MSD series high-speed surface propeller propulsion device is independently developed by Wuhan laurel Green Bay Marine Technology Co., Ltd., which is composed of semi submerged propeller and driving device. Compared with conventional submerged propeller, its surface propeller blade design can reduce the underwater resistance by 30% - 50%. Good acceleration and efficiency. The reduction of 30% - 50% resistance greatly saves fuel and reduces the use cost. At the same time, with the improvement of speed, the performance and maneuverability are also brought into play. It is mainly suitable for yachts, commercial ships and military ships, such as high-speed patrol boats, fishery law enforcement boats, maritime patrol boats, customs anti smuggling boats, high-speed yachts, etc. it is a reliable, efficient and highly mobile fuel propulsion system.
