A manually operable unit having a single handle for driving, steering and tilting a boat propeller. The crank handle, when turned, drives the propeller through bevel gearing. A vertical sleeve surrounding a vertical drive shaft has an offset U-shaped portion terminating in a sleeve serving as a bearing for the crank handle. Pushing the crank handle against the bearing rotates the vertical sleeve which mounts the propeller, therefore steering the propeller. Pulling of the handle will tilt the vertical sleeve with respect to a mounting C-clamp to pivotally raise the propeller.
