An outboard motor includes a lower portion including a propeller shaft, an upper portion including a drive source to provide a rotational force to rotate the propeller shaft, a support portion to rotatably support the lower portion relative to the upper portion about a steering shaft and rotate integrally with the lower portion, a water pump assembly in the upper portion to supply water to the drive source, and a water inlet including a first filter in the lower portion to take in external water. A water channel extends from the water inlet to the water pump assembly, and a seal is between a fixed portion fixed with respect to the upper portion and the support portion. A second filter, which has a mesh size smaller than a mesh size of the first filter, is in the water channel upstream of the seal and downstream of the water inlet.
