摘要： An outboard motor includes an engine, and a propeller driven by the engine via a drive shaft and a propeller shaft, a tilting mechanism that changes a tilt angle of the propeller shaft and/or the drive shaft, a triaxial acceleration sensor and a triaxial angular velocity sensor, and a controller. The controller is configured to acquire at least one of a gravity direction, a traveling direction, or a horizontal direction of the hull using the triaxial acceleration sensor, and detect at least one of a first angle of the drive shaft with respect to the gravity direction, a second angle of the propeller shaft with respect to the traveling direction, or a third angle of the propeller shaft with respect to the horizontal direction using the triaxial angular velocity sensor, to thereby control the tilting mechanism to adjust the tilt angle of the drive shaft and/or the propeller shaft.

摘要： An outboard motor includes an engine, an engine cover with which the engine is covered, an intake pipe disposed between an outer surface of the engine and an inner surface of the engine cover, and a battery. The engine includes a piston that reciprocates rectilinearly and a crankshaft that rotates around a crankshaft axis extending in an up-down direction. The intake pipe is connected to a first outer surface of the engine along the crankshaft axis, and supplies air to the engine. The battery is disposed between a second outer surface of the engine, which is different than the first outer surface, and the inner surface of the engine cover.
