the splined shaft.
- Secure it using the appropriate locking nut or clamp system provided.
- Adjust the telescopic arm to the desired length (18–30 inches) for proper windshield coverage.
- Tighten all fasteners and test the wiper action before final use.
Make sure the arm’s angle matches the blade geometry for complete sweep efficiency. Periodic inspection after installation ensures the arm remains tight and functional during marine operations.
Advantages of Electropolished Stainless Steel in Marine Wiper Arms
One of the standout features of the W25 Pendulum Arm for marine is its electropolished stainless steel finish. This not only provides a premium appearance but also enhances the surface resistance of the metal. Electropolishing removes surface impurities, scales, and embedded contaminants, resulting in a passive layer that offers exceptional protection against salt, acid, and harsh weathering.
Compared to brushed or untreated stainless steel, electropolished arms last longer, stay cleaner, and resist tea staining, rust spots, and discoloration—common issues faced in marine settings. This makes them a top choice for captains and engineers who demand performance and longevity.
Maintenance Tips
To maintain the optimal functionality and visual integrity of the W25 Pendulum Arm, 18-30″, Electropolished SS for marine, follow these simple maintenance practices:
- Rinse after exposure: Use fresh water to wash away salt deposits after every trip.
- Inspect joints and fasteners: Regularly check for loosening caused by vibration.
- Use marine-safe lubricant: Apply to moving parts every few months to prevent seizing.
- Avoid harsh chemicals: Clean with mild soap and soft cloth to preserve the polished finish.
Preventive maintenance not only extends the life of the pendulum arm but also improves its appearance and reliability over time.
Best Wiper Arm Options for Commercial Marine Applications
For commercial vessels, the W25 Pendulum Arm stands out for its adjustability, robust design, and sleek finish. Other options in the market may lack the precision or corrosion resistance required in challenging saltwater environments. If you’re searching for the best pendulum arm to pair with a high-torque motor like the W25, this electropolished version is your best bet.
Its longer adjustable range (18–30 inches) provides flexibility that many fixed-length arms simply can’t offer, and its superior finish makes it the go-to option for high-profile marine vessels where aesthetics matter alongside function.
Expert Advice and Pro Recommendations
Marine professionals consistently recommend the W25 Pendulum Arm, 18-30″, Electropolished SS due to its adaptability and strength. For vessels with extended windshields or operational demands in rough waters, the ability to adjust the wiper length and maintain a clean, reliable motion is invaluable.

Detailed FAQ Section
How do I know if the W25 Pendulum Arm fits my wiper system?
The W25 Pendulum Arm is designed to fit W25 wiper motors, which are typically used in heavy-duty marine applications. If your vessel is equipped with a W25 motor or equivalent torque class wiper system, this arm will be compatible. Ensure the motor spindle matches the splined or clamping base of the arm and that the blade type supports the width and range of motion provided by an 18-30” adjustable arm. Always confirm specifications with your manufacturer or supplier before purchase to avoid mismatches.
What makes electropolished stainless steel better for marine use?
Electropolishing is a finishing process that enhances the corrosion resistance of stainless steel by removing surface contaminants and creating a microscopically smooth finish. This reduces the likelihood of corrosion, scaling, and biofilm buildup, making it ideal for marine environments. Compared to mechanically polished or brushed stainless, electropolished steel maintains its shine longer and resists rust and pitting, even in saltwater exposure. This makes it perfect for components like the W25 Pendulum Arm, which are constantly exposed to moisture, salt, and UV rays.
Can I adjust the W25 arm length after installation?
Yes, the W25 Pendulum Arm features a telescoping design that allows for length adjustment even after installation. However, it is recommended to adjust the length prior to final tightening of the fasteners. To adjust, loosen the arm’s locking screw, extend or shorten to the desired length (between 18″ and 30″), and then retighten. This flexibility is especially useful when fine-tuning wiper coverage or adapting the arm for different blade sizes or windshield shapes.
How long does a W25 pendulum arm last in marine environments?
With proper maintenance, a W25 Pendulum Arm can last for many years—even in harsh saltwater conditions. The electropolished stainless steel resists corrosion far better than standard finishes. However, longevity depends on usage frequency, environmental exposure, and maintenance habits. Routine rinsing, occasional lubrication, and regular inspections will help extend the arm’s lifespan. On commercial boats, annual inspections and replacement every 3–5 years are recommended depending on wear and tear.
What should I do if the wiper arm starts skipping or making noise?
If your W25 Pendulum Arm begins to skip or make unusual noises, start by inspecting the blade itself—worn or hard rubber can cause friction. Next, check for secure attachment at the motor spindle and adjust any loose fittings. Also, ensure the arm is not overextended beyond its operational range. Apply marine-safe lubricant to the pivot joint and test the movement. If problems persist, check the wiper motor for torque loss. Addressing issues early can prevent motor strain and more expensive repairs down the line.
Conclusion
The W25 Pendulum Arm, 18-30″, Electropolished SS for marine delivers outstanding performance and durability for professional marine applications. Whether you command a commercial vessel or operate a luxury yacht, this wiper arm ensures clean visibility, reduced maintenance, and extended lifespan thanks to its corrosion-resistant, high-grade construction. Its adjustable length and universal fit make it a superior choice in both retrofit and OEM installations.
