A tractor propeller 27 may be driven from the engine 12 through a clutch 28, or from an independent engine. A second driving- propeller 35 is arranged in front of the rudder 40 and driven by bevel-gearing 21, 23 and chain. gearing 33. In a modification, the tractor propeller 27 may be driven from the engine 12 through friction cones 51, 54, Fig. 6, when starting, and afterwards through toothed gearing 50, 53, the wheel 53 and cone 54 being, for this purpose, slid on the shaft 52 by an arm 56 and rod or wire 55. The blade arms 25 of the lifting-propeller are secured in caps or plates 26 keyed or bolted on the shaft, as shown in Figs. 2 and 3. Steering.-The rudder 40 is arranged immediately behind a propeller 35 in order to increase the steering effect.
