Evinrude E-Tec water pump problems is one of the biggest problems that can occur in an evinrude outboard motor.
This is due to the damages it can cause when it occurs.
Some of the water pump problems in an evinrude outboard motor includes low volume of water from water outlet, water pump not pumping water and leakage of water.
When any of these problems occur, it can reduce the volume of water that gets to the outboard motor engine block.
This will reduce efficient temperature control in the outboard motor.
Due to this, overheating can easily occur which will end up reducing the performance of the outboard motor.
To avoid negative scenarios like this, the water pump of the evinrude outboard motor has to function properly all the time.
This will help prevent damage from occurring to the outboard motor due to overheating and also help improve the performance of the outboard motor.
Common Evinrude E-Tec Water Pump Problems
1)Water Pump Not Pumping Water
When an outboard motor is functioning, it is also producing heat also.
This is due to the activities that occur inside the combustion chamber of the outboard motor engine.
Inside the combustion chamber of the outboard motor engine, ignition of fuel mixture occurs continuously.
This is what helps the outboard motor to produce the necessary power to move the boat.
But as this heat is being produced, it has to be regulated.
This is what will help make sure that the outboard motor is functioning well.
To regulate the temperature of an outboard motor like the evinrude, a water pump is used.
This water pump helps in circulating water through the engine block.
This helps in reducing and also regulating the temperature of the outboard motor.
But sometimes, the water pump in an evinrude outboard motor might develop a fault.
One of the ways in which this fault is going to show up is that the water pump will not pump water and circulate within the outboard motor.
When this occurs, one of the ways you can easily detect this is that there will be no discharge of water from the water outlet.
This will easily lead to overheating of the outboard motor.
Due to overheating, the performance of the outboard motor will reduce.
2) Water Pump Releasing Less Volume Of Water
Another evinrude E-Tec water pump problem is seen when the volume of water released from the outlet is very low.
When this occurs, it simply shows that the water pump in the evinrude outboard motor cannot efficiently circulate water within the evinrude engine.
This can be caused by a faulty impeller.
When an impeller is faulty, it will not be able to efficiently circulate Water by pumping it through the outboard motor.
This will lead to a lesser volume of water being pumped to regulate the temperature of the outboard motor.
Due to this, a less volume of water will also be released at the water outlet.
3) Water Leakage
Another type of problem with an evinrude E-Tec water pump is water leakage.
The impeller in the water pump of an evinrude E-Tec outboard motor helps in making sure that water is pumped and circulated within the outboard motor engine block.
But for this to occur efficiently, the impeller has to be properly housed.
This is made possible with the use of an impeller housing.
The impeller housing makes sure that the water that comes in from the water intake is efficiently pumped and circulated by the impeller without loss of water into the lower unit.
But when you start observing that there is water leakage in your outboard motor, you have to troubleshoot the water pump of the outboard motor.
This can be caused by loose seals or damaged impeller housing.
When any of these occur, water will easily leak from the outboard motor water pump.
Causes Of Evinrude Water Pump Problems And Solutions
1)Clogged Water Intake
Before water can be sent to regulate the temperature of an outboard motor, the impeller has to receive water.
It is the water received by the impeller that will help regulate the temperature of the outboard motor.
This water supplied to the impeller is made possible with the help of the water intake.
The water intake is exposed to the water on which the boat moves on.
This helps in pumping water that is lower in temperature to help regulate the temperature of the evinrude E-Tec outboard motor.
But sometimes the water pump may lose efficiency in functioning well.
This can be due to a less volume of water being supplied to the impeller.
When this occurs, it is normally because the water intake has been clogged.
When the water intake of the evinrude E-Tec outboard motor is clogged, the volume of water that the impeller receives will be reduced.
This can be due to obstructions like a seaweed covering the water intake.
Solution
a)Free Stuck Water Intake
A careful physical examination of the outboard motor is always very important before and after usage.
One of the most important parts of the outboard motor to inspect is the water intake.
When inspecting the water intake, it has to be free from obstructions.
