A motorized cassette is configured in size and shape to be insertable into a hole in a personal watercraft and provide a propulsion system for the watercraft. The motorized cassette may include a housing defining a water-tight enclosure, an electric motor disposed within the enclosure, a drive shaft disposed within the enclosure, the drive shaft coupled to the electric motor by a belt drive, a flow path having a water intake port and a water exhaust port; and an impeller positioned within the flow path and coupled to the drive shaft. The electric motor may be positioned above the drive shaft in a stacked configuration.

Disclosed herein are electric outboard drive systems configured to be mounted to a transom of a watercraft. In some embodiments, the outboard drive includes a rudder body having a flow path therethrough. The rudder body may also include at least one electric motor disposed within the rudder body. The electric motor may be powered by one or more batteries disposed within the rudder body. The electric motor may be coupled to a drive shaft and an impeller disposed within the rudder body. The outboard drive may also include an air pump disposed within the rudder body. The outboard drive may be used in conjunction with an inflatable watercraft. For example, the outboard drive may be used to inflate and propel an inflatable watercraft.

Abrégé

Disclosed herein is a battery management system. A housing may contain one or more of an electric motor, a battery electrically coupled to the electric motor, and a sensor configured to detect a harmful environmental condition within the housing. Such sensors can detect a potentially harmful condition including but not limited to smoke, heat, water, or shock. A circuit may be coupled to the at least one sensor and configured to uncouple the battery from the motor and discharge the battery when the sensor detects the harmful environmental condition. If a potential problem with the internal environment of the cassette is detected, the cassette batteries can be effectively disconnected with the main output, thus disabling the motors. Furthermore, energy stored in the batteries can be slowly and safely discharged. In some embodiments, when a potential problem with the internal environment of the cassette is detected, the batteries can be discharged and permanently disabled. Illustrative embodiments disclose a battery management system implemented in a motorized watercraft.

A system (2300) for mounting a motorized cassette to a watercraft body comprises a mounting assembly (2311) configured to releasably secure the system to the watercraft body, a housing (2331), a tiller (2301), and a motorized cassette. The housing includes a receiving space and the motorized cassette is configured to be at least partially inserted into the receiving space. Manipulation of the tiller causes rotation of the housing relative to the mounting assembly such that the tiller can be used to steer the watercraft body.
