How to find the right Boat Windshield Wipers AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Boat Windshield Wipers
- Shaft length versus windshield thickness
- Measure the glass or panel thickness plus any mounting spacers, and choose a motor shaft length that covers it with room for the nut. A shaft that is too short cannot be secured, and one that is too long leaves the arm sitting off the glass.
- Voltage
- Match the motor to the boat's system, 12V or 24V. The wrong voltage either fails to run the motor or burns it out.
- Sweep angle and arm type
- Choose a sweep angle and either a single arm or a pantograph arm so the swept area covers the helmsman's line of sight. A pantograph arm keeps the blade vertical and clears more of a tall rectangular screen.
- Arm and blade length
- The blade should cover most of the screen height without hitting the frame at either end of the sweep. An oversized blade strikes the frame, and an undersized one leaves the view uncleared.
- Marine sealing
- Use a sealed marine motor with stainless or coated arms and a gasket at the shaft. Water entering through the shaft hole corrodes the motor and leaks into the helm area.
Brands that matter
- Marinco: Owns the AFI wiper motors and arms, widely used on US boats.
- Roca: Marine wiper systems for commercial and recreational vessels.
- Exalto: Heavy-duty marine wipers, common on larger and commercial boats.
- Doga: European wiper motors used on many workboats and yachts.
What to avoid
- Automotive wiper motors that are not sealed for marine use
- Buying a motor before measuring windshield thickness
- Using a dry blade on salt-crusted acrylic, which scratches it
Questions
Can I use a wiper on a curved or acrylic windshield?
Flat glass works best. On acrylic, use soft blades and a washer or rinse, because a dry blade on salt will scratch the surface.
