🌊 Ride Harder. Go Further. Built for Maximum Thrust.

The Firduo 3.7KW Waterproof eFoil Kit is a complete, high-performance propulsion system engineered for lightweight hydrofoil, electric surfboards, kayak and SUP 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

🔗 Compatible Builds & Recommended Pairings

  • eFoil / Hydrofoil boards — direct-drive mast mount; T2000 suited for lightweight hydrofoil applications
  • Electric surfboards (eSurf / Jetboard) — rear or bottom mount; use eSurf cruise mode on VX3
  • SUP / Kayak conversions — fin-box or custom bracket mount
  • Battery: 12S–16S LiPo or Li-ion pack recommended; Battery is not included. The Firduo FD13S5P(5C,20AH,936Wh) fully waterproof battery is also compatible with the T2000 thrusters
  • Recommended Connector: Firduo 120A–250A Waterproof Connector — for sealed battery-to-ESC connection rated for 120A+; Firduo 120A IP68 Waterproof Connector — for sealed ESC-to-motor connection rated for 120A+
  • VESC replacement: Firduo Manatee 100 VESC — if you need an ESC without Bluetooth, requiring higher continuous current and peak current.
  • Signal Connectors: Firduo 3-Core / 4-Core IP68 Waterproof Connector — for receiver, sensor, and hall signal wiring

🛠️ Setup Guide

  1. Check voltage compatibility — confirm your battery is within 4S–20S (14–84V). For T2000 full-power output, 12S–16S with ≥100A burst discharge is recommended.
  2. Mount the T2000 thruster — secure to your board's fin box or custom bracket. Route the 1300mm motor cable away from the propeller; ensure clear water flow around the 360° inlet.
  3. Connect ESC → Thruster — plug the 3× 8.0mm gold bullet connectors into the Manatee 100 Pro phase outputs (A-B-C). Rotation direction can be reversed in VESC Tool — no rewiring required.
  4. Connect ESC → Battery — use a waterproof connector rated ≥100A continuous (e.g. Firduo 120A IP68 connector). Verify voltage is within range before powering on.
  5. Pair VX3 Remote — power on ESC first, then remote. Follow the VX3 pairing procedure in the user manual.
  6. Configure via VESC Tool (recommended) — run motor auto-detection to optimize current limits and throttle curves for the T2000. Our support team can provide a pre-tuned config file on request.
  7. Water test — start at low throttle (0.5 kW / ~13 KGF) in calm water. Check all connections are dry and secure before each session. Gradually increase power as you confirm stable operation.

❓ FAQ

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-TT160 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. The T2000 KIT2/KIT3 offers an aluminum alloy bracket option. For SUP or kayak use, the fin version is recommended as it is compatible with standard fin boxes. For DIY applications, choose the DIY panel interface.Contact us for application-specific wiring diagrams and VESC configuration support.
