Abstract
A usage management system includes a use rights management server and a user terminal. A controller of a vessel propulsion apparatus operates a prime mover in a permission mode to permit an output exceeding a predetermined limit output if use permission is provided from the user terminal, and operates the prime mover in a non-permission mode to prohibit an output exceeding the predetermined limit output if use permission is not provided from the user terminal. The user terminal enters an active state to allow issuance of use permission if a use-permission notification is received from the use rights management server, and enters a non-active state to prohibit issuance of use permission if a use-permission notification is not received from the use rights management server. The use rights management server transmits a use-permission notification or a use-non-permission notification in accordance with use rights information concerning the vessel propulsion apparatus.
