The invention provides an outboard outboard engine structure capable of changing the underwater depth of propellers, and belongs to the technical field of outboard outboard engines. Comprising a propeller shell and an outboard enclosure, the outboard enclosure is installed on the top of the propeller shell, the propeller shell is located on the underwater part, the outboard enclosure is located on the overwater part, and a positioning shell is fixedly installed on the top of the propeller shell. By arranging the telescopic assembly, a user pulls or pushes a propeller shell to drive a positioning shell to slide in a displacement shell, meanwhile, the positioning shell drives an inner cylinder to slide in a transfer cylinder, and a gear is meshed with a second rack and a first rack on the same side, so that the positioning shell and an outboard outer shell move towards the displacement shell; and the movement directions are opposite, so that the distance difference among the displacement shell, the propeller shell and the positioning shell is changed, and the problem that an existing outboard outboard engine cannot be matched with different ship launching depths is solved.

    本发明提供一种能够改变螺旋桨下水深度的舷外挂机结构,属于舷外挂机技术领域。包括推进器外壳与舷外挂机壳,所述舷外挂机壳安装在推进器外壳顶部,所述推进器外壳位于水下部分,且舷外挂机壳位于水上部分,所述推进器外壳顶部固定安装有定位壳。本发明通过设置伸缩组件,使用人员通过拉动或推动推进器外壳,使其带动定位壳在位移壳内滑动,同时,定位壳带动内筒在中转筒内滑动,且齿轮与同侧的双齿条二以及齿条一发生啮合,使得定位壳与舷外挂机壳均向位移壳运动,且运动方向相反,从而改变位移壳、推进器外壳与定位壳之间的间距差,以解决现有的舷外挂机不能匹配不同船只下水深度的问题。
