Water jet motor for kayaks and rubber boats has been developed. During the development, different types of motor designs have been designed, in which steering is carried out by means of a rope or a rigid shaft. The structure has been designed for the motor capacity in the range of 1.6-3.5 hp. According to the results of engineering development, the type of rope control has been chosen as a pre-production prototype. A special joystick has been developed as a motor control, the handle of which controls both gas and thrust vector. During the manufacture of a pre-production prototype, production support has been provided (manufacturing of molds for plastic and polyurethane parts, machining and assembly).
