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.

You must power your receiver or remote receiver separately using a standalone 5V BEC connected to your battery, or a small receiver battery pack. Connect the BEC output to the receiver's power input, and connect the ESC signal wire (JR male) to the receiver's throttle channel. Do not attempt to draw receiver power from the ESC signal wire.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: Is water cooling mandatory, or can I run it air-cooled?\u003c\/strong\u003e\u003cbr\u003eWater cooling is \u003cstrong\u003estrongly recommended and is the primary thermal management method\u003c\/strong\u003e for this ESC. At 200A continuous, the ESC generates significant heat that cannot be dissipated by air alone. Running without water cooling at high current loads will trigger over-heat protection and may permanently damage the ESC. Always ensure water flow through the 4.6mm cooling pipe before powering on for high-current operation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ4: Does this ESC work with sensorless brushless motors?\u003c\/strong\u003e\u003cbr\u003eYes.

The \u003cstrong\u003eManatee 100 ESC uses active water cooling\u003c\/strong\u003e — connect the ESC cooling inlet and outlet to your board's water circuit before high-current operation. Brief low-power testing without water cooling is acceptable, but always ensure cooling is active before full-power riding.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ5: What propeller should I use with the 65111 motor?\u003c\/strong\u003e\u003cbr\u003eThe 65111 has a \u003cstrong\u003e10mm shaft\u003c\/strong\u003e. Propeller selection depends on your target speed, board weight, and battery voltage.

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.

Both share the same Φ10mm shaft, 140KV rating, and IP58 waterproofing, so propellers and mounts are interchangeable.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: Which ESC and remote are recommended?\u003c\/strong\u003e\u003cbr\u003eThe \u003cstrong\u003eFirduo Manatee 100 Pro\u003c\/strong\u003e (75V 100A VESC) is the ideal ESC pairing — it supports FOC mode, covers the full 6S–16S voltage range, and handles the 6374's 75A max current with headroom.

If you already have a compatible propeller or are using a custom prop, choose the Motor-only variant.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: What ESC is recommended for this motor?\u003c\/strong\u003e\u003cbr\u003eThe Firduo Manatee 100 Pro (75V 100A VESC-based ESC) is the recommended pairing. It supports FOC mode, handles up to 100A continuous (150A peak), and covers the full 6S–16S voltage range of this motor. For higher-power builds at 16S, ensure your ESC is rated for the voltage.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: Is IP58 sufficient for eFoil \/ continuous underwater use?\u003c\/strong\u003e\u003cbr\u003eYes. IP58 means the motor is rated for continuous submersion beyond 1 meter depth — suitable for eFoil, underwater thrusters, and ROV applications. The ceramic bearings are specifically chosen for corrosion resistance in both fresh and salt water. Rinse with fresh water after salt water use to extend bearing life.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ4: What battery voltage gives the best performance?\u003c\/strong\u003e\u003cbr\u003eFor most eFoil and thruster builds, \u003cstrong\u003e12S–14S (44–52V)\u003c\/strong\u003e is the optimal range — this puts the motor in its peak efficiency band (see characteristic curves above). At 16S (60V) you get maximum power but higher heat; at 6S–8S the motor is underpowered for eFoil use. The characteristic curves at 36V and 48V are shown in the spec section above.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ5: Can I use this motor for a dual-thruster setup?\u003c\/strong\u003e\u003cbr\u003eYes. Two 6384 motors can be run from separate ESCs connected via CAN bus (if using VESC-based ESCs) for synchronized dual-motor control. Each motor draws up to 88A peak, so ensure your battery and wiring are rated for the combined current. A dual setup is common in twin-thruster kayak and USV builds.\u003c\/p\u003e\n\u003ch3 style=\"margin-top: 20px;\"\u003e🏄 Application Scenarios\u003c\/h3\u003e\n\u003cdiv style=\"text-align: center; margin: 16px 0;\"\u003e\u003cimg style=\"max-width: 100%;\" alt=\"Firduo 6384 motor application scenarios efoil surfboard thruster\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0227\/7805\/2685\/files\/430a96078c80bcde95dde4af4378318c.jpg?v=1761804452\"\u003e\u003c\/div\u003e","brand":"FIRDUO","offers":[{"title":"Motor","offer_id":46663421067442,"sku":"6384-1","price":129.0,"currency_code":"USD","in_stock":true},{"title":"Motor + Propeller","offer_id":46663421100210,"sku":"6384-2","price":159.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0227\/7805\/2685\/files\/4_3d69fcb9-4069-405d-871f-fe4b42f90ce4.jpg?v=1761787842"},{"product_id":"firduo-tuna-tt160-a1-1500w-underwater-thruster","title":"Firduo TUNA 1500W 18.5KGF Underwater Thruster Motor for SUP Kayak Surfboard – CW\/CCW","description":"\u003ch3\u003e🌊 Pure Thrust.

Do I need to do anything special?\u003c\/strong\u003e\u003cbr\u003eYes. 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. Brief out-of-water testing at low power is fine for connection verification.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ5: What's the difference between TT160-A1-1 and TT160-A1-2?\u003c\/strong\u003e\u003cbr\u003eThe two models differ in their \u003cstrong\u003emounting interface\u003c\/strong\u003e. \u003cstrong\u003eTT160-A1-1\u003c\/strong\u003e uses a universal tail fin box interface compatible with standard SUP and surfboard fin boxes — the easiest option for most boards. \u003cstrong\u003eTT160-A1-2\u003c\/strong\u003e uses a DIY custom interface for non-standard mounts, kayak transoms, or custom hull installations.
