Outboard drive unit for boats, including an underwater housing (), in which two propeller shafts () are mounted and are driven via a first bevel gearing () enclosed in the underwater housing, and a second bevel gearing () enclosed in a gear housing (). With the aid of a mounting element () joined to the underwater housing and the gear housing, the drive unit can be mounted in an opening () in the bottom () of a boat hull, with the underwater housing on the outside and the gear housing on the inside of the hull. The mounting element forms a housing which defines, firstly, an oil reservoir () for the oil of the drive unit and, secondly, a surrounding chamber () through which engine cooling water flows and which is used for cooling the oil in the reservoir.
