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.

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. Brief out-of-water testing at low power is acceptable for connection verification. After saltwater use, rinse with fresh water to remove salt residue.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ5: What propeller should I use, and what does the Motor + Propeller variant include?\u003c\/strong\u003e\u003cbr\u003eThe \u003cem\u003eMotor + Propeller\u003c\/em\u003e variant includes a matched propeller optimized for the 56115's thrust curve at 48V. The propeller hub is designed for the Φ10mm threaded shaft. If you select the \u003cem\u003eMotor only\u003c\/em\u003e variant, ensure your propeller hub matches the Φ10mm shaft diameter and thread specification.

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.

IP58 certifies the motor for continuous submersion beyond 1 meter depth — suitable for eFoil, underwater thrusters, and ROV applications. The ceramic bearings are specifically selected for corrosion resistance in both fresh and salt water. Always rinse with fresh water after salt water use to maximize bearing and seal longevity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ4: What battery voltage gives the best performance?\u003c\/strong\u003e\u003cbr\u003eFor eFoil and thruster builds, \u003cstrong\u003e12S–14S (44–52V)\u003c\/strong\u003e is the optimal range, placing the motor in its peak efficiency band (refer to the characteristic curves at 36V and 48V above). At 16S (67.2V) you reach maximum power output but generate more heat under sustained load. For lighter builds or SUP thrusters, 10S–12S is a good balance of power and runtime.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ5: Do I need the propeller bundle, or can I use my own?\u003c\/strong\u003e\u003cbr\u003eThe \"Motor\" variant ships without a propeller — you can mount any propeller with a compatible Φ10mm bore.

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":"tuna-underwater-thruster-1500w-18-5kgf-electric-fin-for-sup-surfboards-kayaks-rov-auv-usv","title":"Firduo TUNA 1500W 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. Both deliver identical thrust performance.
