a judgment unit arranged to determine a reduction in a propulsive force of the outboard motor due to in-water exhaust of the engine; and
a control unit arranged to control the engine such that, when the judgment unit determines that a reduction in the propulsive force occurs, an output thereof is increased as compared to when the judgment unit determines that a reduction in the propulsive force does not occur.
