A boat auxiliary propulsion unit 10 adapted to be connected to the outside of a boat hull, preferably at the aft end and preferably below a swimming platform at the transom of the boat. The unit comprises a watertight housing adapted to be retrofitted to an existing hull, an electric motor within or connected to the housing, a propeller 22 connected to and driven by the motor to propel a boat and a battery 26 able to store electrical power and supply it as required to the electric motor. The propeller 22 may have a silencer and may protrude from a cut away section 24 of a base-wall 17 of the housing. The unit preferably has neutral buoyancy and a connection in the housing to interface with an external electric power system. The housing can contain means to alter the speed or direction of thrust of the propeller and it may also have a removable lid 18. A generator 27 may also be located in the housing to supply electricity to the batteries or power the motor, the generator itself may be connected to an external fuel supply and breather.
