A boat is equipped with a motor assembly mounted on a housing in the bow of the boat. The housing has a compartment with a bottom opening accommodating a motor and propeller assembly. A mechanism is used to selectively move the motor and propeller assembly out of the compartment below the boat and retract the motor and propeller assembly back into the compartment. A pair of doors hinged to the bow and connected to the motor and propeller assembly are moved to closed positions when the motor and propeller assembly is located in the compartment and located in open positions when the motor and propeller assembly is moved to its down position below the boat.
