Sea-Dog Line Marine Windshield Wipers, Washers & Replacement Motors

Clear visibility at the helm isn't a luxury — it's a fundamental safety requirement. Sea-Dog Line, a company with roots going back to the early 1930s on the Pacific Coast, has spent decades engineering marine hardware that holds up in the harshest saltwater environments. Their line of windshield washers, wipers, and replacement motors reflects that same commitment: purpose-built for boats, designed to resist corrosion, and engineered to keep working long after automotive-grade alternatives would have failed.

A Lineup Built for the Marine Environment

Sea-Dog's wiper products span the full system — from manual hand wipers to multi-speed electric motors, wiper arms, blades, synchronizer controllers, and complete wiper kits. Each component is selected with marine conditions in mind. The brand's wiper motor housings use powder-coated aluminum construction with stainless steel mounting brackets, shafts, and knurled fittings — materials chosen specifically to resist the combination of salt spray, UV exposure, and wide temperature swings that can destroy lesser hardware.

Sea-Dog produces wiper systems in two core motor configurations: the Standard Wiper Motor and the Waterproof Heavy-Duty Wiper Motor. The standard motor kit is designed around a corrosion-proof aluminum case with a stainless steel base plate and adjustable sweep settings of 80° or 110° — and can power arm-and-blade combinations up to 14 inches. The heavy-duty waterproof motor steps things up considerably, carrying an IP66 rating (dust-tight and protected from strong water jets), CE approval, and the ability to power arm-and-blade configurations up to 24 inches. Both motors feature Sea-Dog's "coast-to-park" function, which automatically returns the wiper arm to its set resting position when power is cut — a refinement that prevents the blade from freezing mid-sweep and blocking sightlines.

Sweep, Park, and Fit — All Adjustable

One of the practical strengths of Sea-Dog's wiper motors is their adjustability. Sweep angle can be preset or reconfigured to match the geometry of virtually any windshield, with options spanning 40°, 50°, 60°, 70°, 80°, 90°, and 110°. Park direction — right-hand or left-hand — is also user-configurable, accommodating the wide variety of helm layouts found across powerboats, cruisers, and commercial vessels alike.

For arms and blades, Sea-Dog supplies both legacy hook-style connections and newer slip-on hinge designs, maintaining compatibility with common 3/8-inch motor shafts. This cross-compatibility makes Sea-Dog an especially practical choice when replacing worn components in an existing wiper system without needing to overhaul the entire setup.

Material Quality That Matches the Marine Standard

Across their wiper lineup, Sea-Dog draws on the same material philosophy that defines their broader hardware catalog. Wiper arms feature stamped 304 stainless steel construction, blades use Lexan and UV-stable materials, and manual hand wiper options are machined from chrome-plated brass — a classic marine material valued for its corrosion resistance and clean appearance at the helm. The manual windshield wiper, in particular, remains a practical choice for smaller vessels or as a backup system on larger ones.

Whether you're doing a straightforward blade replacement, swapping out a failed motor, or building a complete two-speed synchronized wiper system from scratch, Sea-Dog Line offers the components to complete the job with marine-grade confidence.
