| 1. An outboard motor control apparatus for controlling a hybrid type outboard motor including a propeller, an electric motor
that generates a drive force to rotate the propeller, and an engine that generates a drive force to rotate the propeller,
the engine discharging exhaust gas in water, the outboard motor control apparatus comprising:
a speed instruction unit arranged to generate a speed instruction value indicative of a rotational speed of the propeller;
and
a control unit arranged to change from a first mode, in which only the drive force of the electric motor is transmitted to
the propeller, to the second mode, in which the drive force of the engine is transmitted to the propeller, depending on a
rotation direction of the propeller and the speed instruction value generated by the speed instruction unit; wherein
the control unit is arranged to change from the first mode to the second mode by applying different threshold values to the
speed instruction value generated by the speed instruction unit depending on the rotation direction of the propeller.
