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.

The stator, windings, and bearings are all sealed against water ingress.

The \u003cstrong\u003e65111\u003c\/strong\u003e (65mm diameter) offers 2KW peak in a slightly larger package, and the \u003cstrong\u003e65162\u003c\/strong\u003e (65mm, 162mm length) delivers 7.2KW for high-performance eFoil and heavy-rider builds.

The 56115 is rated \u003cstrong\u003eIP68\u003c\/strong\u003e — fully sealed for continuous underwater operation in both fresh and saltwater. The motor relies on natural water flow for passive cooling during operation. Avoid running the motor out of water for extended periods at high power, as the passive cooling depends on water flow.

Peak power is 3600W vs. 4400W. The 6374 is ideal for builds where space is tight or where 3600W is sufficient thrust. 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.

Check for unusual vibration (propeller balance) and verify the ceramic bearings run smoothly before full-power runs.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003chr\u003e\n\u003ch2\u003e❓ FAQ\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eQ1: What is the difference between the \"Motor\" and \"Motor + Propeller\" variants?\u003c\/strong\u003e\u003cbr\u003eThe \"Motor\" variant includes only the 6384 motor with pre-installed phase wires. The \"Motor + Propeller\" variant adds a matched 140×120mm 2-blade propeller designed for the Φ10mm long-thread shaft. 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-a2-1500w-thrust-system-electric-fin","title":"Firduo TUNA Thrust System 1500W 18.5KGF Electric Fin Thruster for SUP \u0026 Kayak","description":"\u003ch3\u003e🌊 All-in-One Electric Propulsion.

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.

The VX3 remote is IP67 rated (submersible to 1m for 30 min). The T2000 motor is fully sealed for continuous underwater operation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ5: Can I use this kit for an ROV, AUV, or non-surfboard application?\u003c\/strong\u003e\u003cbr\u003eYes. The T2000 thruster's wide voltage range and standard 8.0mm bullet connectors make it suitable for ROV, AUV, and USV applications.

KIT-2 includes the complete 65162 Thruster unit (motor + JP120 propeller + C120 guide cover + fixed base + screws) — a ready-to-mount underwater propulsion unit for builders who want a complete drive assembly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: Is a battery included? What battery do I need?\u003c\/strong\u003e\u003cbr\u003eNo battery is included. You need a 12S–16S LiPo or Li-ion pack with a minimum 150A continuous discharge rating. A 14S (51.8V nominal) pack is the most common choice for this kit, balancing power and motor efficiency. Ensure your battery connector is rated for 150A+ and add an anti-spark switch to protect the ESC on connection.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: Is the Manatee 100 ESC waterproof? Do I need to seal it?\u003c\/strong\u003e\u003cbr\u003eThe Manatee 100 is water-cooled but its cable connection points (phase wires, battery leads, signal cables) are not waterproof. You must seal all exposed terminations with self-amalgamating tape or waterproof sealant before water use. Waterproof connectors are recommended for both the live wire and power cord. The \u003cstrong\u003eManatee 100\u003c\/strong\u003e is designed to be waterproof to a depth of 5 meters.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ4: Can I use the VX3 remote with other ESCs, or only the Manatee 100?\u003c\/strong\u003e\u003cbr\u003eThe VX3 is compatible with both VESC-based and non-VESC ESCs via PPM or UART. It works with any ESC that accepts a standard PPM signal. For UART-based telemetry data (motor power, MOS temperature) on the VX3 display, the ESC must support VESC UART protocol — the Manatee 100 is fully compatible.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ5: Do I need to configure the ESC, or is it plug-and-play?\u003c\/strong\u003e\u003cbr\u003eThe Manatee 100 ships with custom firmware 5.03 pre-installed and is pre-configured for general eFoil use. For optimal performance with the 65162 motor, we recommend running the motor auto-detection wizard in VESC Tool 3.01 after assembly.
