Sounds like you might have sheared the drive shaft, try putting it in gear and then turn the prop, it should try to turn the motor when you do if it' free pull the lower unit and pull the shaft and look at it, i've seen the splines twisted like a screw.

Have you checked the shear pin in the prop? Your motor has a pin that allows the propshaft to engage the propeller. If you hit something this pin may have broken, allowing the propeller to freewheel. You can get a new shear pin at your local dealer...<br />- Scott
