1. An outboard motor attachable to a hull of a marine vessel, the outboard motor comprising: an internal combustion engine including an oil filler to feed oil thereto and an oil filter to filter the oil; and a cowl to cover the internal combustion engine; wherein in a case that a direction perpendicular or substantially perpendicular to a bottom of the hull is a vertical direction, the cowl is separable into a top cowl to cover an upper portion of the internal combustion engine and a side cowl to cover a side portion of the internal combustion engine; at least a portion of the oil filler or at least a portion of the oil filter is located above a separating line which is a boundary between the top cowl and the side cowl; in a case of attaching and detaching the oil filter, a rotation axis of the oil filter is tilted with respect to a crank shaft of the internal combustion engine so that an upper end of the oil filter is located farther outside the internal combustion engine than a lower end of the oil filter; and an upper half of the oil filter is located above the separating line.
