Abstract

Drive unit for boats comprising an internal combustion engine (16) and an outboard drive (1) driven by the engine. The engine has an engine control unit (13) which holds the speed of the engine constant independently of the load on the engine. A flowmeter (15) continuously gives a signal, which represents the instantaneous fuel consumption to the engine control unit. A trim control unit (11) controls the trim angle of the drive so that the lowest fuel consumption for the set engine speed is achieved.
