At 12S–16S (50–67V), this produces strong low-end torque ideal for eFoil liftoff and efficient cruising. The 65162 120KV is the most popular choice for direct-drive eFoil and hydrofoil builds. If you need higher RPM for a different application, contact us and we’ll advise the best configuration.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: Is the motor truly IP68 waterproof? Can I use it in saltwater?\u003c\/strong\u003e\u003cbr\u003eYes. The 65162 is rated IP68 — fully sealed for continuous underwater operation in both freshwater and saltwater. The stator, windings, and bearings are all sealed against water ingress. Rinse with fresh water after saltwater use and inspect the shaft seal periodically to extend service life.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: What ESC do I need, and is the FD75200 the right choice?\u003c\/strong\u003e\u003cbr\u003eThe 65162 requires an ESC capable of handling up to 200A peak current at 40–80V.

You must seal all cable penetrations using waterproof connectors (e.g. AS150, XT150 with O-rings) or marine-grade silicone sealant. Or keep cable exit points above the waterline whenever possible.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: What motor is this ESC designed for?\u003c\/strong\u003e\u003cbr\u003eThe FD75200 is optimized for the \u003ca href=\"https:\/\/firduo.com\/products\/65162-100kv-120kv-motor\" style=\"color: rgb(0, 0, 255);\" target=\"_blank\"\u003eFirduo 65162 120KV Waterproof Motor\u003c\/a\u003e in eFoil and electric surfboard applications. It is also compatible with any BLDC motor that operates within the 14–75V \/ 200A continuous range. Sensored (ABI, HALL, AS5047, AS5048A) and sensorless operation are both supported.

The three-pipe cooling block is built into the ESC. You need to connect a small external water pump (12V, 3–5 L\/min flow rate recommended) and hoses to circulate water through the cooling block. Use silicone hose rated for 60°C+. Ensure the cooling loop is primed and air-free before powering on. Without active cooling, the ESC will overheat and trigger thermal protection at high current.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ4: How do I configure the ESC, and is VESC Tool required?\u003c\/strong\u003e\u003cbr\u003eThe FD75200 is based on the VESC open-source platform and is configured using \u003ca href=\"https:\/\/vesc-project.com\/\" style=\"color: rgb(0, 0, 255);\" target=\"_blank\"\u003eVESC Tool\u003c\/a\u003e (free download for PC\/Mac\/Linux). Connect via USB, run the motor detection wizard, and set your current limits, throttle curve, and protection thresholds. While the ESC ships with default settings that work for most builds, we strongly recommend running motor auto-detection for optimal performance. Our support team can provide a recommended config file for 65162 motor + FD75200 combinations on request.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ5: What battery do I need, and what connector should I use?\u003c\/strong\u003e\u003cbr\u003eThe FD75200 supports 14–75V (3S–16S). For eFoil use, a 12S–16S LiPo or Li-ion pack with \u003cstrong\u003eminimum 200A continuous discharge\u003c\/strong\u003e (300A burst) is required for full-power operation. Use a high-current connector rated for 200A+ — AS150, XT150, or equivalent anti-spark connectors are recommended.

The ESC draws water from your board's water intake (typically a small hull fitting) and circulates it through the ESC cooling channels. Without water cooling, the ESC will overheat at sustained high current. At low power (testing, slow speed), brief operation without cooling is acceptable, but always ensure cooling is active before full-power riding.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ4: What propeller should I use, and is the DIY propeller suitable for eFoil?\u003c\/strong\u003e\u003cbr\u003eThe optional DIY propeller included in the 120KV+DIY Propeller variant is a 7-inch propeller suitable for initial testing and lower-speed applications.

The ESC body can be submerged. However, \u003cstrong\u003ecable connection points\u003c\/strong\u003e (battery, motor, signal cable terminations) are not inherently waterproof — ensure all solder joints and connector terminations are sealed with appropriate waterproofing (heat-shrink with adhesive, potting compound, or waterproof connectors) before submerging.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ4: What motor is recommended for the Walrus ESC?\u003c\/strong\u003e\u003cbr\u003eThe Walrus ESC is optimized for the \u003ca style=\"color: rgb(0, 0, 255);\" href=\"https:\/\/firduo.com\/products\/4310103556173\" target=\"_blank\"\u003eFirduo 65111 150KV IP68 Waterproof Motor\u003c\/a\u003e for SUP and kayak propulsion builds at 10S–14S.

It is designed for water sports use including eFoil, electric surfboard, and kayak applications in both freshwater and saltwater. The internal large-cavity design also allows the remote to float naturally if dropped in water — no float rope required. Rinse with fresh water after saltwater use to extend service life.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: Which ESCs is the VX5 compatible with?\u003c\/strong\u003e\u003cbr\u003eThe VX5 supports VESC, FTESC, FOCBOX, and PPM-based ESCs. It is fully compatible with the Firduo Manatee 100 Pro VESC via UART or PPM connection.

Charge using the included cable; the display shows real-time charging power so you always know the status. A full charge from empty takes approximately 2–3 hours. The built-in high-precision battery meter shows remaining charge accurately on the display.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ4: What's the difference between Surfboard Mode and E-Skateboard Mode?\u003c\/strong\u003e\u003cbr\u003eSurfboard Mode is optimized for water sports — it supports up to 20 power levels for fine-grained speed control, which is critical for eFoil balance and wave riding. E-Skateboard Mode uses L\/M\/H gear switching with configurable throttle percentages, better suited for street riding where quick gear changes are more important than fine power gradation. Both modes support throttle curve presets and auto-lock.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ5: Can I update the firmware, and how?\u003c\/strong\u003e\u003cbr\u003eYes. The VX5 supports OTA (over-the-air) firmware upgrades — no cables or special tools required. Connect to the upgrade portal via the VX5 app or follow the instructions in the manual. Firmware updates add new features, fix bugs, and improve ESC compatibility.

The TUNA A1 uses a \u003cstrong\u003epassive water-cooled tube\u003c\/strong\u003e that draws water through the motor housing as the thruster moves through water — no pump or external cooling loop required. This keeps the motor cool during normal operation. Avoid running the thruster out of water for extended periods, as the passive cooling relies on water flow.

However, we recommend running motor auto-detection via VESC Tool (free, PC\/Mac) to optimize performance for your specific motor and battery combination. Bluetooth connectivity is also supported.Our support team can provide a recommended config file on request.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: CW vs CCW — which variant do I need?\u003c\/strong\u003e\u003cbr\u003eThis depends on your thruster's mounting orientation. When looking at the thruster from behind (water-facing side), CW rotates clockwise and CCW rotates counter-clockwise. when viewed from behind the board (water-facing side), CW rotates clockwise and CCW rotates counter-clockwise. Single drive, with the option to freely choose between CW and CCW.If dual drive is required, please select both CW and CCW.
