The Firduo 3.7KW Waterproof eFoil Kit is a complete, high-performance propulsion system engineered for electric surfboards, hydrofoils, and eFoil builds that demand more power. Combining the Manatee 100 Pro VESC, T2000 Underwater Thruster (2000W rated / 3700W peak), and VX3 Waterproof Remote, this kit delivers up to 32 KGF of thrust with full waterproof protection across the entire system — so you can focus on the ride, not the wiring.
Compared to the 2KW kit, the T2000 thruster delivers 73% more thrust at rated power, installed directly on the mast for lightweight hydrofoil applications

📹 Video walkthrough:
Q1: How is this 3.7KW kit different from the 2KW kit?
The key difference is the thruster: this kit includes the T2000 (2000W rated / 3700W peak / 32 KGF), while the 2KW kit uses the TUNA thruster (1500W / 18.5 KGF). The T2000 delivers 73% more thrust at rated power — It can provide higher speed. The ESC (Manatee 100 Pro) and remote (VX3) are identical across both kits.
Q2: Do I need to configure the ESC before use?
The kit works out of the box with default VESC settings for most builds. However, we strongly recommend running motor auto-detection via VESC Tool (free, PC/Mac/mobile) to optimize performance for the T2000's higher current range. Our support team can provide a pre-tuned config file on request. Bluetooth connectivity is also supported for wireless configuration.
Q3: What battery do I need, and is it included?
The kit supports 4S–20S (14–84V). For T2000 full-power eFoil use, a 12S–16S LiPo or Li-ion pack with minimum 52A continuous discharge (100A burst recommended) is ideal. Battery is not included. The Firduo FD13S5P (5C, 20AH, 936Wh) fully waterproof battery is compatible — contact us for build-specific recommendations.
Q4: Is the ESC truly waterproof? What about the connectors?
The Manatee 100 Pro ESC body is waterproof to 5 meters depth. The wire end (where cables exit) is not fully sealed — ensure this area is above the waterline or use waterproof silicone sealant / waterproof connectors at the cable exit point. The VX3 remote is IP67 rated (submersible to 1m for 30 min). The T2000 motor is fully sealed for continuous underwater operation.
Q5: Can I use this kit for an ROV, AUV, or non-surfboard application?
Yes. The T2000 thruster's wide voltage range and standard 8.0mm bullet connectors make it suitable for ROV, AUV, and USV applications. The UART/CAN interface on the Manatee 100 Pro supports autonomous or remotely operated vehicle integration. Contact us for application-specific wiring diagrams and VESC configuration support.
