Abstract

A marine vessel includes a hull, an operator station having an operator interface configured to receive a mode input and a lever position input, a left propulsion system, a right propulsion system, and a control module. Each of the propulsion systems includes an engine, a transmission, a troll valve configured to adjust clutch slip, a shaft, a shaft speed sensor configured to detect the speed of rotation of the shaft, and a propeller. The control module is configured to receive the mode input and the lever position input from the operator interface, receive signals from the left shaft sensor indicating a left shaft speed, receive signals from the right shaft sensor indicating a right shaft speed, determine if the vessel is operating in a trolling state, and determine if a sync mode is active, based on the mode input. If the sync mode is active and the vessel is in a trolling state, the speed of the left shaft and the right shaft are synchronized.
