The present invention is directed to a multiple propeller nozzle Venturi system and assembly consisting of two or more hydrodynamically shaped nozzle rings, axially located around the propeller and connected by the means of a plurality of equally spaced ring connecting fin struts to be used on a wide variety of sizes of watercrafts. By adjusting the conical inclination of one or more of the hydronamically shaped nozzle rings the water passing over is directed into the area of the propeller increasing the thrust pressure, thereby creating a Venturi effect. A skeg shield and a skid plate are incorporated to strengthen, or repair if broken, the lower portion of outboard and inboard-outboard motors. The overall effect of the multiple nozzle Venturi system is to enhance the performance, handling and control of a watercraft so equipped. Multiple nozzle Venturi systems are constructed to be adaptable to all sizes of vessels and all motors found on watercraft.
