The Marinco 34018S is an 18-inch deluxe stainless steel marine wiper blade that uses a silicone squeegee and multiple pressure claws to follow curved windshields for cleaner, streak-free wiping.
Built for boats and other marine craft where visibility and corrosion resistance matter, this wiper combines an all-stainless-steel frame with a marine-grade silicone wiping edge. The blade’s deluxe design distributes pressure across the full length of the squeegee so it maintains contact over curved glass surfaces. It’s sized for an 18-inch sweep and is engineered to resist rust and weathering in salty, wet environments.
The Marinco 34018S uses multiple flexible squeegee "claws" and a conforming silicone edge to maintain even contact with curved or flat glass. That even pressure reduces gaps and streaking that occur when a rigid blade hits bends or contours.
The frame and hardware are made entirely of stainless steel to resist rust and corrosion from saltwater and spray. Combined with a marine-grade silicone wiping edge, the blade stays functional longer than standard automotive materials when used on boats.
Performance depends on exposure and frequency of use, but routine replacement is recommended to keep wiping effective. Inspect the silicone edge for cuts, hardening, or uneven wear and replace as needed for optimal visibility.
The 34018S is an 18-inch (approx. 457 mm) blade intended for standard marine wiper arms; confirm arm attachment type and sweep length before ordering. Marinco offers a range of lengths and mounting styles to match common marine wiper spindles and arms.
Who this is for: The Marinco 34018S suits boat owners, captains, and marine maintenance pros who need a weather-resistant, corrosion-proof wiper for curved or flat windscreens. If you require a long-lasting blade that adapts to contoured glass and withstands saltwater exposure, this stainless steel frame with a marine silicone edge is engineered for that environment. It’s a practical choice for routine visibility maintenance on yachts, center consoles, cruiser cabins, and other watercraft where dependable wiping matters.
Q: Is the Marinco 34018S saltwater resistant?
