Sea-Dog Line Windshield Wiper Blades & Arms
Sea-Dog Line Marine Windshield Wiper Blades & Arms
When visibility on the water is on the line, the quality of your wiper system matters as much as any other piece of safety equipment aboard. Sea-Dog Line has built a well-earned reputation in the marine hardware world, and their lineup of windshield wiper blades and arms reflects the same commitment to durability and broad compatibility that captains rely on across all kinds of vessels.
Built for the Marine Environment
Unlike automotive wiper components, marine wiper systems must endure relentless exposure to saltwater spray, UV radiation, ozone, and wide temperature swings. Marine wipers are engineered for saltwater corrosion resistance, high UV exposure, spray at speed, and wide temperature swings — and compared with automotive systems, they rely on stainless steel, anodized aluminum, and UV-stabilized polymers to prevent seizure and degradation over time.
Sea-Dog Line answers these demands head-on. Their deluxe curved wiper blades feature a marine-grade silicone rubber squeegee, are designed for use on flat or curved windshields with a straight blade-style arm, and are constructed of corrosion-resistant 304 stainless steel. This combination of materials is a hallmark of Sea-Dog's approach: purpose-built for the sea, not adapted from a land-vehicle spec.
A Range of Arm & Blade Styles
Sea-Dog Line offers wiper components to cover a wide spectrum of boats and motor configurations. All current Sea-Dog wipers now come equipped with the new slip-on, hinge-style wiper blades and arms , representing their modern standard. For older installations, stamped 304 stainless steel and Lexan blade hook-style arms are available as replacements for Sea-Dog wipers sold prior to 1993, and they also fit most older wipers sold by AFI, Wilcox, NA Taylor, GEM, L.S. Brown, and others. This makes Sea-Dog an exceptional choice for restoring vintage boats or sourcing hard-to-find replacement components.
On the arm side, Sea-Dog's Adjustable Pantographic Wiper Arm features an adjustable J-Hook (automotive-style) design that fits all standard MRV and heavy-duty waterproof wiper motors with a 5/8" shaft diameter, and is compatible with multiple offset sizes. For a more traditional fit, adjustable wiper arms for use on MRV and heavy-duty waterproof wiper motors with a 5/8" shaft diameter round out the arm lineup, giving boaters the flexibility to match their existing motor configuration.
For those who prefer or need a non-powered option, Sea-Dog offers a manual windshield wiper that includes an 8"–12" adjustable wiper arm and an 11" blade — a hand-operated unit that serves as an economical alternative to traditional wiper motors, constructed of chrome-plated machined brass and stainless steel.
Cross-Compatibility & Legacy Support
Sea-Dog Line supplies both legacy and current styles for cross-compatibility , making them one of the few manufacturers that truly bridges the gap between older and newer marine wiper systems. Whether you're doing a like-for-like blade swap or upgrading an entire arm assembly, Sea-Dog's lineup is designed to integrate seamlessly with the motors and mounting hardware already on your boat.
With 13 products spanning blades and arms in both black and silver finishes, and in multiple lengths to suit different windshield spans, Sea-Dog Line's wiper catalog is a practical, reliable resource for any boater maintaining helm visibility.
