I am having difficulty with the location of my boat on the trailer. It is a 1980 17' Bumblebee bass boat, the trailer is a regular drive on trailer. The boat goes against the spare tire and the tip of the boat also rests against the winch when fully loaded. The boat is in position with the bottom rollers. The arm with the wheel that helps guide the boat in position looks like it has been modified longer to help this problem, but it seem to still have a problem. Any help would be greatly appreciated. I'll try to attach pictures a little later. Thanks in advance!
