Oil lubricated and sea water lubricated stern tube
The stern is the rear or aft part of a ship or boat.
The 'stern'
Lead in stern tube oil analysis typically indicates wear or degradation of components within the stern tube assembly, particularly the bearings or sealing surfaces. Elevated lead levels may suggest that lead-based materials are being worn down, potentially leading to increased friction and eventual failure if not addressed. Regular monitoring of stern tube oil for lead content helps in assessing the health of the propulsion system and preventing costly repairs or operational disruptions.
you get it on the abundened ship from the mt2 room.hope that helps.when you do that you bring it to stern and he will let you traed the scanner for a deepseatooth and a deepseascale.
The ship experiences the most pressure at its stern due to the increased hydrodynamic forces acting on that area as it moves through water. The stern is where the water flow converges after passing the hull, leading to higher velocities and resulting in greater pressure differences. Additionally, the stern's design often includes features like propellers and rudders, which further disturb the water flow and contribute to increased pressure. Thus, the combination of fluid dynamics and structural interactions results in the stern facing the highest pressure.

The stern tube in marine engineering allows the propellor shaft to penetrate the hull of a ship and prevent the ingress of water. It also acts as a bearing and lubricates that part of the shaft.
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 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 stern.
The stern is the rear or aft part of a ship or boat.
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.
