If you are looking to purchase a new motorboat or you need to replace the old motor on your current boat, you might be wondering how to select the right outboard motor series. Outboard motors possess a range of options, from the two-stroke engine to the four-stroke engine and direct fuel injection to the electronic fuel injection. Here are some considerations to remember while selecting an outboard motor for your boat.
Should I buy a two-Stroke or a four-Stroke Engine?
A two-stroke engine was the go-to for the outboard motor series. Usually, two-stroke engines are lightweight and have had an excellent regulated response, whereas four-stroke engines have provided a cleaner, more advanced performance. As conservational standards have changed and boaters look for a clean, well-organized boat engine. The modern outboard motors have grown — narrowing down the differences between two-stroke and four-stock engines.
Two-Stroke Engines
Two-stroke boat engines burn a mix of oil and gasoline. Earlier, an injector or carburetor nourished the mixture into the engine cylinder through a consumption valve. It led to many fuel escaping, as the exhaust valve endured opened while processing. However, nowadays, two-stroke engines have been intended to prevent this fuel loss.
Four-Stroke Engines
Four-stroke engines are like your car; they have chambers that burn gasoline and a separate series system to oil the engine with oil. As the pistons move, intake and exhaust take place at various times. Four-stroke outboard motor series do not offer as much power as two-stroke motor engines. However, modern fuel injection structures have led to better fuel economy for four-stroke engines, while manufacturers have advanced the machines to be more powerful.
How Does Fuel Injection Work on Outboard Motors?
Today, manufacturers are building outboard motors that are low-emissions and more fuel-efficient due to modern fuel injection systems.
Direct Fuel Injection
DFI, Direct Fuel Injection two-stroke engines feed the fuel combination into the chamber while the piston covers the exhaust valve. It prevents the fuel loss that happened with older boat engines. DFI engines are available in two-stoke and also four-stroke engines. They consume less fuel, have upgraded engine power, and have low emissions. These outboard motor series do not require fuel preparation and are speedy to start.
Electronic Fuel Injection
With EFI, Electronic Fuel Injection, engines, the fuel mixture is injected into each chamber’s incoming air beforehand it reaches the intake valve. Then the fuel spray cools the intake valve, increasing vaporization before it comes to the burning section. A spark plug burns the fuel and air combination. Electronic Fuel Injection engines do not need fuel priming and have low emissions. Moreover, they are quick to start and have lower fuel consumption without sacrificing performance.
Are There Electric Outboard boat Motors?
There are electric outboard motor series available, and they are a good fit for smaller boats or those who love inland fishing. Electric outboard motors are light, tranquil, and need low-maintenance. You have to replace the battery after few years. In this type of electric outboard motors, you will save by fueling cost.
As outboard motor designs evolve, there are many options available. You can be better prepared to select the right outboard motor for your boat with a little information.
