Propelling system of powered ship

Abstract

A propelling system of a powered ship includes a support, outboard motor, guide component and water inlet unit. The support is disposed at a stern. The outboard motor is mounted on the support. A blade wheel is disposed at the bottom of the outboard motor. The axis of the blade wheel is higher than a hull. The guide component has a guide ring for concealing the blade wheel and a nozzle connected to the guide ring. The water inlet unit is disposed at the stern and below the support. The water inlet unit has a water inlet hole and water outlet hole. A water inlet channel is formed between the water inlet hole and water outlet hole. The support enables the outboard motor to be mounted higher. The guide component and water inlet channel enable water to be conveyed at low pressure and ejected at high flow rate.

What is claimed is: 
     
         1 . A propelling system of a powered ship, the powered ship having a stern and a hull, the propelling system comprising:
 a support disposed at the stern;   an outboard motor disposed at the support and having a blade wheel, wherein an axis of the blade wheel is higher than the hull;   a guide component having a guide ring and a nozzle, the guide ring concealing the blade wheel, the nozzle being connected to a back of the guide ring and disposed proximate to the blade wheel; and   a water inlet unit disposed at the stern and below the support, having a water inlet hole formed from below, and having a water outlet hole opening toward the guide ring, wherein a water inlet channel is formed between the water inlet hole and the water outlet hole.   
     
     
         2 . The propelling system of a powered ship according to  claim 1 , wherein the water inlet hole is as high as the hull. 
     
     
         3 . The propelling system of a powered ship according to  claim 1 , wherein the outboard motor further has a gear box connected to the blade wheel and partially concealed by the guide ring. 
     
     
         4 . The propelling system of a powered ship according to  claim 1 , wherein the guide ring is disposed at an eddy-preventing baffle of the outboard motor.
