Improvements to electrically powered watercraft including kayaks are disclosed. The watercraft comprises a hull defining a cavity and a battery powered retractable propulsion unit. The retractable propulsion unit can be retracted into the cavity with powered or unpowered means. Various retractable propulsion units are disclosed, including propulsion units that are steerable wherein the thrust can be selectively directed. Specific embodiments to improve the steerability of electrically powered watercraft are disclosed. Mechanisms for disengaging the steering controls from the retractable propulsion units are also disclosed. Locking mechanisms for locking the retractable propulsion unit in an extended or fully retracted position are also disclosed.
