The Newport Tiller Extension Handle is compatible with most outboard motors, including the Newport NT300 and Newport's entire line of trolling motors. The Tiller Extension handle can be easily attached to the existing tiller handle, providing boaters with an extended reach that allows for more comfortable and efficient operation. The Newport Tiller Extension handle is especially useful for boaters who want to improve their control while seated or standing, and it can help reduce fatigue and strain on the hands and arms.
