Abstract: A marine propulsion device controller includes a main operator that starts engines of all propulsion devices collectively with a simple operation and increases the degree of freedom of layout on a panel on which the main operator is disposed. The main operator is provided in common for all of the propulsion devices. The main operator receives a first operation and a second operation consecutively after receiving the first operation. All remote control ECUs are activated in response to receiving the first operation. The main operator outputs a collective start command to simultaneously start all the engines of the propulsion devices in response to receiving the second operation. Each remote control ECU starts the corresponding engine based on the collective start command.
