【TRUE BIDIRECTIONAL FORWARD & REVERSE】** Switch between "Forward Only" and "Forward + Reverse" modes via transmitter or LCD program card. Linear throttle response in both directions makes the Shark G2 ideal for twin-screw boats, catamarans, deep-V hulls and underwater thrusters that need precise reverse maneuvering — not a half-power emergency reverse like cheaper ESCs.
【32-BIT MCU + SR SYNCHRONOUS RECTIFICATION】** A new-gen 32-bit microprocessor with optimized BLDC algorithm delivers smoother startup, higher RPM ceiling and rock-steady throttle linearity. Synchronous Rectification cuts MOSFET conduction loss, lowers ESC running temperature and extends battery runtime — proven energy-saving on 6S high-load runs.
【WATERPROOF + INTEGRATED WATER-COOLING PLATE】** Internal PCB is fully potted with marine-grade glue against splashes, mist and humidity inside the hull. The flat aluminum water-cooling plate channels water across both the FET and capacitor zones, holding the ESC well within safe temps even on extended high-throttle runs. **Compatible with standard 3/32" ID × 5/32" OD silicone or PVC tubing — easy to source locally.**
【ADJUSTABLE SBEC, DRIVES STRONG SERVOS】** Built-in switching SBEC is selectable 5V or 6V — **4A continuous on 20A/30A/40A/50A models, 8A continuous on 60A/80A/100A/120A models** — enough headroom to power high-torque rudder servos, FPV cameras, lights or a water pump without a separate UBEC. Wide input 2-4S LiPo (20A–50A) / 2-6S LiPo (60A–120A).
【5 PROTECTIONS + 2 PROGRAMMING WAYS】** Start-up, over-heat, low-voltage cutoff, phase-loss and signal-loss protections guard your motor and pack. Program every parameter (timing / brake / battery cells / cutoff / direction / SR / acceleration) via stick on the transmitter, ZTW LCD Program Card G2.
