A wiper system that streaks, stalls, or corrodes after a season of saltwater exposure is more than an inconvenience — on a yacht or cargo ship in heavy rain, a clear windshield is a safety requirement. This marine windshield wiper kit is built around 316 stainless steel components and dual-shaft motors in 35W and 50W configurations, available as complete matched sets or individual replacement parts so you can outfit a new build or repair an existing system without buying more than you need.
Each variant is sold as a single unit or set as described. The system covers every major component: a 35W copper-shaft motor (suited for windshields up to approximately 1 meter / 39") or 50W motor (for windshields over 1 meter / 39"), available in 12V and 24V. Wiper blades are manufactured from 316 stainless steel in six lengths — 300mm (12"), 350mm (14"), 400mm (16"), 450mm (18"), 500mm (20"), 550mm (22"), and 600mm (24"). Double wiper arms are available in 450–600mm range, with or without an integrated washer nozzle. Control switches are available as single or dual configurations. Complete yacht stainless steel sets bundle motor, arm, blade, and hardware in 12V or 24V, with or without water spray. Cargo ship external wiper sets are available in 24V with or without spray.
This kit is well suited for replacing a corroded or failed wiper system on a sailing yacht or motorboat, building a new windshield wiper installation on a custom vessel or commercial fishing boat, and upgrading an existing cargo ship wheelhouse wiper to a 24V external system with washer capability — anywhere a durable, saltwater-resistant marine wiper system needs to perform reliably in all weather.

The 35W dual-shaft motor is generally suited for windshields up to approximately 1 meter (39 inches) wide. The 50W dual-shaft motor is designed for larger windshields over 1 meter wide, providing more torque to sweep a longer blade across a wider glass surface. If your windshield is borderline, choose the higher-wattage motor for reliable performance in all weather conditions.
Blade length should match the sweep arc of your wiper arm and the width of your windshield. Available lengths are 300mm (12"), 350mm (14"), 400mm (16"), 450mm (18"), 500mm (20"), 550mm (22"), and 600mm (24"). Measure the effective wipe area on your windshield and select the blade that covers it without overreaching the glass edge.
The complete yacht stainless steel sets include the motor, wiper arm, blade, and mounting hardware as a matched system — ideal for new installations or full replacements. Individual components (motor, blade, arm, switch) are available separately for repairs, upgrades, or custom builds where only one part needs replacing.
Yes. Grade 316 stainless steel contains molybdenum, which provides significantly better resistance to chloride and saltwater corrosion than 304 SS. It is the standard material for marine hardware exposed to spray, splash, and sea air. The wiper blades and arms in this kit are manufactured from 316 SS for long-term durability in saltwater environments.
Motors and complete sets are available in both 12V and 24V configurations. Select the voltage that matches your vessel’s electrical system. Yachts and smaller sailboats typically run 12V systems, while larger commercial vessels and cargo ships generally use 24V systems. Confirm your vessel’s system voltage before ordering.
Sets and wiper arms with the water spray option include a washer nozzle integrated into the wiper arm, allowing you to spray cleaning fluid onto the windshield while wiping. This is useful for removing salt residue, bird droppings, and other debris that dry wiping alone cannot clear. The nozzle connects to a separate washer fluid reservoir (not included).
Yes. The 24V external wiper variants are specifically designed for cargo ships and larger commercial vessels, featuring an external mounting configuration suited to heavy-duty wheelhouse windshields. These are available with or without the water spray option. For yacht and sailboat applications, the yacht full stainless steel sets are the appropriate choice.
