Hobbywing Water Cool Tube 2848 For 380 Type Motor

The Hobbywing Water Cool Tube 2848 (Part No: HW30820101) is a high-grade aluminum cooling jacket tailored for 28mm diameter motors, commonly known as 2848 or 380-size brushless inrunners. Specifically designed for the SeaKing series and other high-performance marine motors, this tube provides essential thermal management to prevent power fade and internal damage during prolonged high-speed operation in RC boats.

Key Features:

• Optimized Heat Dissipation: The aluminum sleeve acts as a heat exchanger, transferring thermal energy from the motor can to the circulating water with high efficiency.
• Leak-Proof O-Ring Design: Features two precision-fitted rubber O-rings that create a tight seal against the motor housing, ensuring that cooling water stays within the jacket and out of your hull.
• Dual Water Nipples: Equipped with two 4mm nozzles, allowing for easy connection to standard marine silicone tubing (typically 3x5mm).
• Durable Anodized Finish: Finished in Hobbywing's signature blue anodizing, providing a protective layer against corrosion, which is particularly important for freshwater RC boating.
• Lightweight Construction: Adds minimal mass to the motor assembly, ensuring the boat's center of gravity and overall performance remain unaffected.

Marine Setup Tip:

When installing the 2848 cooling tube, ensure the water inlet (the nipple connected to the pickup) is positioned at the lowest point of the motor if mounted horizontally. This forces water to fill the entire cavity before exiting through the top nipple, eliminating air pockets that can create "hot spots" on the motor can. For maximum reliability, use small zip-ties or "safety wire" on the tubing connections to prevent them from slipping off under high water pressure.
