I have just installed a pair of Bravo I's on my 1999 Yamaha OX66's witht he Flo-Torq II Hub assembly kit per instructions; Thrust washer, Drive Sleeve, Prop, Drive Sleeve Adapter, Tab Washer, Lock Nut. As I begin to torque down the lock nut, the prop starts to bind with hardly any torque pressure at all. Have I missed something? Instructions say to torque to 55 lbs. I'm barely past finger tight and the prop binds. Any help would be appreciated.