This includes obstructions like seaweed and other obstructions that prevent the free flow of water from the water intake to the impeller.
When any of such obstructions is discovered, it has to be removed.
This will help in making sure that an efficient volume of water is received by the impeller from the water intake of the evinrude E-Tec outboard motor.
2) Loose Impeller Housing
For the impeller to function well it has to be in a closed system.
This is what will help it develop some level of pressure to efficiently circulate water within the outboard motor.
For this to be possible, the impeller housing is used.
The impeller housing helps in covering the impeller to avoid pressure loss and leakage.
To achieve this, there are always some screws to help secure impeller housing properly to the lower unit.
But when these screws are loose, loss of pressure will occur.
This will reduce the efficiency of the impeller in pumping freshwater within the outboard motor.
Due to this, you will experience some evinrude E-Tec water pump problems like water leakage, low-volume of water from the outlet valve or even no water release from the outlet valve.
Solution
a)Secure Impeller Housing Tightly To Lower Unit
When the impeller housing is not properly secured to the lower unit, the efficiency of the water pump system will be poor.
This is due to the loss of pressure and loss of water that will occur.
To solve this, the impeller housing has to be tightly secured to the lower unit.
This will help the water pump to function properly without loss of pressure or loss of water due to loose contact.
3) Clogged Impeller
One of the most important components of an outboard motor water pump is the impeller.
The impeller helps in pumping and circulating water from the water intake within the outboard motor.
As the service life of the outboard motor keeps increasing, some particles that the impeller receives from the water intake will keep on building up.
When they are much, they will impede the free movement of the impeller.
This will reduce the efficiency of the impeller in easily pumping water within the outboard motor.
Solution
a)Free Clogged Impeller
When you discover that the water pump in the evinrude E-Tec outboard motor is not functioning properly, a troubleshooting is necessary.
To perform an efficient troubleshooting, the impeller housing has to be opened to inspect the impeller.
If it is discovered that the impeller is being clogged with dirt, the dirt has to be removed.
This will help the impeller to move freely and efficiently pump water within the outboard motor thereby regulating the temperature of the evinrude outboard motor.
4) Faulty Impeller
Another evinrude E-Tec water pump problem occurs when the impeller is faulty.
When an impeller is faulty, signs like wear and tear will be discovered.
This wear and tear in the impeller will reduce the efficiency of the impeller.
Due to this, the cooling process of the outboard motor will be affected.
when the impeller is faulty, the evinrude outboard motor will not be able to pump water.
Solution
a)Replace Faulty Impeller
When you discover that the impeller in the water pump of an evinrude E-Tec outboard motor is faulty, it has to be changed.
In changing it, an original one should be used.
This will help in making sure that the water pump functions properly.
5) Loose Contact Of Impeller With Driveshaft
For an impeller to pump and circulate water within an outboard motor it has to receive energy from somewhere.
This is what will help the impeller to function properly.
For an impeller to rotate, the driveshaft performs the biggest role in this.
When an outboard motor is functioning the drive shaft helps in transmitting rotational power from the outboard motor engine to the lower unit.
Apart from transmitting power to the lower unit, the driveshaft also helps in spinning the impeller.
This is because the impeller is attached to the drive shaft.
As the drive shaft rotates, the impeller also rotates.
But for this to be possible, the impeller has to be securely connected to the drive shaft.
This is made possible with the help of a small pin.
Without this pain the contact between the impeller and the driveshaft will be loose.
This will affect how the impeller will function when the drive shaft is rotating.
Solution
a)Secure Impeller Tightly To Driveshaft
To ensure that the impeller is working properly, it has to be securely connected to the drive shaft.
If it is observed that the contact between the impeller and the drive shaft is loose, it has to be corrected.
This can be due to unavailability of the pin that secures the impeller to the drive shaft.
To solve this, the pin has to be replaced to ensure good contact of the impeller to the drive shaft.
This will help in making sure that the impeller functions properly when the drive shaft is rotating.
This is one of the ways of solving evinrude E-Tec water pump problems when it occurs due to loose impeller contact with the driveshaft.
