How To Fix Small Issues In Yamaha Outboard?

Outboard motors are machines that are fixed on supports that are located at the rear (stern). They are internal combustion engines with a single propeller. Like all internal combustion engines, these machines need maintenance and repairs. The most common problems found in these Yamaha outboard engines can be detected with a multi-meter. 

Why Do We Require Yamaha Motor Service?

The standard reason when an outboard does not start is that the gas supply does not go well. The problems can be various and varied, from the broken starter rope, a pearl spark plug, a severe mechanical problem in the gears or a leak due to lack of oil.

You may seem silly, and yet it can be the cause of everything. If you take gas for good and it is in poor condition, it can drive you crazy and fail to find a solution. No matter how much you disassemble and ride the entire engine. When in doubt we should discard old gasoline and go for a few liters of new gas.

When removing the cap from the tank, it does not hurt to take a look inside. If we observe some suspicious particles floating, do not doubt this gasoline is in poor condition. We must empty it in a disposable canister and discarded and take it to the white point, but never throw it into the sea.

 

Make sure the tank has enough fuel. 

• Remove the spark plug cover from the outboard motor. 
• Take out the wires. 
• Unscrew the spark plugs and set them aside. 
• Examine the bottom should be wet with fuel.
• If it is not, there may be a blockage in the fuel system. 
• Check the fuel line or pump if you have a remote configuration of the tank.
• If the spark plugs are covered with black coal or oil, they may not be working well. It may not be adequate, and they are being used in an engine that gets too hot to work. It could also be that the engine has been running for a long time with the wrong amount of fuel and oil mixture. 
• If your engine has more than one spark plug and only one is dirty, the cause is a weak spark in the ignition system.

Check the operation of the spark plugs. 

Clean the old spark plugs or their connectors with the sharp end of a pin, scraping the carbon deposits that have formed in the insulator that covers the central electrode of the spark plugs. Scrape between the insulator and the wall to remove carbon. Use paint thinner. Put on rubber gloves to protect your hands. Turn the spark plugs in the tank. Clean with a paper towel. Let it dry in the open air.

Sometimes the outboard goes to the bottom of the sea when trying to mount it, or for a mistake, you can try to recover with a while of “fishing”, or diving, and after these recovery tasks, we get it back to the surface. However, naturally, the engine refuses to start. In this case, we should take it to a professional Yamaha Outboard repair.
