A universal steering and propulsion unit for marine craft utilizes a power train which includes a differential gearing unit with control of the power delivered being accomplished through selective braking of one side of the differential. Steering may be accomplished by a 360 DEG rotating ability of the propeller without interruption of the power delivered to the propulsion unit. The power train also provides a special gearing arrangement whereby the propeller drive shaft may be driven so as to provide forward thrust regardless of the direction of rotation of the output drive shaft of the power unit, thus obviating the necessity for oppositely rotating output shafts when dual drive units are required. The oil pressure about the propeller shaft and gear transfer housing is used for feathering the propeller blades.
