Abstract
The control apparatus controls an outboard motor having a propeller and an engine that rotates the propeller and discharges exhaust gas in water. The control apparatus includes a judgment unit arranged to determine a reduction in the 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, the output of the engine is increased as compared to when the judgment unit determines that a reduction in the propulsive force does not occur.
