To reduce weight and for good heat disposal.
why propeller shaft are made hollow
Because the load taking capacity of hollow shaft is more as the load per unit area is lesser due to the lesser cross sectional area.
The spinning shaft from the engine to which the propeller is attached.
Weight savings.

Sometimes the propeller on a boat is called a screw & they used to be made of lead. So they would be found at the end of the propeller shaft.
important reason behind inclining the shaft is to avoid/reduce various vibrations that may come up from the propeller and shaft rotation. various rulebooks have the minimum clearances for hull/propeller, so when the hull and propeller are designed and the minimum clearances are not satisfied shaft are inclined. other reasons include better positioning of engine bearers, better flow angle to the propeller blades

On a ships propeller shaft, the thrust will be in line with the axis of the shaft.
The cone pin, or shear pin, is used to attach the propeller to the drive shaft so that if you hit something hard with the propeller, you only break the shear pin, and not the expensive drive shaft, motor, or propeller.Or, more specifically, that you only break the shear pin and propeller, not the drive shaft or motor.
