To provide an underwater scooter capable of realizing on-water navigation and underwater navigation by driving a propeller by an internal combustion engine.
The underwater scooter has a snorkel (48) to communicate the inside of a watertight container (14) to store an engine with the atmosphere, and an air tank (22) in which air to be fed to the inside of the watertight container (14) is sealed. When the underwater scooter (10) is navigating on water, air for combustion is fed to the engine from either the snorkel (48) or the air tank (22). On the other hand, when the underwater scooter (10) is navigating underwater, air for combustion is fed from the air tank (22). A starter grip (92) is attached to an upper end of the snorkel (48) to prevent ingress of water into the watertight container (14).
