Malfunctioning and diesel engine failures are the most common cause for emergency rescue calls. This is especially true of fishing boats and charters. Most marine engine problems are caused by minor malfunctions that go unnoticed or are completely overlooked.
Fortunately, most common marine engine problems are preventable with routine maintenance. There are also signs to look out for to make sure your vessel doesn’t leave out stranded at sea.
Since a diesel engine failure is generally caused by a number of small malfunctions, it’s usually possible to get the engine up and running again without too much effort. As a rule of thumb, it’s important to remember not to jump to quick conclusions.
Whether you’re a marine engine specialist, diesel mechanic, or an amateur mariner, systematically run through the possible causes. This will save you time and money in the long run and keep you from causing further harm to the engine.
For example, it only takes a moment to use a dipstick to ensure the fuel gauge is accurate. This is more common than you’d think and adding fuel is a lot easier (and cheaper) than performing even minor engine repairs. Here are some more common marine engine problems and quick troubleshooting techniques.
Fuel Valve Malfunction/ Leakage
Check the fuel valve in the fuel system in the event of a sudden temperature change inside one unit. Perform pressure testing and revamp the fuel valve while performing the examination. When a diesel engine is poorly maintained, fuel valve cracks and leakages in high-pressure fuel pipes become more and more likely. Make sure you perform proper, routine maintenance of the fuel oil systems and have it regularly checked to prevent them from occurring unexpectedly.
Air Leakage
Commonly overlooked and underestimated, small air leakage is a simple problem with easy fixes. When the engine is in use, the air system is in an open position. Any sound caused by leaking air will be difficult to overhear. Trace the airlines and feel the connections and joints to detect obvious leaking or deliberately blackout the engine and listen for a hissing sound.
Defective Gauges, Sensors, & Alarms
Any gauges installed on the vessel can become defective from vibrations, bad connections, or other circumstances. Depended on for different purposes, one way to ensure they are not defective is to keep a running log of their readings.
Use the local readings instead of remote readings and include all gauges and meters for optimum results. Replace all gauges if a defective one is discovered.
Make sure to perform routine checks on all sensors to ensure the readings are accurate. Dust, high temperature, and other circumstances can cause inaccurate readings, leading to false alarms.
To prevent common marine engine problems from occurring, have it routinely checked and serviced. Diesel engine maintenance is key to keeping the unit performing as it should and the more disciplined you are in doing so, the less time and money you’ll spend on repairs.
