This depth of configurability allows you to dial in perfect behaviour characteristics for your specific boat platform and racing conditions.
• Sleek Compact Design for Easy Installation — The elongated, narrower form factor measuring just 91x41x25.5mm is 7mm slimmer than predecessor models, fitting easily into confined spaces within boat hulls and engine compartments. This streamlined profile enhances installation convenience and offers greater adaptability for both professional racing applications and recreational builds.

Technical Performance

The Hobbywing SeaKing 160A V4 represents a significant engineering achievement in brushless RC boat electronics. As a sensorless brushless speed controller, it operates without shaft sensors, relying instead on advanced back-EMF detection to commutate the brushless motor with precision and responsiveness. The 160-amp continuous current rating with 800-amp peak capability provides the thermal and electrical capacity for large displacement brushless motors whilst maintaining reliability during sustained high-performance operation. The dual-channel water cooling system directly addresses one of the primary failure modes in RC boat electronics—thermal stress—by actively dissipating generated heat through contact with your cooling fluid, a feature found only in premium-tier controllers. Input voltage flexibility spanning 3-8S LiPo chemistry ensures compatibility with virtually any modern battery configuration, from modest 3S setups delivering around 11.1 volts through to aggressive 8S systems providing 29.6 volts. The integrated BEC generates clean, regulated 6V, 7.4V, or 8.4V output selectable via software, capable of supplying 8 amps continuously or 25 amps instantaneously to power servos and receiver systems. All connections utilise marine-grade connectors and heavy-gauge wiring—10AWG red and black input leads measuring 160mm for battery connection, and three 12AWG black output wires of 150mm length terminated with 6.5mm gold female plugs for motor connection—ensuring excellent conductivity and minimal voltage drop even during maximum current draw. The entire assembly weighs just 220 grams including connectors and output plugs, maintaining a weight-conscious design critical for boat performance. The switch-mode BEC topology provides stable voltage regulation across varying input battery conditions and load scenarios. Advanced firmware enables freewheeling function, AUX channel control for real-time parameter adjustment, capacitor overheating protection, and optimised throttle linearity for precise, responsive control even during high-load applications. The brushless design inherently offers superior reliability, longer operational life, lower maintenance requirements, and better efficiency compared to brushed alternatives, making it the standard choice for serious RC boat racing throughout the UK and internationally.
