Abstract

A control device for plural propulsion units executes a control for synchronization of the engine rotational speed of a target propulsion unit with the engine rotational speed of a reference propulsion unit when one or more specified conditions are satisfied. Once synchronization control has been established, it is only cancelled if one of the specified conditions becomes no longer satisfied for a first prescribed duration or if another of the specified conditions becomes no longer satisfied for a second prescribed duration.
