It is intended to provide a marine propulsion device information transmitting and receiving system, whereby data related to an engine of a watercraft can be inhibited from being falsified. The marine propulsion device information transmitting and receiving system includes a watercraft and a server. The watercraft includes a propulsion device that includes an engine and a controller that controls the engine and is connected to a communication device. The controller encrypts an operating time of the engine and data related to the engine with an encryption key associated with information unique to the engine. The watercraft further includes a communication device that transmits the information unique to the engine, the encrypted operating time of the engine, and the encrypted data related to the engine to the server. The server receives the information unique to the engine, the encrypted operating time of the engine, and the encrypted data related to the engine, decrypts the encrypted operating time of the engine and the encrypted data related to the engine with the encryption key associated with the information unique to the engine, and determines whether or not the decrypted data related to the engine are genuine based on the decrypted operating time of the engine.
