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.

It is compatible with VESC Tool for configuration and real-time monitoring. It uses the STM32F4 MCU and supports the full VESC feature set including FOC, CAN bus, and all sensor types.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: What motors is it compatible with?\u003c\/strong\u003e\u003cbr\u003eIt supports brushless (BLDC), brushed DC, and IPM motors. Sensor support includes sensorless, HALL, ABI encoder, AS5047, and AS5048A. Motor temperature sensors (NTC 10K\/100K, PTC 1K, KTY83\/122) are also supported. In short: if it's a common electric motor type, this ESC can drive it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: Is the waterproofing sufficient for eFoil \/ underwater use?\u003c\/strong\u003e\u003cbr\u003eThe ESC body is sealed to 5 meters depth. The wire exit point is not fully sealed — for underwater installations, wrap the cable exit with self-amalgamating tape or use the optional 120A waterproof connectors (available in the bundle variant) to seal the phase connections. The ESC is designed for eFoil and water sports use.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ4: Can I run two ESCs in a dual-motor setup?\u003c\/strong\u003e\u003cbr\u003eYes. The CAN bus interface allows multiple Manatee 100 Pro units to be daisy-chained for synchronized dual-motor control. This is commonly used in dual-drive electric skateboards and twin-thruster watercraft.

Can I run it in saltwater?\u003c\/strong\u003e\u003cbr\u003eYes. The T2000 motor is fully sealed for continuous underwater operation. The anodized aluminum alloy shell is corrosion-resistant and suitable for both freshwater and saltwater environments. Rinse with fresh water after saltwater use to extend service life. Ensure the motor cable exit point is sealed with waterproof connectors.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ4: How do I reverse the rotation direction if the thruster spins the wrong way?\u003c\/strong\u003e\u003cbr\u003eRotation direction can be reversed in your ESC configuration software (e.g. VESC Tool) by swapping any two of the three phase wire connections in software — no physical rewiring is required. Alternatively, swap any two of the three 8.0mm bullet connectors physically if your ESC does not support software reversal.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ5: Can I use the T2000 for an ROV, AUV, or non-surfboard application?\u003c\/strong\u003e\u003cbr\u003eYes. The T2000's fully waterproof motor, wide voltage range, and standard 8.0mm bullet connector output make it suitable for ROV, AUV, USV, and other high-thrust underwater propulsion applications. The UART\/CAN interface on compatible ESCs (e.g. Manatee 100 Pro) supports autonomous or remotely operated vehicle integration.

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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: What battery do I need, and is it included?\u003c\/strong\u003e\u003cbr\u003eThe kit supports 4S–20S (14–84V). For T2000 full-power eFoil use, a \u003cstrong\u003e12S–16S LiPo or Li-ion pack with minimum 52A continuous discharge (100A burst recommended)\u003c\/strong\u003e is ideal.

What about the connectors?\u003c\/strong\u003e\u003cbr\u003eThe 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.\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.
