Hobiba eJet95-10.0 Integrated Waterjet Propulsion System High-Thrust, Linear Design Electric Waterjet for Personal Watercraft

eJet95-10.0 Integrated High-Thrust Linear Electric Waterjet (for PWC)

The Hobiba eJet95-10.0 is a compact, high-performance integrated waterjet propulsion system, engineered for the next generation of personal watercraft and light marine vehicles. Utilizing an innovative linear design, it seamlessly merges a high-efficiency permanent magnet brushless motor with a precision jet pump into a single, robust IP68-rated unit. Delivering up to 81 kgf of thrust and speeds capable of exceeding 50 km/h, it provides exhilarating acceleration and top-end performance for applications like electric jetboards and karting boats. Its fully-submerged motor design ensures efficient cooling and quiet operation, while the all-aluminum 6061-T6 construction guarantees durability in saltwater environments. The eJet-10.0 represents a turnkey, high-power density solution that simplifies integration and unleashes powerful, electric propulsion on the water.
