In neutral, the propeller shaft is not engaged with any other part of the motor so the prop will spin freely. You'll often see this when a boat is being towed down the highway - the prop is spinning the same as a windmill does in the wind. It's best to let it spin cause if you put the motor in gear and the prop hits something, such as your driveway while you're going in or out of your yard, there is no give and you could damage your prop or worse, the gears inside.

From the pilot's point of view in the front seat of a Piper J-3 Cub, the prop spins clockwise (right).
No, it would spin around and not land properly.

The propeller size on an outboard engine, is dependant on the application. The size of the boat, and more particularly the weight it will carry, determines the propeller size.
Sometimes the center of the prop breaks loose and slips or the splines get stripped. Also check to make sure you have the correct pitch prop for that motor and it is fastened securely.
They do not always "crash" in this manner. although when they do, it is mainly due the instabilization of the tail prop. ============================================================ if the tail prop is not spining the rotation of the main rotor will force the helicopter to spin in the opposite direction, by air drag, the tail counterbalances this force.
