ABSTRACT:
An outboard motor includes an engine and an exhaust pipe. The engine has a crank case, a cylinder body, and a cylinder head aligned along the front-rear direction of the outboard motor, and arranged to support a crankshaft so as to extend along an up-down direction. The exhaust pipe is arranged to lead an exhaust gas of the engine to a main exhaust passage positioned below the engine. The cylinder head has an exhaust gas outlet opened in the side portion on one side of the cylinder head in the left-right direction of the outboard motor. The exhaust pipe has a bypass exhaust pipe which, in a plan view, extends from the exhaust gas outlet, bypasses the engine along the crank case, and reaches the other side in the left-right direction of the engine.
