The stern.
The stern is the rear or aft part of a ship or boat.
The rear of the ship is called the "stern". The front is called the "bow". The rear direction in a ship is "aft". (head "aft" to get to the "stern").
The propeller shaft in a boat engine is fastened to the flywheel by bolts, and it passes through the boat's thrust block and is aligned with the shaft tunnel. It also passes through the stern tube to drive the propeller. The stern tube shaft itself holds the "prop" shaft in place and shut off the open end when it pierces the aft hull. It is commonly manufactured as cast iron and welded into the frame of the stern of the ship.
The bow is the front end of the ship, with the stern being the back end.
