이상과 같이 본 발명은 디젤 주기관으로 종래의 엔진에서 곧바로 기계식 연결방법 형태와 엔진, 유압펌프, 유압모터, 스크류의 순서로 조합된 방식과 달리 유압펌프 및 유압모터를 이용하되 유압모터의 최대출력을 얻을 수 있는 형태 및 유압모터에서 곧바로 스크류로 동력을 전달하는 방식이 아닌 중간에 감속비가 있는 기어를 이용하는 것으로 하였고, 엔진효율 상승효과와 주기관의 경량화를 통해서 속도증가, 화물적재공간 개선이 용이하고 개솔린 엔진에 비해 연료비를 2배이상 절감하였으며 연료소비량 또한 유압시스템에 의해 개선되며, 역전기어와 클러치가 제거되는 대신에 유압시스템으로 대체함으로서 선미추진장치 이하 부속설비일체의 내구성을 향상시켰으며, 조향각과 인양각을 임의 조절 가능하도록 하였고, 종래의 선외기 형태인 폐쇄일체형 구동시스템을 정비유지가 용이한 유압시스템으로 대체하여 정비유지관리비의 절감이 가능하다.As described above, the present invention uses a hydraulic pump and a hydraulic motor as opposed to a combination of a mechanical connection method form and an engine, a hydraulic pump, a hydraulic motor, and a screw in the form of a mechanical engine in a conventional engine. It is to use the gear with the reduction ratio in the middle, not the form that can get power and direct the power from the hydraulic motor to the screw, and it is easy to increase the speed and improve the cargo loading space by increasing the engine efficiency and reducing the weight of the main engine. In addition, the fuel cost is more than doubled compared to gasoline engines, and the fuel consumption is also improved by the hydraulic system.Instead of removing the reverse gear and clutch, the hydraulic system is replaced by the hydraulic system. Steering angle and lifting angle can be adjusted arbitrarily, and the conventional outboard type closed It is possible to reduce maintenance costs by replacing the integral drive system with a hydraulic system that is easy to maintain and maintain.
