eJet95-72V12KW Integrated High-Thrust Linear Electric Waterjet (for PWC & Marine Craft)

eJet95-72V12KW Integrated High-Thrust Linear Electric Waterjet (for PWC & Marine Craft)

The eJet95-12.0 is an advanced, high-power integrated waterjet propulsion system designed for next-generation personal watercraft and light marine applications. Featuring an innovative all-in-one linear architecture, it combines a high-efficiency permanent magnet brushless motor with a precision-engineered jet pump into a single, rugged IP68-rated unit. Capable of delivering up to 87 kgf of thrust and propelling watercraft to speeds exceeding 55 km/h, the eJet108-12.0 offers exhilarating acceleration and top-tier performance for electric jetboards, karting boats, and lightweight jet skis. Its fully-submerged motor design ensures optimal thermal management and exceptionally quiet operation, while the anodized aluminum 6061-T6 construction guarantees long-term durability in demanding saltwater environments. The eJet108-12.0 is a turnkey, high-power-density propulsion solution that simplifies installation and delivers robust, reliable electric drive on the water.
