Marinco Wiper Arm Deluxe Stainless Steel - Black - Single - 18"-24"

The Marinco Wiper Arm Deluxe Stainless Steel is a heavy-duty marine wiper arm engineered for 18-to-24-inch blade applications on both standard and heavy-duty wiper motors. Constructed from corrosion-resistant stainless steel with a black finish, this single wiper arm delivers the articulating bend-back feature that allows the blade to flex away from the windshield during manual override or emergency situations—a critical safety mechanism for coastal and offshore marine environments where salt spray and extended exposure demand reliable hardware.

The motor shaft mounting assembly includes an additional set screw clamping mechanism that ensures secure fastening and resists vibration-induced loosening common on vessels operating in rough water conditions. This design provides superior hold compared to standard single-screw mounts. The arm is compatible with Marinco's 2.5, 1.5, 1000, and MRV series wiper motors, making it a direct replacement for many modern and older marine wiper systems. The dry single wiper configuration is optimized for cabin and hardtop window clearing without the added complexity of dual-arm setups.

This wiper arm is built for working boat owners, charter operators, and marine technicians who prioritize reliability in salt-air environments. Whether you're replacing a corroded or damaged arm on a center console, trawler, or cabin cruiser, the stainless steel construction and proven Marinco engineering deliver long service life with minimal maintenance. The 18-to-24-inch adjustable range accommodates varying windshield geometries found across different vessel types and models.

Part number 33070A is the OEM specification for this deluxe-class arm, preferred by marine dealers and aftermarket suppliers for quality restoration and repair applications across the recreational and commercial marine sector.
