How many types of marine engine do we have?
Most modern larger merchant ships use either slow speed, two stroke, crosshead engines, or medium speed, four stroke, trunk engines. Some smaller vessels may use high speed diesel engines. The size of the different types of engines is an important factor in selecting what will be installed in a new ship.
How do I choose a motor for my boat?
The rule of thumb is based on weight alone, and says you should have between 40 and 25 pounds of weight for each horsepower. For example, a 5,000-pound boat could have an engine with between 125 and 200 horsepower.
What kind of engines are used in boats?
It can be seen from the above classification that marine engines are those which are used in marine vehicles namely boats, ships, submarines and so forth. Both 2-stroke as well as 4-stroke engines are used in the marine industry.
What’s the difference between a car and a marine engine?
Essentially, a marine engine has just one gear compared to the four or more that a car engine has. This is another major difference between marine motors and car motors.
How many cylinders does a marine motor have?
This is convenient because you can lift the whole unit out of the water when you winterize your boat. This type of marine motor usually features 2 or 3 cylinders, though you can find it in V-6 and V-8 varieties, as well. Typically, this motor uses the power of jet propulsion to move the boat.
How big is a 2 stroke marine engine?
You can see both these types of engines in the pictures below, the first figure being that of a 2 stroke main propulsion plant while the second is of a 4 stroke generator. Just keep in mind that these images are just for giving you a rough idea otherwise they come in a variety of sizes and flavours.
How is a marine engine different from a truck engine?
Specific marine rated blocks are sometimes casted with more nickel to prevent corrosion. Overall the torque curve with marine engines is different than truck engines. With marine diesel engines they are constantly at 4,500 – 5,000 RPMs for hours on end. Truck engines only sustain high RPMs for a short period before shifting to a different gear.

What is a stroke in a marine engine?
Even being used a lot many times in engineering (Mechanical + Marine). There are always some engineers who remain doubtful about what it is! A stroke in an I.C (Internal Combustion) Engine is the distance traveled by the piston from top to bottom dead center and vice versa.
