ABSTRACT:
A watercraft control system is provided in which shift and thrust of outboard motors can be controlled through adjacent two operating levers in the watercraft having three or more outboard motors mounted in parallel on a transom plate. The control system can be provided with a control circuit for detecting lever positions of the operating levers and controlling the left unit according to the lever position of the left operating lever and the right unit according to the lever position of the right operating lever. The control circuit can be provided with a calculation circuit for calculating an imaginary lever position of the middle unit from the lever positions detected.
