I just found a used trailer for my 12' jonboat after 6 months of looking. I just finished putting the boat on the trailer today and noticed when I crank it down with the strap up front 2 things happen...(1)the middle roller doent hit the bottom of the boat by about 3inches.(2) The crank handle hits the front of the flatbottom jonboat before I can get the boat all the way up on the front roller. The back bunk boards are perfect?<br /><br />Thanks for any help,<br />Suzuki 40
