It features a robust rotary interface, variable voltage compatibility, and a water-resistant design engineered for the marine world. Ideal for commercial vessels, yachts, and mid-size to large boats, this switch offers unmatched convenience, control, and reliability.
Overview / What Is Double IMW Wiper Switch
The Double IMW Wiper Switch with Wash, 12-24V is a marine-grade rotary switch that enables control of two independent wiper motors from a single panel-mounted device. It includes an integrated wash function, allowing for simultaneous rinsing and wiping with a single twist-and-push motion. This switch supports both 12V and 24V systems, which makes it widely compatible with a range of vessels.
Designed for helm stations that need maximum control with minimal dashboard clutter, the switch offers multiple speed settings, parking functionality, and a streamlined design to match professional-grade marine equipment.
Key Features of Double IMW Wiper Switch with Wash
- Dual-Wiper Control: Operate two separate wipers independently or in sync.

- Marine-Grade Sealing: IP-rated for saltwater resistance and corrosion protection.
- Rotary Precision: Smooth tactile control, even when wet or gloved.
- Voltage Versatility: Works with 12V and 24V systems.
For larger boats with dual windshields, this switch eliminates the need for multiple buttons or toggles, reducing dashboard clutter and simplifying operation—especially under stress or poor visibility.
How to Install Double IMW Wiper Switch with Wash
Installation is relatively straightforward and can be completed in under an hour with the right tools. Here’s a quick guide:
- Disconnect power at the battery panel to ensure safety.
- Use a 22mm drill hole or reuse an existing panel cutout.
- Mount the switch using included hardware and verify tight sealing against the dash.
- Connect wiring to each wiper motor (L and R), washer pump, power, and ground.
- Test the rotary functions and wash operation before sealing the connections.
Always use marine-grade wire connectors and protective sleeves. Consult your boat’s wiring diagram if replacing older components.
How the Double IMW Wiper Switch Enhances Marine Safety
Dual wiper control becomes critical on vessels with large windshields or split-glass cabins. Instead of toggling separate switches, the Double IMW Wiper Switch with Wash, 12-24V allows you to activate both systems simultaneously for maximum forward visibility. This reduces response time and improves navigational safety.
The integrated washer function ensures that salt spray, mud, or rain streaks can be cleared instantly with a single motion—reducing operator distraction and minimizing the chance of oversight during emergencies or busy docking procedures.
Wiring Compatibility for Marine Engines and Helms
This switch is built to fit the majority of helm dashboards and integrates well with IMW marine systems, and most standard marine wiper motors. Its support for 12-24V makes it flexible for older and newer boats alike.
Here are compatible wiring types:
- Standard dual-speed marine wiper motors
- Washer pump circuits (momentary trigger)
- Direct battery or switch panel wiring (fused)
To enhance performance, pair this switch with wiper arms and blades recommended by Yamaha Outboards for extended service life and superior sweep efficiency.
Maintenance Tips
To maintain optimal performance of your Double IMW Wiper Switch with Wash, 12-24V, follow these proactive maintenance tips:
- Monthly Checks: Inspect wiring terminals for salt corrosion and rust.
- Clean the Switch Knob: Wipe the outer rotary surface with a damp cloth to prevent salt buildup.
- Use Contact Cleaner: Apply electrical contact cleaner to the terminals every 3–6 months.
- Test Functionality: Run the system bi-weekly, even in dry season, to prevent motor freeze or electrical shorts.
Proper maintenance not only extends the switch’s lifespan but also ensures reliability during harsh marine conditions.

Detailed FAQ Section
Can I install the Double IMW Wiper Switch with Wash myself?
Yes, most boat owners with basic electrical knowledge can install the Double IMW Wiper Switch with Wash themselves. You’ll need standard tools like a wire stripper, screwdriver, and crimper. Ensure power is disconnected before starting. The switch fits a 22mm panel hole, and wiring diagrams are provided. Be sure to test all connections, including washer functionality, before completing the installation. If your wiper system includes specialized motors or relay banks, it may be wise to consult a marine electrician.
Is this switch compatible with older marine wiper systems?
In most cases, yes. The Double IMW Wiper Switch with Wash is compatible with both 12V and 24V systems, making it suitable for older boats still running legacy power systems. Compatibility primarily depends on motor amperage and washer wiring. If the existing motors are single-speed or dual-speed and have standard terminal layouts, the switch will integrate without issue. Always double-check specifications and wiring compatibility before installation to avoid overload or performance loss.
What are the advantages over separate toggle switches?
Using the Double IMW Wiper Switch with Wash over separate toggle switches offers several advantages:
- Unified Control: Operate two wipers and a wash function from one interface.
- Dashboard Efficiency: Saves space and declutters your helm area.
- Better Safety: Faster response in emergencies due to streamlined access.
- Waterproof Design: Unlike some toggles, this rotary switch is IP-rated.
These advantages are especially crucial in commercial marine or harsh environmental conditions where reliability and quick operation are key.
How do I know when to replace the switch?
Signs include sluggish or intermittent performance, lack of wash activation, or stiff rotary movement. If the switch knob becomes loose or doesn’t register speeds accurately, internal wear may have compromised the mechanism. Additionally, visible corrosion, melted wires, or a burnt smell near the dash are indicators of critical failure. To avoid navigation risks, it’s best to replace the switch immediately once these symptoms appear.
Can the switch be used in high-salt environments?
Absolutely. The switch is designed specifically for marine applications where exposure to salt, UV, and moisture is routine. It features sealed electrical internals, corrosion-resistant terminals, and a water-resistant outer shell. Regular cleaning and occasional application of contact protector sprays will further enhance its performance in salt-heavy regions such as coastal harbors or offshore fishing zones. It is a long-lasting solution trusted by captains operating under extreme marine conditions.
Conclusion
The Double IMW Wiper Switch with Wash, 12-24V for Boats & Marine Engines is a superior control option for any vessel requiring dual windshield wiping. With its integrated washer function, voltage versatility, and marine-hardened design, it delivers unmatched reliability. Whether you’re cruising the coastline or operating in commercial waters, this switch offers peace of mind through performance and simplicity.
