DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

[0025] Specifically, the fixing plate 1 4 is placed close to one side of the ship, and the bolts on the fixing plate 2 5 are rotated to make the pressure plate on the bolts contact the inner wall of one side of the ship, so that the fixing block 3 fixes the outboard motor on the ship, and then the box cover on the casing 1 is opened to inject fuel into the supporting shell 2, and the fuel is transported to the internal combustion engine 12 through the oil pump 13 and the oil pipe 14 for combustion to generate power.
