As you continually make use of your Evinrude outboard motor, some parts will depreciate in performance.
One of the ways it will show up is in having Evinrude etec fuel pump problems.
Some of the problems with Evinrude etec fuel pump include low volume of fuel output, silted fuel pump and malfunction of fuel pump electrical system.
Due to this, the overall performance of the Evinrude motor will be really reduced.
But when this happens, you do not need to panic too much.
What you have to do is to make sure that you troubleshoot well to know the cause of the problem.
In this guide, you will learn of the causes of fuel pump failure in Evinrude and also learn of how to fix it.
Common Problems With Evinrude Etec Fuel Pump
1) Low Volume Of Fuel Output
When it comes to the parts of an outboard motor, there are functions that each of the parts perform.
With this, they are made to function optimally when they are in a good condition.
But when they malfunction or have a problem, they will not be able to perform as they should.
Such problems also happen to the fuel pump of an Evinrude etec outboard motor too.
With the help of a fuel pump, the engine of the outboard motor is supplied with fuel.
The fuel pump does not just supply fuel to the engine, but it makes sure that it supplies the right volume of fuel at the needed pressure.
This is because when the engine is performing, it will consume different volume of fuel at different performance level.
When it is driving slowly, it will not require much fuel.
But when the outboard motor is accelerating, it will require more volume of fuel to burn in order to produce the needed amount of power from the outboard motor.
What controls this volume of fuel supply is the fuel pump.
But a problem comes up when the outboard motor fuel pump has an issue.
When this happens, the fuel pump will not be able to feed the engine with the right volume of fuel.
This is one of Evinrude etec outboard motor fuel pump problems which is low volume of fuel supply to the outboard motor
2) Silted Fuel Pump
Another problem the Evinrude etec fuel pump has is blocked or silted fuel pump.
This is always a very serious issue which will make the fuel pump to be totally ineffective.
When the fuel pump is silted by debris, it will not be able to output fuel to the outboard motor.
3) Damaged Electrical System Of Fuel Pump
When it comes to how the fuel pump functions, it relies on its electrical components to function well.
This is because the fuel pump output fuel with the needed pressure.
This is what helps in feeding the outboard motor with the right volume of fuel.
But these parts cannot last forever.
At one point, they will fail and this will cause a problem in the functionality of the fuel pump.
When this occurs, the fuel pump will not be able to output the right volume of fuel to the outboard motor.
Electrical failure is one of Evinrude etec fuel pump problems that occurs.
Causes Of Evinrude Etec Fuel Pump Problem
1) Bad Quality Of Fuel
In keeping your automobile functional, the use of fuel is necessary to power the outboard motor.
But in using the fuel, you have to make sure that you are using a good quality of fuel.
This is very important due to the benefits that comes with making use of a good quality fuel.
A good quality fuel will help the fuel pump to last longer as well as prolonging the lifespan of the outboard motor.
When you make use of a poor-quality fuel, the fuel pump and the outboard motor will be affected.
A poor fuel quality is one of the causes of Evinrude etec fuel pump failure.
2) Low Quality Of Fuel Pump
When you make use of a good and original part like fuel pump, you will enjoy the benefits.
One is that your outboard motor will function well.
Another is that the longevity of your fuel pump will be high.
But if you make use of a fuel pump that is fake or bad, the fuel pump will easily develop problems.
3) Wrong Capacity Of Fuel Pump
For every outboard motor, there is a rated capacity of the outboard motor.
This capacity also affects the other components that the outboard motor uses.
This includes components like the number of cylinders it has as well as the capacity of the fuel pump of the outboard motor.
Having the right parts is what will help the outboard motor to perform well.
This is also applied to the capacity of the fuel pump.
If you use the fuel pump of a 3hp to run a 100hp outboard motor, the fuel pump will easily damage.
This is because the fuel demand capacity of the 100hp engine will not adequately supplied by the 3hp capacity engine fuel pump.
This will cause an extreme strain on the 3hp fuel pump.
Due to this excess stress on the fuel pump, the fuel pump will be destroyed.
This is one of the Evinrude etec fuel pump problems that exist when the wrong fuel pump capacity is used.
4) Water And Contaminants In Fuel Tank
When you make use of a bad fuel to run your Evinrude outboard motor, you will eventually have some issues with your outboard motor.
One will be that your engine longevity and performance will be affected.
Another is that the fuel pump you make use of will also be affected.
One of the ways this will happen is that the bad fuel will contain contaminants like water and debris that will end up in blocking the fuel pump.
This will cause the fuel pump to be blocked thereby limiting the release of the right volume of fuel to the engine.
How To Fix Failure Of Evinrude Etec Fuel Pump
1) Replace The Faulty Electrical Part
The electrical components of a fuel pump is very important to the proper functionality of the fuel pump.
When it has problems, it will really affect the functionality of the fuel pump.
If the electrical issue is severe after a trouble shooting, then it has to be replaced.
This will help the fuel pump in the outboard motor to regain an optimal functionality again.
2) Unclog The Clogged Fuel Pump
The longer the use period of an outboard motor, the higher the chances of the fuel pump in the outboard motor being clogged.
This is even worse if you are making use of bad fuel with very small and fine size contaminants.
When this happens, the contaminants can easily find its way into the filter of the fuel pump.
As this increases, it will start to affect the fuel pump.
This is because it will end up clogging the filter of the fuel pump.
When you discover that there is a debris in the filter, you have to make sure that you wash the fuel pump well in a clear fuel till the dirt is off.
This will help the fuel pump to function well again and release the needed volume of fuel.
3) Use a Good Quality Fuel
If you want to have a good performance from your outboard motor, you have to be very watchful of the quality of fuel that you make use of.
This will help your outboard motor to perform very well.
A good quality of fuel will also help the fuel pump to function well.
This is because a good fuel is free from contaminants like water and debris.
This helps in reducing the chances of the fuel pump having problems from being silted with debris.
4) Use Right Capacity Of Fuel Pump
For your outboard motor to function well, the fuel pump has a very important role to play.
This is because the outboard motor demands a different volume of fuel at difference performance levels.
This is always made possible by the fuel pump.
But for this to be possible, the fuel pump in the outboard motor has to be of the right capacity.
When it is of the right quality, the fuel pump will be able to output the needed volume of fuel.
But if the capacity of the fuel pump is wrong, there will be issues.
If the capacity of the fuel pump is larger than that of the outboard motor, this can lead to problems.
This is because the fuel pump will release fuel volume too much for the engine to burn off effectively.
This will easily lead to a flooded engine issue.
Also, if the capacity of the fuel pump is too small, it will not be able to supply the needed volume of fuel to the outboard motor.
This will lead to a situation in which the engine vibrates or shuts down due to inadequate supply of fuel.
That is why you need to make sure that you are making use of the right fuel pump capacity in your outboard motor.
5) Replace Faulty Fuel Pump With a Good One
When the problems of a fuel pump is minor, a repair can fix the problem.
But in some of the cases, the damage may be fatal.
In such a case, you have to make sure that you replace the fuel pump with a good one that is new.
This will help the fuel pump to function well again thereby improving the performance of the outboard motor.
This is always the best way to solve Evinrude etec fuel pump problems.
But in making a new replacement, you have to make sure that you are replacing the bad fuel pump with a good and original fuel pump.
This will help your outboard motor to produce a good performance.
