Here are the common symptoms of the Suzuki outboard boat engine fuel pump failure:
- sputtering engine;
- motor dying unexpectedly;
- serious loss of power;
- hard start;
- uneven work of the motor, strange noises.
If you experience these issues, it's worth checking the fuel pump first. This is a very common issue for Suzuki outboard motors and it's also a relatively easy repair.
Why do these fuel pumps fail?
First of all, the fuel pumps in outboard boat engines fail because of poor fuel quality. It's not always that you buy bad fuel but you may be storing it incorrectly. If you store the fuel for a long time, it loses its properties and may damage the pump.
Also, the metal canister may contaminate the fuel with numerous small metal parts and rust dust. This will obviously affect the pump and lead to its premature death.
The life expectancy of the Suzuki outboard fuel pump is not that long and I should say that a lot of boat owners have this issue and need to replace the pumps once every two seasons or so. So, I can conclude that Suzuki does have faulty pumps.
How to solve the problem?
Here's what you should do if the Suzuki pump fails in your boat:
- make sure that this is exactly the pump;
- make sure you are using the proper fuel - ethanol fuel can kill the high-pressure pumps pretty quickly;
- make sure you have the water-separating filter in the system - water will kill your pump quite fast;
- locate the pressure regulator and make sure it works well - in high-pressure pumps this may be the problem;
- if nothing helps, replace the fuel pump with the new one and make sure you use it properly.
Although Suzuki pumps are not the most long-lasting, they usually die because of several mistakes that owners make when using their boats.
What kills your outboard fuel pump?
There are several things that reduce the lifespan of the pump:
- water in your gas;
- adding oil or additives to gas;
- using poor fuel filters;
- using your boat very rarely (rust occurs in the pump);
- using poor-quality or contaminated fuel;
- installing aftermarket cheap pumps;
- installing used remanufactured or repaired pumps.
Unfortunately, repairing the fuel pump or buying it used will not help you solve the problem for a long time. The repaired pump will rarely last long and will most likely work intermittently causing some minor problems from day 1.
