ABSTRACT:
Outboard drive for boats, including a gear housing, an underwater housing connected rotatably to the gear housing, and a mounting element arranged between the gear housing and the underwater housing for mounting the drive in a boat hull with the gear housing on the inside and the underwater housing on the outside of the hull and including an exhaust passage with an exhaust outlet. The exhaust outlet is surrounded by a plate made of polytetrafluoroethylene fixed on the underside of the mounting element. The underwater housing is rotatable relative to the gear housing by an electric servomotor communicating with a control computer, which communicates with an engine control computer for an internal combustion engine connected to the drive and is arranged so as, when the engine is shut off, to give a signal to the servomotor to put the underwater housing in a position corresponding to moving straight ahead.
