Abstract

A controller carries out a method for positioning multiple trimmable marine propulsion devices on a marine vessel transom. The method includes identifying two propulsion devices located one on either side of a transom centerline and defining these as outer propulsion devices. A third propulsion device coupled to the transom between the outer propulsion devices is defined as an inner propulsion device. A user input is received to trim the outer and inner propulsion devices in a single direction with respect to their current trim angles. In response to the user input, the controller outputs a control signal. In response to the control signal, the outer propulsion devices are trimmed in the single direction to a first trim angle and the inner propulsion device is trimmed in the single direction to a second, different trim angle. The controller may rate limit trimming of the outer propulsion devices to accomplish this.
