ABSTRACT:
In a system for controlling a drive unit, particularly a boat drive unit, which comprises an internal combustion engine and a reversible gearing, with an operating member for adjusting the power and the direction of rotation, the operating member (1) feeds electric signals corresponding to the power and the direction of turning to a control device (5) which contains a microcomputer (6). Actuators (11, 12) for the power of the internal combustion engine and the switching of the reversible gearing respectively are connected to the control device (5). The control device (5) is developed in such a manner that switching of the reversible gearing is only possible when the speed of rotation of the internal combustion engine lies below a predetermined value.
