Sea-Dog Deluxe Curved Wiper Blade, 18 in. – Black
A dependable 18-inch wiper blade built for the marine environment. The Sea-Dog Deluxe Curved Wiper Blade is constructed from 304 stainless steel with a black powder-coat finish and fitted with a marine-grade silicone rubber squeegee that delivers a clean, streak-free wipe on both flat and curved windshield surfaces. At 18 inches, it’s the most common blade size for single-motor wiper setups and pairs directly with the Marinco 1000 motor at its rated maximum arm and blade combination.
The curved blade profile maintains consistent contact pressure across the full sweep arc, eliminating the skipping or streaking that a straight blade can produce on a curved windshield. Silicone rubber resists UV degradation, ozone cracking, and salt exposure far better than standard rubber, keeping the squeegee pliable and effective longer between replacements. The black finish blends cleanly with dark-framed windshields and hardware. Compatible with straight blade-style wiper arms.

Parts Desk Insights
Best suited for single-motor wiper setups where the Marinco 1000 motor is the power source — the 18 in. blade is the maximum rated size for that motor at sweep angles of 80° or less. The black finish is a popular choice on boats with dark windshield frames, black hardware, or a blacked-out aesthetic. The curved silicone blade is a strong choice when the windshield has any curve to it, maintaining edge-to-edge contact that a straight blade would lose.
