It is important for you to regularly keep up with your diesel engines maintenance so that these problems don’t arise out of the blue. Read on if you would like to learn more about how to maintain marine diesel engines.

If your marine diesel generator is constantly overheating, it may be time to step back and examine the problem carefully. There are a number of reasons that it can get overheated such as:

  1. The piston cooling system failing to perform adequately which can lead to temperature rise.The piston rings of your marine diesel generator may have inadequate clearance or could be broken down and seized. Ring fault or failure can lead to leakage of combustion gases past the piston resulting in an increase of heat
  2. The lubrication system might be failing which can lead to overheating due to friction
  3. There may be valve timing issues resulting in poor combustion

There could be a number of reasons why your diesel engine is failing. The best way to diagnose the problem is the check each part of it. Check for any blown fuses or breakers and make sure your battery terminals are not corroded.

Check your fuel level with a dipstick, it could be that your fuel gauge is faulty. However, if you have tried to substitute a cheaper fuel for your diesel engine recently, this may be causing the problem. Always purchase the recommended fuel for your engine.

Water leakage on your boat is most probably not due to an issue with your marine diesel engine. It is a common issue though and can happen due to many reasons. If you have a newly installed part of your boat make sure that you have not made any mistakes during installation. Shaft seals have a complicated installation process and mistakes are common. Check your installation manual and ensure that hose clamps are tight and each part has been secured in the correct place.

Many of the problems you encounter with your diesel engine may be due to your engine oil. Wondering how to maintain marine diesel engines? Check your engine oil regularly. Take note of the level, make sure it is not too high or too lower as either can lead to very expensive repairs. Check the colour, smell and texture of the engine oil. If there are any foreign particles the oil may be contaminated or this could be an indicator of a metal part failure.

Coolant leakage is a common problem that can occur with all marine engines. It is important to address the problem immediately before it leads to a complete engine failure. When you check your coolant level, make sure the engine is NOT hot as this can lead to burns. Check the hoses for any punctures or issues that may be preventing adequate flow. Tighten your fittings to make sure they are not causing any leaks.

Make sure the gases from your exhaust are clear. Different colours may be an indicators of problems with you marine diesel generator. White smoke can indicate air in the fuel, dirty fuel or a water leak. Black smoke could be the result of a faulty fuel injector, overloaded engine or restricted air supply. Blue gases may be caused by excess oil in the crankcase, an overfilled air filter or worn out parts.

Most diesel engines will come with a troubleshooting manual that addresses most of the common issues you may encounter. If you still have yours lying around somewhere, it’s worth digging it up and having a look. Specific diesel engines may have more complex repair instructions, so it is important to make sure you are getting to right tips for your diesel engine.
