Schmitt Marine Heavy Duty 2-Speed Wiper Motor – 2.5" Shaft – 12V

MPN: 30991

Keep your windshield clear in all conditions with the Schmitt Marine Heavy Duty 2-Speed Wiper Motor, built for reliable performance in demanding marine environments. Designed for boats that require strong, consistent wiping action, this motor delivers dependable operation in rain, spray, and heavy weather.

Featuring a heavy-duty 12V motor with two-speed operation, it allows you to adjust wiping speed based on conditions. The 2.5-inch shaft length makes it ideal for thicker windshields and installations where extra reach is required. Built with corrosion-resistant components, this motor is engineered for long service life on powerboats, commercial vessels, and offshore applications.


Key Performance Features

  • Dual Speed Operation: Offers both High and Low speed settings, allowing you to adjust the sweep frequency based on the intensity of the weather.

  • Adjustable Sweep Angle: The motor can be set to different sweep angles (80°, 100°, or 110°) to perfectly match the dimensions of your windshield.

  • Self-Parking Capability: Automatically returns the wiper arm to the "Park" position (either left or right) once the switch is turned off, ensuring the blade doesn't obstruct your view when not in use.

  • 2.5" Shaft Length: The mid-sized shaft length is ideal for mounting through standard-thickness fiberglass or aluminum bulkheads and window frames.

  • Quiet & Efficient: Designed with vibration-dampening components to ensure smooth, quiet operation that won't distract the captain at the helm.

Installation & Wiring Tips

  • Shaft Alignment: When drilling your mounting hole, ensure the motor is perfectly perpendicular to the glass. An angled shaft can cause the wiper blade to "skip" or apply uneven pressure, leading to streaks.

  • Wiring the 2-Speed Switch: This motor requires a specific 3-position wiper switch (Off-Low-High) to function correctly. Ensure you use marine-grade 14 or 16 AWG wire to prevent voltage drop over long runs.

  • Seal the Penetration: Use the included rubber gaskets, but also apply a small dab of marine-grade silicone sealant around the shaft base on the exterior to ensure a 100% watertight seal.

  • Arm Compatibility: This motor features a standard 13.75mm knurled shaft, compatible with most Schmitt Marine and standard pantograph or radial wiper arms.


Ideal For

  • Powerboats and cruisers

  • Commercial and offshore vessels

  • Replacement or upgrade of existing wiper motors

  • Marine windshield installations requiring a longer shaft
