Abstract
An outboard motor includes a lower casing provided below an upper casing, amounting plate provided above the upper casing, and an engine with a vertically-arranged crankshaft mounted on the mounting plate. The rotation of the crankshaft is transmitted to a drive shaft that is pivotally supported in the upper casing, changed in speed by a transmission mounted on the drive shaft, and transmitted to a propeller shaft that is pivotally supported in the lower casing. The outboard motor has upper mounts and lower mounts arranged to mount the outboard motor on a hull. The upper mounts are disposed on upper lateral surfaces of the upper casing, and the lower mounts are disposed on lower lateral surfaces of the upper casing. The outboard motor simplifies the upper casing for disposing a transmission therein and assembly and maintenance thereof.
