well they think they found the problem they think 1 drive has 1.50 gears and the other one has 1.65 and considering that its been like that since i bought the boat at the end of last year from a broker and couldnt get much background on it and one of the drives was brand new cpo and doesnt have the nomber on the side they counted the rotation and thats what they came up with there going to go inside it tomorrow to confirm
