Overview / What Is the W10/W12 Pendulum Arm, 18-24″?
The W10/W12 Pendulum Arm, 18-24″, Adj Tip is a marine wiper arm engineered to fit W10 and W12 style motors. It is used in pendulum-style wiper systems and features an adjustable tip that improves blade contact and sweep accuracy. Its adjustable length (18-24 inches) provides versatility for different boat windshield sizes and designs, ensuring effective coverage and cleaning in every condition.
This arm is constructed from marine-grade stainless steel or anti-corrosive coated materials. It is ideal for use on vessels that frequently face salt spray, UV radiation, rain, and environmental exposure. The adjustable tip makes it suitable for curved or angled windshields, enhancing its range of compatibility and performance.
Benefits of Using Adjustable Wiper Arms on Marine Vessels
One of the standout features of the W10/W12 Pendulum Arm is its adjustable length and tip. Here’s why adjustability matters in marine environments:
- Better Visibility: Customizing the sweep area allows for better coverage and clearer vision in all weather.
- Blade Compatibility: Adjustable arms accommodate different blade lengths and mounting positions.
- Easier Maintenance: You can fine-tune blade tension and angle for reduced wear and longer life.
- Increased Safety: Consistent, wide-angle wiping improves navigation visibility, especially in storms.
With traditional fixed arms, you’re limited by preset lengths and angles. The adjustable W10/W12 arm, on the other hand, offers flexibility and adaptability—a vital requirement for modern marine applications.
How to Install W10/W12 Pendulum Arm, 18-24″
Proper installation is essential for optimal performance. Here’s a step-by-step guide on how to install the W10/W12 Pendulum Arm:
- Turn off the system: Disconnect the wiper motor power before beginning.
- Remove old arm: If replacing an arm, detach it by loosening the central mounting bolt or nut.
- Align the new arm: Position the pendulum arm onto the wiper motor shaft. Match splines or fitment grooves accordingly.
- Tighten the fastener: Secure the arm firmly using marine-grade hardware. Avoid over-tightening.
- Adjust length and tip: Extend the arm to the desired length and fine-tune the tip angle for optimal sweep coverage.
- Test run: Restore power and check arm motion and blade contact. Make final adjustments as needed.
Installation can be done in under 30 minutes with basic tools. Always refer to your vessel’s manual or the wiper motor’s installation guidelines for torque specs and compatibility information.
Understanding W10 vs W12 Compatibility
The W10 and W12 designations refer to the size and torque handling of the wiper motor the arm connects to. Here’s how to choose the correct one:
- W10: Suited for small to mid-sized boats with lighter blade requirements.
- W12: Best for larger vessels and heavier-duty windshield wiping systems.
Both arms feature similar adjustment capabilities, but the base connection and torque compatibility vary slightly. Confirm the motor type on your boat before purchase to ensure seamless fitment and operation.
Maintenance Tips
Regular maintenance of your W10/W12 Pendulum Arm, 18-24″, ensures longevity and performance. Follow these simple guidelines:
- Rinse arm with fresh water after saltwater exposure.
- Check for signs of rust or corrosion every few months.
- Inspect the adjustable tip for tightness and secure positioning.
- Use marine-safe lubricants on pivot points twice per year.
- Replace blades periodically to prevent excessive strain on the arm.
Preventative care significantly reduces the risk of failure and keeps your visibility clear during critical navigation moments.
Best Use Cases for W10/W12 Pendulum Arm

Detailed FAQ Section
What makes the W10/W12 Pendulum Arm ideal for marine use?
The W10/W12 Pendulum Arm is built from corrosion-resistant materials that can handle constant exposure to salt, moisture, and UV radiation. The adjustable tip provides a tailored fit, ensuring optimal blade contact with the windshield surface, which is vital during storms or foggy conditions. Its rugged construction supports long-term reliability on everything from fishing boats to luxury yachts. When compared to automotive-grade arms, marine pendulum arms like the W10/W12 provide better sealing, higher torque resistance, and are tailored to meet the demands of marine navigation systems.
Can I install the W10/W12 Pendulum Arm, 18-24″ myself?
Yes, installation is straightforward and can typically be completed in under 30 minutes with basic hand tools. You will need to align the arm to the wiper motor shaft, secure it with a bolt or nut, and adjust the length and tip angle. It is important to ensure the blade makes consistent contact across the sweep range. The installation process does not require specialized tools, although care must be taken to avoid over-tightening. For best results, consult your boat’s manual or reach out to the supplier for installation guidance.
How often should I replace or service the pendulum wiper arm?
While the W10/W12 Pendulum Arm is built for durability, it should be inspected at least once every 6 months. If your boat operates in saltwater, a quarterly inspection is ideal. You should look for signs of corrosion, joint looseness, or improper blade angle. If the arm is difficult to move manually or you notice skipping during operation, servicing or replacement may be necessary. Cleaning, lubricating joints, and checking fasteners can help extend its life significantly.
How do I adjust the tip of the arm correctly?
To adjust the tip, you typically loosen the set screw or bolt at the tip joint, reposition the blade mount to achieve the correct angle and blade pressure, and re-tighten securely. This allows the blade to make complete, even contact with the windshield. Proper tip adjustment is critical in avoiding chatter or partial wiping during operation. The goal is a smooth, consistent wipe that follows the windshield curve. If unsure, test with a dry run before use in actual marine conditions.
Is the W10/W12 Pendulum Arm compatible with all marine wiper motors?
The W10/W12 Pendulum Arm is compatible specifically with W10 and W12 class marine wiper motors. These are standard classifications used by several marine wiper motor manufacturers. Always check your existing motor’s shaft size and compatibility specs. If your boat uses a different class, such as W38 or W50, you’ll need the appropriate arm model. Contact All Boat Supplies for confirmation if unsure about compatibility.
