Product Details

This is a matched pair of high-efficiency underwater thrusters designed for RC boats, ROVs (Remotely Operated Vehicles), and autonomous underwater vehicles (AUVs). The set includes one Clockwise (CW) and one Counter-Clockwise (CCW) unit, allowing for balanced, dual-motor propulsion layouts that eliminate rotational torque steering.

Specifications

  • Motor Type: High-efficiency brushless DC motor.
  • Operating Voltage: 12V – 24V DC.
  • Maximum Current Draw: 20A (Requires a suitable Electronic Speed Controller).
  • KV Rating: 480 KV (RPM per Volt).
  • Propeller: 4-Blade high-pitch propeller (60mm diameter).
  • Dimensions: Overall diameter 260mm / Propeller diameter 60mm.
  • Weight: ~ 162g per unit.
  • Waterproof Rating: Fully sealed up to a depth of 20 meters.
  • Materials: 304 Stainless Steel bearings, Aluminum Alloy motor shell, and durable PLA/PC composite propeller housing.

Key Features

  • Matched CW/CCW Pair: Running a twin-thruster setup with opposing rotations counteracts the paddle effect, ensuring your watercraft tracks completely straight without constant rudder correction.
  • Deep-Water Waterproofing: Double-sealed construction allows reliable operation in fresh or saltwater down to a depth of 20m.
  • High Power-to-Weight Ratio: Utilizing an outrunner brushless architecture, these compact 162g units deliver high thrust output relative to their physical footprint.
  • Durable 4-Blade Design: The 60mm 4-blade propeller is optimized to shift large volumes of water quickly, providing immediate acceleration and high static thrust for heavy hulls or ROV frames.

Wiring & ESC Requirements

  • Phase Wires: Three brushless motor phase leads (typically bare or bullet connectors).
  • ESC Selection: Each thruster requires a dedicated, waterproof Brushless ESC rated for at least 30A to safely handle the 20A continuous maximum draw under load.
  • Direction Tuning: To reverse the physical rotation of either motor, simply swap any two of the three phase wires connecting the motor to its ESC.

Common Applications

  • RC Jet Boats: High-speed surface craft requiring reliable, weed-resistant propulsion.
  • Underwater ROVs & AUVs: Direct-drive thrusters for marine exploration, hull inspection drones, and camera rigs.
  • Kayaks & Paddleboard Assist: Miniature auxiliary power pods for lightweight personal watercraft.

Usage Tips

  • Never Run Dry: Brushless underwater thrusters rely on the surrounding water for cooling and bearing lubrication. Running them out of the water for more than a few seconds can warp the seals and damage the internal bearings.
  • Rinsing Protocol: After operating in saltwater or muddy environments, always submerge and run the thrusters briefly in clean freshwater to clear out salt crust and debris.
  • ESC Placement: While the motors are completely waterproof, standard ESCs are not. Ensure your speed controllers are housed in a dedicated watertight compartment or utilize fully potted marine ESCs.
  • Debris Protection: If operating in areas with heavy weeds or plastics, consider installing a simple mesh intake guard around the thruster shroud to prevent propeller binding.
