Marinco Wiper Arm Deluxe Stainless Steel Single - 14"-20"

The Marinco Wiper Arm Deluxe Stainless Steel Single 14"-20" is a marine-grade articulating wiper arm designed for use with standard and heavy-duty marine wiper motors. Built entirely from stainless steel, this arm delivers the corrosion resistance required in saltwater and freshwater environments where typical painted or plated arms fail prematurely. The model 33010A accommodates arm lengths between 14 and 20 inches, making it suitable for a wide range of vessel windscreen configurations.

This deluxe-grade arm incorporates two critical engineering features that distinguish it from economy wiper arms. The articulating or bend-back design allows the blade to flex away from the windscreen when the wiper reaches the end of its stroke, preventing strain on the motor and extending its service life. The motor shaft mounting system includes an additional set screw for enhanced clamping security—essential when operating in rough seas where vibration and shock loads are constant. The arm is compatible with Marinco's 2.5, 1.5, 1000, and MRV wiper motor models, operating in a dry single wiper configuration ideal for compact wheelhouse installations or single-pass wiping scenarios.

Marine operators and boat maintenance technicians choose this arm when replacing worn equipment on fishing vessels, commercial workboats, and cruising sailboats where motor longevity and reliable visibility are non-negotiable. Weighing just 0.55 lbs and measuring 18 inches in overall length, it installs with minimal weight penalty while delivering the structural integrity needed for repeated high-speed wiping cycles in harsh marine conditions. Stainless steel construction eliminates the need for frequent corrosion treatment, reducing maintenance labor and extending the service interval between component replacements.
