Marinco Deluxe Stainless Steel Wiper Arm — Adjustable 10"–14" Single Marine Arm, Corrosion-Resistant

The Marinco 33007A Deluxe Stainless Steel Wiper Arm is a single, adjustable 10"–14" marine-grade arm designed to replace or upgrade windshield wipers on boats and recreational craft.

Built to resist corrosion and provide a streamlined wipe, this Marinco wiper arm offers a durable stainless-steel construction and a slim profile that fits many marine windshield systems. It ships as a single arm sized to adjust between 10" and 14", making it a versatile option for owners needing a direct replacement or a sturdier upgrade than basic plated arms. Lightweight and compact in its packaging, the unit is manufactured in China and arrives ready for installation with common mounting hardware (sold separately depending on your wiper motor and blade fitting).

What makes this wiper arm suitable for marine use?

The 33007A is made from stainless steel to better withstand salty air and humid conditions than plain steel alternatives. Its polished finish reduces surface corrosion while maintaining a low-profile appearance that matches most boat dashboards and cowlings.

• Stainless-steel body for improved corrosion resistance
• Polished finish for lower maintenance and cleaner look
• Single-arm design compatible with common marine wiper motors
• Compact packaging: 32.512 x 6.096 x 2.032 cm dimensions, 0.45 lb weight

How do I know if the 10"–14" size will fit my boat?

The arm’s adjustable span covers blades that measure roughly 10" to 14" when installed, so measure the swept arc of your current wiper blade or the windshield section you need covered. Confirm that the mating end and motor spline on your boat match the replacement arm or that an adapter is available for your motor type.

• Adjustable length accommodates a range of blade sizes (10"–14")
• Measure current blade sweep before ordering to ensure coverage
• Check motor spline and connector compatibility or adapter needs

How easy is installation and maintenance?

Installation is straightforward for anyone familiar with marine wiper systems: remove the old arm, confirm fit with the motor shaft, and secure the new arm with the appropriate fastener. Routine maintenance is minimal — wipe down and inspect the finish and fasteners periodically to keep the arm performing reliably in marine conditions.

• Standard removal and replacement procedure fits common wiper setups
• Periodic inspection and cleaning recommended for long life
• Lightweight 0.45 lb helps simplify handling and alignment

Who is this for? The Marinco 33007A Deluxe Stainless Steel Wiper Arm is ideal for boat owners, marinas, and repair shops looking for a corrosion-resistant, adjustable single arm to replace worn or damaged wiper arms. It suits owners who want a tidy, low-maintenance upgrade for smaller windshields or for vessels that need a dependable, space-saving wiper solution without changing their existing motor or blade system.
