Buying Guide
What should you consider when choosing a marine windshield wiper motor kit?
- Voltage and power: Most marine kits run on 12V DC. Ensure your boat’s electrical system can safely support the motor power and current draw.
- Shaft size and mounting: Common shafts are 2.5″ (61 mm). Confirm compatibility with your wiper blades and mounting holes.
- Sweep angle: Decide between fixed presets (80° or 110°) and adjustable sweeps (40°–120° or 40°–110°). A wider sweep can clear larger windshields but may require more space for operation.
- Wiring and controls: Some units include four wires (self-park, slow, high, ground). If you’re not comfortable with electrical work, choose a kit with straightforward wiring or professional installation options.
- Material and durability: Marine environments demand corrosion-resistant housings and shafts (often stainless steel). Look for all-weather seals and anti-rotation features.
- Compatibility: For older boats or MRVs, verify part numbers and interchange references (34010, 30991, 4R2.12.R110D, WWF12C18 series) to ensure a seamless replacement.
