No John Cena is not a Marine. But he did go to Parris Island 2 weeks pre-bootcamp to get a feeling of the Marine Corps. He never earned the title of US Marine in my opinion they director of that movie should have chose a real Marine less Marines angry at Cena that way.
No he isn't. He acted in the movie "The Marine" as a marine. In real life he is a professional wrestler, actor and a hip hop artist.
The duration of Baby Blue Marine is 1.5 hours.

In the lower unit or gearbox
a marine gearbox is typically hydraulically operated like an auto car gearbox but will only have one forward and one reverse gear the reduction ratio is dependant on boat size-engine power-engine revs-propellor size and is a calculation best left to professionals
A higher pitch propeller typically gives you more speed because it allows the engine to turn fewer revolutions per minute (RPM) to achieve the same speed. However, choosing the right propeller pitch depends on various factors such as boat weight, hull type, and engine power. It's important to consult with a marine expert to select the best propeller for your specific boating needs.

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.

The Wright brothers conducted extensive wind tunnel testing and research to determine the most efficient propeller design. They also used knowledge of existing marine propellers and their own aeronautical experiments to create a design that would provide the necessary thrust for their aircraft. Their propeller design was based on calculations of thrust, efficiency, and power requirements for their flying machine.
Different kinds of metal can be used in making a propeller. Marine propellers are made from aluminum and stainless steel since they are corrosion resistant.
in air: c * D^5 where c=15 for 3 blades; c=17 for 4 blades and 18 for 5 blades. D=diameter of prop in meters results in kgm^2 BR GDB
MARINE engines are designed to fit into boats and ships for propulsion units. They often drive a crank shaft, or in the case of turbine are connected to a reduction gear, which is coupled to the propeller shaft. Marine engines (piston) are often mounted vertically rather than horizontal to save space. Marine turbines are often smaller for the same horsepower output, and operate at higher speeds than power plant turbines to produce that horsepower.
It uses marine gear oil. This is 80W90 hypoid oil that contains emulsifiers to keep the oil from turning to mayonnaise if a little bit of water gets into the gearbox - and since a little bit of water gets into every marine gear box eventually, you need those additives.
A dumb barge is a type of barge that does not have its own propulsion system and must be towed by a tugboat or another vessel. It is designed to carry cargo or equipment over water and is commonly used in marine transport for bulk goods or construction materials.
