Everything You Have To Know About Outboard Engines

china 4 Stroke outboard motor supplier

The popular types of outboard engines nowadays are the four-stroke and the direct fuel-injection two-stroke. Both of these outboard engines passed strict regulations concerning the engine’s exhaust emission in the US and Europe. Boaters still argument the better choice, but it is a matter of preference. You must do searching and know about both types before going to the 2 Stroke or china 4 Stroke outboard motor supplier. To help you find out which outboard engine can serve you best, read the following. You can read about its pros and cons, top brands, and everything else in between.

Direct Fuel-Injection two-stroke:

To know about DFI, you must know its advantages and disadvantages:

No Oil Wasted

The DFI two-stroke outboard engine is known to burn oil more effectively. Unlike the carburetor two-stroke, there is no hazard of losing 30% of the oil. Therefore, you cannot expose the exhaust valve when the fuel gets into the cylinder.

Great Torque

This DFI two-stroke engine quickly replies when you throttle. It is ideal for water skiing and very helpful when getting ashore fast during a bad climate.


These outboard motors have been around since 1996 and are lighter than a four-stroke outboard. Despite being dated, you can consider these engines to have low emissions.

Disadvantage :

  • Expensive oils
  • Abrupt power surge during acceleration

Good For Fishing Trips

Fishing trips contain cruising for long hours, and this motor can handle continuous stress due to its progressive power and torque. The cruise is a smooth experience as adjustments in the throttle do not result in a burst of energy from the engine.


With proper maintenance, a four-stroke saves up to 40% on fuel. You may notice this more when you run the ship on low rpm and when it is high than a traditional two-stroke engine.


You can separate a four-stroke engine’s power phase from the exhaust, making the explosion almost inaudible. You can find this feature in DFI two-strokes as well, but others claim the four-stroke is quieter.


  • Expensive
  • More parts want maintenance

Things To Do After Every Trip

  • Flush out the engine even if you have avoided saltwater seas and only boating in freshwater lakes.
  • Check the water flow in the pump. When the flushing is complete, detach the fuel line and burn out all the fuel in the carburetor. Then turn off the engine and the battery switch, if you have any.
  • Check the outboard engine cowling for any signs of a leak. If you get one, refer a mechanic.
  • Spray an anti-corrosive coating when you have wiped down all the parts. You must also use a lubricant on all the moving parts.
  • Last, you can cover the engine with plastic or covering.

Regular Maintenance

The more you preserve your boat, the easier the process will get every time you do it. Here are some ways to prevent that.

  • To avoid clogging, check the hoses and fittings to see if it wants replacement.
  • Always find dings in the propeller. Depending on what you see, fix or purchase a new one immediately.
  • Avoid compression by always keeping your fuel topped and using a fuel stabilizer when you add new fuel.
