Gas or Diesel? A Guide to Choosing Your Boat Engine

The engine in your boat affects its performance, cost efficiency, and safety. And before you buy your first boat, you must know when a diesel motor should be preferable, and when it is not. For instance, to think that gas is always expensive in the long run is not quite right because it can be cheaper than diesel fuel in some areas. This is just one example of the factors you need to think about. We” discuss the rest below. 

Consider the Size of the Boat

Powerboats with a size of 30 to 25 feet can only have a gas engine in them, while the 45 feet and bigger boats use the diesel one. The question you should ask yourself now is if you want to prioritize the engine preference or the size of the boat. 

Another insight to have here is the cruising experience you expect to have. A big boat provides more stability and smooth navigation, especially during high winds and harsh tides. It will also be more convenient to sail in an extended period. For further information about this, you should check Sun Power Diesel out.

How Are You Going to Use the Boat?

The main drawback of gasoline engines is that if you rarely turn them on, corrosion develops, and the gears wear out. You need to inspect the condition of gas engines at least once a month. And during winter, you have to make sure that all the seals in the engine are in top condition, or water can enter can break the internal parts. 

A diesel engine, on the other hand, still needs regular inspection as well. But you can get a longer interval than the gas engine. Moreover, diesel engines are superior if you need them to run continuously in a long time. 

Will You Be Bothered with the Engine’s Noise?

But, of course, this additional work requires another budgeting and time allocation. If you can’t afford them, go with the gasoline engine instead. 

Moreover, don’t just claim that your boat is “noisy”. Measure it in decibels with a decibel meter or apps on your phone. 

The Safety Concerns You Must Know

If you have ever heard that gas engines blow up more frequently than the diesel, it’s a myth. In fact, before the invention of water-cooling turbochargers, diesel engines had five-time rates of catching fire than the gas. 

The safety concern that you must be thinking about is carbon monoxide poisoning. Diesel engines produce far less CO than the gas. Therefore, make sure that the air circulation in your boat is regulated well.
