Diesel outboard motor vs. gasoline outboard motor

Index

A petrol outboard motor is often chosen instead of a diesel outboard motor. Petrol engines are much better known in pleasure boating, while diesel engines are less common. However, diesel engines are still used in commercial shipping. What are the differences between these two types of outboard motors and what are the advantages and disadvantages?

Difference between petrol and diesel

If we look at the fuel itself, there is a difference in ignition mechanism. In a petrol outboard motor, the fuel is ignited by the spark plug. This works slightly differently with a diesel outboard motor. In this case, the fuel is ignited by self-ignition.

There is also a difference in the use of both fuel tanks. For example, a petrol outboard motor is much more used for boats that make long trips or want to reach high speeds. But petrol is also frequently used for normal pleasure boating. Diesel engines, on the other hand, are better suited for larger boats that require more power and torque, such as commercial shipping. They usually have better fuel economy and a longer lifespan. They are also safer with regard to fire hazards because diesel fuel has a higher ignition point than gasoline.

Advantages of petrol and diesel

Both petrol and diesel engines have a number of advantages. We list the benefits for you.

Advantages of petrol outboard motors

Gasoline is by far the most commonly used fuel. We distinguish between 4-stroke and 2-stroke petrol engines, with 4-stroke engines increasingly becoming the standard. A number of advantages of petrol outboard engines compared to diesel engines:

  • A petrol engine is suitable for almost any boat.
  • A gasoline outboard motor is powerful.
  • Gasoline is easy to refill along the way.
  • There is a lot of choice in power.
  • Gasoline engines are often lighter in weight.
  • They are easier to maintain.
  • They are affordable.

Advantages of diesel outboard engines

Diesel outboard motors also have a number of advantages over petrol engines:

  • Diesel engines are more suitable for commercial shipping or large boats that need more power and torque.
  • Diesel engines have lower fuel consumption.
  • They have a longer lifespan.
  • They are less fire hazard.

Disadvantages of petrol and diesel

In addition to the many advantages that both fuel tanks have, there are of course also disadvantages that you can consider.

Disadvantages of petrol outboard motors

  • A petrol engine requires more maintenance as it ages.
  • A gasoline outboard motor produces more exhaust gases.

Disadvantages of diesel outboard engines

  • A diesel outboard motor is much heavier than a petrol engine.
  • A diesel engine is much less suitable for water sports.
  • A diesel outboard motor produces more vibrations and noise.
  • A diesel is often not profitable enough for pleasure boating due to the higher purchase price and a small number of sailing hours.

Top brands of outboard motors

Outboard motor maintenance

Outboard motor maintenance is important for longevity, operation and safety. It is best to carry out maintenance immediately after the sailing season. You can also carry out maintenance just before the sailing season. Think of changing the oil, checking the spark plugs, checking the impeller and more. You can do maintenance yourself, but you can also contact the professionals at WorldOfOutboards.com.

Buying a new outboard motor?

Do you want to buy a new outboard motor? Then carefully consider whether you go for a diesel or petrol outboard motor. If you sail for pleasure, it is better to go for a petrol outboard motor. A diesel outboard motor is especially suitable for large and heavy boats that sail a lot, for example commercial shipping.

For petrol outboard motors you can go to WorldofOutboards.com. We have outboard motors from the brands Yamaha, Suzuki, Tohatsu, Honda and Mercury. When you purchase a new outboard motor you get a 6-year warranty, with a second-hand motor this is 1 year. The outboard motor will be shipped to your home within 2-5 working days.
