12V 300W Brushless Underwater Thruster 2.5kg Thrust Waterproof Motor for ROV Bait Boat Fishing Rescue RC Boat DIY Model Parts

# 12V Brushless Underwater Thruster ##
Product Introduction：
A high-performance brushless thruster designed for underwater robots (ROVs), bait boats, fishing boats, rescue boats, and other watercraft. It features strong power output and easy installation, making it an ideal power solution for DIY water projects.
Core Selling Points
1. **Strong Power Output** Rated at 12V 300W with a peak current of 28A, each thruster delivers approximately 2.5kg of thrust. It provides sufficient power for small to medium-sized boats and underwater equipment, performing reliably in currents and wind conditions.
2. **High-Efficiency Brushless Motor** Adopts a brushless motor design for higher efficiency, lower heat generation, and longer service life compared to brushed motors. Reduces maintenance needs and is suitable for long-term, frequent use.
3. **Standard Mounting Design for Versatile Compatibility** Compact body dimensions of 70×75mm with pre-drilled M4 screw holes (20mm mounting distance). Easy to secure to boat hulls or equipment brackets, perfect for DIY modifications.
4. **Multi-Scenario Application** Compatible with bait boats, fishing boats, rescue boats, underwater ROVs, RC boat models, and various other water/underwater DIY projects.
5. **Lightweight & Flexible Installation** The compact housing and 10cm motor wires minimize space usage, allowing easy integration into different-sized hulls for lightweight modifications.
--- ## Important Notes
1. **ESC Compatibility Requirement** Must be used with a 40-80A brushless ESC. The motor will not rotate if connected directly to a power supply. Always test with a properly matched ESC first.
2. **Waterproofing & Operating Environment** As an underwater thruster, ensure the motor and wiring are properly waterproofed before use to prevent short circuits caused by water ingress.
3. **Power Supply & Load Limitations** Use only a 12V DC power supply. Do not exceed the rated voltage or current to avoid motor burnout. Prevent foreign objects from tangling the propeller, which may cause stalling or overload.
4. **Installation & Commissioning** Secure the thruster firmly during installation to prevent loosening or detachment during operation. Test the direction and speed under no-load conditions before first use.
5. **Safety Precautions** Do not touch the rotating propeller during operation to avoid injury. If the device malfunctions or overheats, disconnect power immediately for inspection.
