Before taking the measurement, we have to remove the rope guard first.Also to make sure weather the vessel have the Poker gauge or not.This poker gauge is use to measure the propeller shaft drop (known as propeller wear down). After dismantling the rope guard, make sure to turn the blade to one position refer to the marking.Normally, we take top measurement and bottom measurement.
It is a tunnel-like opening at the vessel's stern, through which the propeller or tail shaft passes, in order to connect the propeller to the engine.
The spinning shaft from the engine to which the propeller is attached.

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

The Hunley was a submarine built by the Confederacy during the Civil War. It was propelled by its 8 crewmen turning a crank to which the propeller was attached.
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.
