Windshield Washers, Wipers & Replacement Motors

Clear Visibility on the Water Starts with the Right Wiper System

Whether you're navigating a squall offshore or motoring through early-morning fog, a reliable windshield wiper system is one of the most critical—and most overlooked—pieces of safety equipment on any boat or RV. Marine and RV windshield wipers, washers, and replacement motors are purpose-built for conditions that would destroy a standard automotive unit: relentless UV exposure, saltwater spray, wide temperature swings, and constant moisture. Cutting corners here can mean zero visibility exactly when you need it most.

How Marine Wiper Systems Differ from Automotive

Marine wipers are engineered for saltwater corrosion resistance, high UV exposure, spray at speed, and wide temperature swings. Unlike automotive systems, marine wipers use stainless steel, anodized aluminum, and UV-stabilized polymers in motors, arms, and blades to prevent seizure and degradation over time. A complete system typically consists of four key components working in concert: the motor, the wiper arm, the blade, and the mounting hardware or switch.

A boat wiper kit typically includes the wiper motor, arm, blade, mounting hardware, and a switch (single or two-speed). Matching components by shaft diameter, sweep angle, and maximum arm/blade length ensures full, chatter-free coverage in the primary sightline.

What to Look for When Shopping

• Interior vs. Exterior Motors: Two-speed, self-parking heavy-duty motors are available for both interior/protected and exterior/unprotected locations. Make sure you choose the right type for your installation.
• IP Rating & Waterproofing: An IP66 rating means a motor is dust-tight and protected from strong jets of water —essential for open-cockpit boats and exposed helm stations.
• Sweep Angle Adjustability: Sweep angle is typically preset at 80° or 110°, but can often be reset to a range of angles to match your specific windshield geometry and helm sightlines.
• Materials: Use marine-grade materials such as 316/304 stainless, anodized aluminum, and UV-stable polymers for salt and UV exposure.
• Coast-to-Park Feature: All quality wiper motors include a "coast-to-park" feature, which means that when power is cut, the motor will coast to its original set position at the bottom or top of the windshield.
