🔧 Product Description

The BAYWATT 12V 1100 GPH automatic bilge pump is fully submersible and engineered for continuous use in saltwater or freshwater bilges. It combines a compact footprint with a powerful motor and corrosion-resistant build. The integrated float switch ensures hands-free operation. Ideal for unattended drainage or as part of a multi-pump setup.

⚙️ Operation

Automatic activation at water levels between 40–50 mm, with stop around 20–30 mm. Uses a three-wire system for automatic and manual control:

  • Brown-white: Connect to +12V for float switch automatic mode
  • Brown: Optional manual override via switch
  • Black: Connect to battery ground (-)

Manual control can be added using an ON-OFF-(ON) toggle or compatible bilge panel.

🔌 Wiring Options

🔁 Alternative: Use a momentary (ON)-OFF RGB push-button to trigger manual bypass while keeping auto mode always powered. LED status: green = running, blue = standby, red = manual override.

⛵ Applications & Compatibility

  • Motorboats up to 9 meters (30 feet)
  • Sailboats up to 30 feet
  • Inflatable boats and tenders with deep bilges

Suitable for seawater or freshwater only. Do not use with fuel or oil-based liquids.

⚓ From the Workshop
