Detailed FAQ Section
What materials are used in the W38 wiper arm?
The W38 wiper arm is typically made from high-quality stainless steel or powder-coated materials. Electropolished stainless steel is highly favored for its resistance to corrosion in harsh marine environments, while the black powder-coated variant provides a sleek, non-glare finish. These materials are chosen specifically for marine durability, ensuring the arm maintains its structural integrity even after years of saltwater exposure.
Can I adjust the length of the W38 wiper arm myself?
Yes, the W38 wiper arm is fully adjustable between 24 and 35 inches (609mm to 900mm). You can manually extend or shorten the arm by loosening the adjustment bolt, sliding the arm to the desired length, and retightening it. This feature makes it ideal for various windshield sizes, accommodating multiple vessel types, from cabin cruisers to sailing yachts. Always ensure the arm is securely fastened after adjustment to prevent slippage.
How do I know if the W38 wiper arm fits my motor?
Compatibility depends on the shaft size and spline type of your wiper motor. The W38 arm is compatible with most standard marine wiper motors, especially those within the 12V–24V range used in helm systems. To verify, measure your motor shaft diameter and count the splines. Consult your motor’s technical sheet or speak with marine part suppliers like All Boat Supplies for a compatibility check.
What are the signs I need to replace my wiper arm?
Key signs include wobbling during operation, visible corrosion, reduced blade pressure on the windshield, or blade skipping. If your wiper arm no longer maintains firm blade-to-glass contact or shows excessive flexing, it’s time to replace it. Regular inspection every boating season is recommended to catch these issues early and avoid visibility problems during adverse weather.
Are there any maintenance products I should use with this arm?
Yes. Using marine-grade lubricants on the pivot points can prolong arm performance. Cleaning with fresh water and applying a UV protectant can also help. Avoid using harsh chemicals that could degrade the coating. For blade maintenance, always use rubber-safe cleaners and change blades every 6–12 months depending on use frequency.
