5,000 hours
The average marine gasoline engine runs for 1,500 hours before needing a major overhaul. The average marine diesel engine will run for more than three times that long and log an average 5,000 hours under the same conditions.
Why diesel engines are used in ships?
Because of their poor thermal efficiency at low power (cruising) output, it is common for ships using them to have diesel engines for cruising, with gas turbines reserved for when higher speeds are needed.
What are the types of diesel engines?
There are three basic size groups of diesel engines based on power—small, medium, and large.
Is there a difference between marine diesel and regular diesel?
Marine diesel oil (MDO) is also composed differently than regular diesel fuel. Unlike the diesel you fuel your car with, MDO contains some heavy fuel oil….

Is there a difference between diesel and marine diesel?
On-road diesel fuel was limited to 15 parts per million of sulfur content while off-road diesel (for boats and generators and other non-road uses) was allowed to be higher sulfur. More sulfur in marine diesel meant better resistance of microbes in storage and improved lubricity of marine diesel fuel.
Which diesel motor is best?
The best diesel oil for an engine depends on the type of vehicle and how often the oil is changed. However, most diesel engine oils should be heavy-duty, fully synthetic products designed with high performance in mind.
Does Detroit Deisel still make marine engines?
Of the five million Detroit Diesel engines produced since 1938, it’s estimated one million are still in service. Detroit Diesel marine engines include both 2- and 4-cycle engines with inline and V-block configurations as well as naturally aspirated and turbocharged air intake systems.
How does a marine diesel engine work?
Gasoline engines and diesel engines both work by internal combustion, but in slightly different ways. In a gasoline engine, fuel and air is injected into small metal cylinders. A piston compresses (squeezes) the mixture, making it explosive, and a small electric spark from a sparking plug sets fire to it.
What is the difference between marine motors and car motors?
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. You should also keep in mind that the alternator, distributor, and starter in a marine engine are all different from the ones in a car engine.
