Abstract: A throttle assembly for an engine may include a remote throttle lever, a sensor, and a terminal. The remote throttle lever may be coupled physically to a user input device and operable to be moved under control of the user input device. The sensor is configured to detect a position of the remote throttle lever and generate an output signal indicative of the position of the remote throttle lever. The terminal configured to provide the output signal to a controller of the engine.
