<P>PROBLEM TO BE SOLVED: To provide a control device for an actuator of a ship propeller and the ship propeller, capable of accurately determining the replacing timing of the actuator in the ship propeller separately from operation time of an engine. <P>SOLUTION: This control device is an actuator control device 50 for the ship propeller having an advance-retreat switching mechanism for switching an advance gear and a retreat gear by driving a dog clutch by shift operation, and the actuator 100 driving the dog clutch based on the shift operation, and has a means 52 counting a shift frequency of the shift operation, and a storage means 53 storing a shift cumulative frequency of the shift operation, and stores an added-up shift cumulative frequency in the storage means by adding up the counted shift frequency to the stored shift cumulative frequency. <P>COPYRIGHT: (C)2008,JPO&INPIT |
