Windshield Washers, Wipers & Replacement Motors

Clear Visibility on the Water Starts Here

When spray kicks up, rain rolls in, or fog settles over the bow, a reliable windshield wiper system is one of the most important safety components on any powerboat or cruiser. Unlike automotive wiper systems, marine windshield wipers, washers, and replacement motors are purpose-built to survive the demands of the water — saltwater corrosion, intense UV exposure, spray at speed, and wide temperature swings that would quickly degrade standard automotive components.

What's in This Category

This category covers the full spectrum of boat windshield visibility hardware, including:

• Wiper Motors — Waterproof and heavy-duty replacement motors designed for 12V or 24V marine electrical systems, available in standard and MRV styles with single- or two-speed operation.
• Wiper Arms — Adjustable pendulum and hook-style arms in stainless steel and powder-coated aluminum, sized to match your windshield geometry and sweep angle.
• Wiper Blades — Replacement blades in straight and articulating styles, built with UV-stable rubber and corrosion-resistant hardware to maintain clean, chatter-free sweeps.
• Windshield Washer Kits — Integrated washer systems that pair fluid delivery with your wiper motor for maximum helm clarity.
• Manual Wipers — Hand-operated alternatives that provide a dependable, motor-free option for smaller vessels or as a backup system.
• Synchronized Wiper Controllers — Multi-motor synchronizers that coordinate two or three wiper motors for wide windshields, adding interval speed settings and overload protection.

Why Marine Wipers Are Different

Marine wipers are engineered for saltwater corrosion resistance, high UV exposure, spray at speed, and wide temperature swings. Compared with 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. When shopping for a replacement motor or a complete wiper kit, it's important to match motor torque, sweep angle, and arm and blade reach to your windshield dimensions and operating conditions.

Top Brands for Marine Windshield Wipers & Washers

Sea-Dog Line is the dominant name in this category, offering one of the most comprehensive selections of marine wiper components available. Their lineup covers marine-grade windshield wiper arms, blades, motors, and more , including synchronized wiper controllers that can sync up to three motors and add an interval speed position to the traditional two-speed motor. From their hand-operated manual wipers with adjustable arms and 11" blades — an economical alternative to traditional wiper motors — to fully waterproof electric motors, all constructed of chrome-plated machined brass and stainless steel , Sea-Dog Line delivers durable solutions for a wide range of vessels.

Seachoice rounds out the category with a focused offering that delivers reliable performance at an accessible price point. Their self-parking windshield wiper kit is a popular all-in-one solution for boaters looking to install or upgrade a complete wiper system without sourcing individual components separately.

Shopping Tips

A boat wiper kit typically includes the wiper motor, arm, blade, mounting hardware, and a switch. Before purchasing, verify your motor's shaft diameter, maximum supported arm length, and available sweep angle settings. Use marine-grade materials — 316/304 stainless, anodized aluminum, UV-stable polymers — to ensure long service life against salt and UV exposure. Also don't overlook regular maintenance: rinse salt off components, clean blades, inspect for wear, and treat electrical connections against corrosion.
