1. Fuel Pump Problems
The most common issue that users report about this engine is that the fuel pump will give out at random intervals. Now, it can be quite difficult to deal with this issue when you’re traveling far from shore. If you’re in a similar situation and the engine is not performing in a smooth manner, then you’ll have to address this issue with the fuel pump.
Luckily, when you’ve isolated the problem with the fuel pump, it is quite easy to replace. On top of that, you won’t have to set aside a huge amount of money to purchase a pump replacement for your outboard. So, just go to your nearest dealer and purchase a pump replacement. After the pump has been replaced, you won’t have to worry about the same thing again.
To avoid this problem in the future, make sure to use fuel stabilizers and high-quality options. Otherwise, you will be running into the same problem over and over again. It is true that purchasing stabilizers and high-quality fuel is expensive, but you will destroy your engine if you try to purchase cheaper options.
2. Fuel Injector Problems
Similar to the fuel pump, you’ll likely run into problems with clogged fuel injectors if you ignore maintenance requirements for too long. The good thing is that in most cases, the issue is not too severe. You should be able to overcome the problem by adding a bit of fuel injector cleaner into your unit. So, make sure to clean the fuel injectors immediately if you believe that your system is clogged.
While the treatment is relatively easy, you will still need to set aside a good amount of time. That’s because you have to run the injectors after removing the complete assembly separately. So, if you’re inexperienced, make sure to involve experts to minimize errors. Otherwise, you will end up spending hours in the cleaning process, and you won’t get anywhere with the injector problem.
After cleaning up, the injectors make sure to secure every component back in its place and try starting the engine. You won’t have to struggle with the same issues again, and the outboard will run perfectly. With that said, you won’t have to spend as much time on these issues if you follow a monthly maintenance cycle. So, make sure to take some time and service the outboard engine at least once every month.
