Once the prop is off the motor, you can tune it by loosening the 3/8"'bolts a tiny bit. Turn the motor on high speed and gently rotate the housing end by the skeg until the motor is running the smoothest/fastest it can. Tighten the 3/8" bolts back to the same torque they were originally. Don't worry if the skeg isn't exactly straight....it will still work and steer just fine. Only difference is the motor will have less vibration and noise.....and little more power.
Also...invest in a cheap lawn mower blade balancer and balance the prop. Even a brand new weedless wedge 2 needs a little work to be perfectly quiet.
