Hydra Cobra 6 8S Brushless Marine ESC - CSE010-0189-00

Keep your high performance marine rig running cool and fast with the ultimate 8S brushless speed control.

The Hydra Cobra 6 8S Brushless Marine ESC brings legendary Castle power and reliability to the water. Engineered specifically for demanding RC boating applications, this speed control combines intelligent design with the thermal management needed to handle up to 8S LiPo power without breaking a sweat.

Whether you are building a custom monohull, upgrading a catamaran, or competing in high speed oval racing, the Hydra Cobra delivers smooth throttle response, robust data logging, and the fine-tuning options that experienced boaters demand.

Why You'll Love It

• Water Cooled Thermal Management: An integrated anodized aluminum water jacket keeps operating temperatures low, ensuring maximum power delivery during sustained high speed runs.
• Advanced Data Logging: Record critical run data such as battery voltage, motor RPM, ESC temperature, and ripple voltage to optimize your setup.
• Heavy Duty BEC: The adjustable internal BEC provides the power needed for high torque steering servos in demanding marine environments.
• Castle Link Programmability: Fine-tune your throttle curves, braking, cut-offs, and more using the intuitive Castle Link software.

What's Under the Hood

• Input Voltage Range: 2S to 8S LiPo (Max 33.6V)
• BEC Output: Adjustable voltage to match your choice of steering servo
• Telemetry Support: Compatible with Futaba S.BUS2, Spektrum SRXL2, and standard Castle telemetry links
• Water Cooling Fittings: Dual aluminum water ports designed for standard marine silicone tubing

Specifications

• Application: Brushless Marine (Boats)
• Max Cell Count: 8S LiPo
• Programming: Castle Link USB (sold separately) or Field Link card

Needed To Complete

• Brushless Marine Motor: Compatible sensorless or sensored brushless motor
• Battery Connectors: High current connectors (such as Castle 6.5mm Bullets, XT90, or EC5) suited for your battery wires
• Water Cooling Lines: Standard marine silicone tubing for water routing

Note: Always ensure your water cooling system is completely free of debris and flowing water before each run. Pro-Tip: Use the Castle Link software to check your ripple voltage after the first run. If your ripple voltage is high, consider upgrading your battery connectors or shortening the battery to ESC wires to protect your electronics from premature failure.
