An engine unit of an outboard motor comprises an engine body, a crank case in which a crankshaft is vertically perpendicularly arranged in a usable mounted state of the outboard motor, a cylinder block which is disposed to a rear side of the crank case and in which cylinders are arranged, a cylinder head disposed to a rear side of the cylinder block, a magnet device mounted to a top end portion of the crankshaft projecting upward and comprising a stator and a flywheel to which a rotor is integrally formed. In the engine unit, the crankshaft is supported by a bearing boss disposed to a mating portion of the cylinder block and the crank case through a bearing means and an oil seal is disposed between the bearing boss and the bearing means, and the magnet device is mounted to the engine body through the stator through a mounting portion. A diameter of the mounting portion of the stator is to be larger than an outer diameter of the oil seal. |
