Frequently Asked Questions (FAQs)

How Often Should You Change Spark Plugs on Yamaha Outboard?

You should change the spark plugs on your Yamaha outboard whenever they get damaged or worn out. However, you might also need to replace the spark plugs after every 3000 hours of usage. It has been proven that the spark plugs on the Yamaha outboard started to malfunction after this certain period, no matter how carefully you use your speedboat.

What Are the Symptoms of a Bad Spark Plug in an Outboard Motor?

You should know properly about bad spark plugs, as you might need to replace them anytime. In most cases, if the spark plugs on your outboard motor seem worn out, it is a key indication that the spark plugs have gone bad. You will also find it difficult to start the outboard motor. In addition, the performance of the motor will be dramatically increased.

Are Yamaha Spark Plugs Pre Gapped?

Depending on the motor to use, most of the Yamaha spark plugs are pre-gapped. This means they are pre-measured for working in different engines. Gone are the days when people gap the spark plugs and considering the current scenario, we. in most cases, don’t need to gap the spark plugs anymore. No matter if we have Yamaha or other spark plugs.
