The auxiliary drive unit includes a housing slidably supported by the transmission unit, and the housing carries a motor and a drive sprocket driven by the motor. The drive sprocket is hollow, to enable the propeller shaft to extend therethrough. The drive sprocket includes axially facing teeth which are engageable with axially facing teeth of a coupling sleeve affixed to the propeller shaft.
