Yamaha Outboard Not Running At Full Power

1. Check Injectors

If you’ve had the motor for a long period, then there is a good chance that your unit is struggling to maintain full power because of clogged injectors. Having clogged injectors is quite damaging to the performance of the unit as you won’t ever get the desired efficiency of your system. So, if your Yamaha Outboard is not running at full power, start the inspection with the injector section.

From the quality of the fuel to the maintenance of the unit, a lot of factors can contribute to issues with the fuel injectors. So, if you have not cleaned the injectors in a long while, now is a good time to do so. Ideally, the power issue with the Yamaha outboard will be fixed after you clean the fuel injectors.

2. Replace Fuel Filter

Along with the injectors in your outboard motor, clogged filters can also lead to a similar problem with the power. So, if you’ve not replaced the fuel filters in a long while, then that is probably why the Yamaha Outboard is not running at full power. The filters on your unit are not getting a sufficient amount of fuel to pass through the valve and limit the power output.

To get around this problem, you just have to install new fuel filters in your unit, and that will help you maneuver the power issues in the Yamaha Outboard. Luckily the replacement process is quite easy, and you won’t have to spend more than a few dollars on the new filter.

3. Replace Shaft

If the issue is not related to the fuel supply to the unit, then there is a good chance that your unit has a damaged shaft. In this situation, there is not much that can be done, and you will have to replace the propeller shaft. Unfortunately, the replacement can be somewhat complicated, and you will have to rely on professional help for this troubleshooting method.

So, just call the Yamaha customer support or reach out to your local dealer. Explain the problem to the professionals, and they will help you overcome this problem. Even if your unit is not covered by a valid warranty, you can still rely on help from customer support members to isolate the problem and try to fix it by implementing basic troubleshooting steps. Hopefully, everything will be fixed once you replace the shaft on your unit.
