MARINE APPLICATION GUIDE
Castle’s legacy of overpowering the surface doesn’t stop at land — it goes full throttle into water. Our Marine Product lineup is purpose-built for high-performance RC boats that demand brutal torque, thermal control, and bulletproof reliability. From the proven Hydra X 8S to the next-generation Hydra Cobra 5 HV 12S, these ESCs are highly capable and designed for high-RPM water-cooled action.
Pair your ESC with our precision-machined 15 Series Water Jacket for maximum heat dissipation and consistent performance during long pulls and hard turns. Whether you're racing, bashing, or building a custom watercraft, Castle’s marine gear is ready to make waves.
High-Voltage Sport and Racing
Push your boat to its limits. The Castle HYDRA COBRA 5 HV is a next-generation marine ESC designed for RC hobby boats up to 50 inches. Built on the same proven technology as the Cobra 5 HV surface ESC and re-engineered for water, it delivers uncompromising 12S / 50.4 V power, data-rich performance monitoring, and bulletproof protection.
Sport and Racing
Based on our proven Cobra 5 architecture, HYDRA COBRA 5 8S is a marine-focused ESC features a custom water-cooled heatsink for efficient thermal management and an aluminum top plate with dual anodized water fittings (.17" OD, 10-32 UNF threads). The ESC is housed in a rugged CNC aluminum case and potted in waterproof epoxy to protect the electronics and includes an upgraded current-sensing and thermal protection system actively mitigates the risk of failure in aggressive or high-load setups.
High-performance Monohulls
The HYDRA X 8S is based on our popular and powerful Mamba Monster X 8S. We've removed the air cooled heatsink and added a water-cooled heatsink. The final touch is an aluminum top plate that gives it a sleek and polished appearance. Attached to the top plate are two .17" aluminum water fittings and uses standard 10-32 UNF threads. The HYDRA X 8S is the ultimate enhancement that propels high-performance monohulls, up to 36 inches in length, to new heights.
