Marine Dual Drive Windshield Wiper Motors

Heavy‑duty Marine Dual Drive windshield wiper motors engineered for large pantograph systems and extreme marine conditions. A single high‑torque motor drives both pivots simultaneously, evenly distributing loads for long‑term reliability on commercial and offshore vessels.

What Is a Marine Dual Drive Motor

Marine Dual Drive motors are designed for large arm and blade configurations where standard single‑pivot motors are not sufficient. One motor powers two synchronized pivots, reducing stress on arms, blades, and linkages while maintaining consistent wiping performance in rough seas.

Key characteristics:

• Optimized for pantograph wiper systems
• Load shared across both drive pivots
• Recommended for arm or blade lengths exceeding 32 inches / 800 mm

Key Applications

Typical installations include:

• Commercial vessels
• Ferries and passenger boats
• Workboats and tugboats
• Offshore and utility craft
• Large wheelhouses and pilothouses

Dual Drive Configuration Requirements

Marine Dual Drive systems require additional hydraulic-style fittings to link both pivots:

Required components (sold separately):

• Tee connector
• In‑line connector
• Bulkhead fitting

These components allow the single motor to drive both pivots evenly and should be selected based on installation layout.

Arm & Blade Compatibility

• Designed for pantograph wiper systems
• Compatible with stainless steel pantograph arms
• Arms are supplied dry by default
• Wet arm kits are available separately when washer integration is required

Proper system matching of motor, arm length, and blade length is critical for performance and longevity.

Important Notes

• Dual Drive motors are recommended whenever system loads exceed what a single‑pivot motor can reliably support
• Intended for professional marine installations
• Not intended as a replacement for compact or single‑drive motors
