In an outboard motor including a vertical electric motor, a cooling structure for the vertical electric motor comprises a cooling oil supply member positioned above the stator and including a plurality of outlets for dropping cooling oil on an upper surface of the stator, the outlets being arranged circumferentially in a coaxial relationship to the stator, and the outlets are configured such that an amount of cooling oil that is dropped on a part of the stator located on a first axis on a plane orthogonal to the vertical axis is smaller than an amount of cooling oil that is dropped on a part of the stator located on a second axis which is orthogonal to the first axis on the plane orthogonal to the vertical axis.
