The Ram is the best thing that I have seen. I had this on my last boat and it was great. It may be a little expensive, but it is cheeper then replacing a trolling motor
The one that Bob posted is the same one that I have, Works great. I have a 60 inch shaft on a 16.5 foot boat if it was not for that Ram mount I am sure that the trolling motor would be at the bottom of Mille Lacs.
