Abstract: A method for positioning two or more trimmable marine propulsion devices coupled to a transom of a marine vessel includes identifying two propulsion devices located one on each of a port side and a starboard side of a centerline of the transom and spaced symmetrically with respect to the centerline. The two propulsion devices are defined as a first set and are associated with a first target trim position. The method also includes defining a second set of propulsion devices and associating the second set with a second target trim position. When in auto-trim mode, each propulsion device in a set of propulsion devices is actuated to its target trim position only if the actual trim positions of all propulsion devices in the set differ from the target trim position by at least a given amount. The propulsion devices may be actuated individually in response to a user sync command.
