I just purchased the Quick 350 windless for my 2013 22 ft Bennington. I need some help with the installation. I saw a post on this site earlier by a member who installed this unit and am hoping he may be of help on some install directions. Following are some questions I have. > Do you need a anchor rode (chain) with this? > What is the "integrated hydraulic magnetic switch" referred to in the manual? > Is it possible to use one of the unused switches on the console? Or do I need to order this particular switch? I would sure appreciate any help as I am obviously unskilled at this. Thanks Chuck
