Most 12 volt windlasses have a reversing motor. All that is needed are additional controls. To determine if your motor is reversible, check to see if there is an additional terminal that is not being used. If you have a two terminal motor you will need to purchase a Reversing Kit which contains an additional foot switch and a reversing solenoid assembly.
Windlasses that run on A/C power can be reversed by purchasing a reversing controller and additional foot switch.
Older model BHW and most horizontal windlasses cannot be reversed without changing the gearing.
See "Identifying your Windlass" and call the factory. 401-884-2550.
