This motor bypass tool is used to allow you to lower or raise your lift in an emergency then you have a power or motor failure. If you have a c-face motor, this tool will allow you to use your cordless drill to lower your boatlift. You will need to actually remove your motor and insert this tool in the gear box where the shaft of the motor goes. It isn’t ideal but it will get you out of a bind! If you are in a bad situation and short of time you will wish you had one!
