Differences Between Marine and Car Engines

If you are repairing your boat, then you may be thinking about changing your old marine motor with a brand-new one. As you look at the engine on the market, you can see that automobile engines are often cheaper than marine engines. So are they interchangeable? And if not, what is the difference between sea engine and automobile engines?

But before starting let us understand what is the marine engine and automobile (car) engine.

Car Engine (Automobile Engine): 

Automobile engines are the engines which are specially made to run a car, motorcycle, trucks and buses. Automobile engines run from a fuel like diesel, petrol and CNG (Compressed Natural Gas) gas. Engines can be used engines or new engines or remanufactured engines.

Marine Engine:

Marine engines are different from the automobile engines. They are those engines which are specially designed to run the boats, submarine, yacht and ships in rivers, lakes, sea and oceans. Similarly, like car engines, they use diesel and petrol to run in the water area.

Differences

They share many of the equal systems and elements, the marine engines and car engines are devised to work in a very varied environment.

At first glance, one of the most noticeable differences among the marine engine and the car engine is the price. There are distinct differences between component parts and systems of marine and motor vehicle engines. Which also accounts for the difference in the cost of the replacement parts between the two parts for the fuel, Cooling and electrical systems of marine engines are expensive.

The marine engines will be subject to the conditions of salt, water, air, rain, sun, sea life, etc., which a normal automobile engine will never face. Therefore, marine engines should be more reliable and sustainable.

You should know about that the alternator, distributor, and starter in a marine engine are separate from the ones in a car engine. In a marine engine, all of these have unique screens which can inject inner sparks so that they do not light the gas fumes in the engine section of ​​the boat after penetrating the atmosphere.

If you try to use an engine that does not have these screens, then you ruin your boat and create a critical condition for anybody nearby.

A car is used every day or at least several times per week. It is good for engines, batteries and other components because they often lose power or become usually weak when they sit for long periods of unused. But many people do not carry their boat almost as often they drive their cars, so it is understood that Marine motors have not been used to make use of the car’s engine. 

There is another difference between the marine engine and the car or automobile engine. You can not purchase the marine engines easily from the market. While this case is not with the car engines.

You can easily purchase the car engines remanufactured engines or new engines or used engines from the market as well as online from the trusted online sellers like AutoTechio at cheap prices. 

So now you can see that there is a substantial difference between Marine engines and Car engines that they are not interchangeable.
