Diesel engines for marine boats are reliable, but these systems are not infallible. If the engine in your boat is neglected, it will experience accelerated wear and eventual failure. Also, your engine can break down due to unexpected incidents during operation. Under ideal circumstances, you should consult an expert in marine diesel engine repairs for assistance. However, if you can identify the problem, you might be able to resolve it without a professional. Here are some of the common problems and possible tips for repair and restoration.
Boat Engine Overheating
You should examine your diesel engine with care if the component keeps overheating. The cause of the excess heat will determine the best strategy for resolving the complications. Often, the overheating can be attributed to the malfunction of the piston cooling components. If the piston rings in the marine engine are damaged or otherwise faulty, they will allow the leakage of combustion gases which in turn will increase the heat in the engine. Replacing the rings should help in preventing the recurrence of the malfunctions. The lack of oil in the components that generate friction can increase the temperature. You should lubricate the vulnerable units regularly.
Engine Failure or Breakdown
If your marine diesel engine is not starting as expected or has broken down, you will need to check the individual components for damage or malfunctions. The failure could be caused by anomalies in any critical part of the engine. However, you should note that, in most cases, the cause of the breakdown is not complicated or hard to resolve. For example, corroded battery terminals will prevent your boat from starting, especially after a long period of disuse. Moreover, blown fuses and breakers in the electrical system might affect boat functionality. You should also take time to check the level of the fuel in case your gauge is broken.
Engine Oil Problems
If your engine is not operating smoothly or has shown signs of stalling, the problems might be linked to the condition of the engine oil. The deterioration of engine oil causes most of the inexplicable issues in the operation of marine boats. Therefore, you must be diligent in checking the levels of your oil. You must ensure that the fluid is at the recommended levels. The oil must never fall below the recommended level or be in excess. You should also examine the condition of the oil. If the colour, texture or odour of the oil is unusual or there are foreign particles within, you must replace the fluid immediately.
