MotorGuide rear electric motor, 36V 109lb. This is a repair shop specification electric motor, allowing forward and reverse operation with the control bar. The shaft length is approximately 80cm, and it's designed to be mounted on various boats, from rental boats to aluminum boats like Stacer. Operation has been confirmed to be problem-free. I am selling it because I no longer use it. I look forward to hearing from someone who can use it.
