If you’re a water sports enthusiast or a DIY hobbyist looking to upgrade your aquatic gear with high-performance, reliable electric power, the Maytech MTWJ12KW Max 80V Electric Jet Kit is the ultimate solution you’ve been waiting for. Designed for seamless integration with a wide range of watercraft, this all-in-one kit delivers unbeatable power, precision control, and rugged durability—perfect for electric surfboards, electric jet skis, electric kayaks, electric boats, and more. Whether you’re building a custom watercraft from scratch or retrofitting an existing one, this jet kit redefines what electric marine propulsion can do.
Unmatched Performance: Engineered for Power and Efficiency
At the core of the MTWJ12KW Jet Kit is the MTWJ12KW-130 water jet motor, a powerhouse engineered to deliver extreme performance without compromising on efficiency. Boasting a voltage range of 48-80V (20S LiPo) and a maximum power output of 13.2KW at 80V—ensuring blistering acceleration and smooth, consistent power on the water. With 130KV and 94% maximum efficiency, it strikes the perfect balance between raw power and energy savings, letting you spend more time on the water and less time charging.
The motor’s robust construction (12N/10P) and 120°C maximum working temperature make it built to withstand the harshest marine conditions, while its AC500V/10MA/3S insulation voltage and leak current rating ensures safe, reliable operation. The kit also includes impeller (stainless steel or aluminum) (shipped randomly), both precision-machined for optimal water flow and thrust, with a net weight of just 7.3kg for the motor + jet pump assembly—keeping your watercraft lightweight and agile.
Complementing the motor is the MTSF300A-WP32-HVPRO 300A 85V Waterproof ESC (Electric Speed Controller), a game-changer for marine propulsion. With an IP68 waterproof rating, this ESC is fully submersible and impervious to water, dust, and corrosion—ideal for all water-based applications. It delivers a 300A continuous current and 320A peak current (10S), with an input voltage range of 22.2V-85V (6-20S LiPo) and 100,000 max ERPM. Equipped with a 32-bit microprocessor and built-in Bluetooth module for programming, it lets you fine-tune performance parameters via the included Bluetooth USB cable—customizing speed, torque, and response to match your watercraft and riding style. Its 6AWG cable gauge ensures minimal power loss, making it the perfect partner for the MTWJ12KW motor.
Intuitive Control: Waterproof Remote with Smart Features
No high-performance jet kit is complete without precise, user-friendly control—and the MTWJ12KW Kit delivers with the MTSKR1905WF Updated Waterproof Remote Controller (a wired throttle twist option is also available). This state-of-the-art remote is built for the water, featuring two layers of nanometer-coating for enhanced waterproofing and a wireless charging function for hassle-free power. The backlit display screen keeps you informed with real-time data, including remote battery voltage, main battery voltage (3-18S), motor RPM, current, temperature, etc.—so you always have full visibility of your watercraft’s performance.
The remote is packed with smart, rider-centric features:
- 3 adjustable speed modes and Eco/Pro signal strength modes for personalized riding
- Throttle lock function for enhanced safety, preventing accidental acceleration
- Cruise control (Esurf mode) for effortless long-distance riding
- Brake function (Esk8 mode) for precise stopping power
- Main battery voltage percentage display for easy power management
- Compatibility with Maytech’s 32-bit ESCs to read real-time current/voltage/RPM data
- Ability to wirelessly control two switches (e.g., lights, pumps) for added functionality
- Dual-source power supply (5V/3.3V) for the receiver, ensuring reliable connectivity
With enhanced signal strength to avoid interference and a included receiver + charging pad, this remote offers a seamless, lag-free connection—even in challenging marine environments. A free random-color accessory strip adds a touch of customization, making it as stylish as it is functional.
Tested and Proven: Unrivaled Thrust and Reliability
Maytech doesn’t just claim performance—they prove it. The MTWJ12KW Jet Kit has undergone rigorous testing across all voltage ranges, delivering impressive thrust and efficiency in real-world conditions. At 80V full throttle, the kit produces an astonishing 101.7kgf of thrust with an input power of 13200W, while at 72V full throttle, it hits 88.3kgf of thrust—enough to power heavy watercraft like electric jet skis and small electric boats with ease. Even at lower voltages, it excels: 60V full throttle delivers 65.9kgf of thrust, 48V hits 45.6kgf, and 36V produces 26.2kgf—making it versatile for lighter craft like electric surfboards and kayaks.
The kit’s thrust/power ratio is equally impressive, with up to 24.58kgf/kw at 80V 20% throttle—ensuring efficient power usage and longer run times. Tested with and without a water inlet fairing, it maintains consistent performance across all conditions, with a motor efficiency nephogram showing peak efficiency of 94.27%—a testament to its precision engineering.
Versatile Application: Power Every Watercraft You Own
The MTWJ12KW 80V Electric Jet Kit is designed for unlimited versatility, making it the go-to propulsion system for nearly all electric watercraft:
- Electric surfboards/efoils/hydrofoils: Delivers the instant torque and smooth acceleration needed for agile, high-speed riding on the waves.
