The challenges brought on by the marine environment means that you will need to conduct regular maintenance, replacements and repairs on your diesel engine.

 

The good part is that all modern engines have the same sort of needs. They need fresh air, filtered fuel and appropriate coolant and lubricant levels to function. Other than these specifics, as marine engines differ largely manufacturer-to-manufacturer, you may need to consult manuals before proceeding with maintenance.

 

With the help of leading marine engine spare parts supplier, Evernew Marine, this article sheds light on some of the simplest maintenance tips for your diesel engine:

Changing Oils and Oil Filters

  • As marine engines differ largely based on the model and manufacturer, it is a good idea to start with consulting the recommendations to identify the service intervals.
  • If your marine engine doesn’t have a gear filter, it may have a screen element that needs to be cleaned every now and then. Be sure to clean it when changing the gear oil.
  • It is a good idea to change the oil every 250 hours of usage. Some professionals advise changing the oil at least once a year, but it largely depends on the nature of usage.

Inspecting and Changing The Fuel Filters

  • The secondary and primary fuel filters should always be changed at the same time.
  • If you don’t change the fuel filters when needed, it might lead to premature aging of the engine and also other signs of damage like smoking.

Coolant and Oil Inspections

The coolant and oil levels should be analyzed at least once a year and whenever being changed. Although the frequency of changing these liquids depends on the nature of engine usage, at times, you might need to conduct sampling more often. Once the oil is inspected, a professional can advise you on the best measures to enhance engine performance.

Inspecting Air Filters

  • Air filters should be cleaned and oiled less than 4 times before replacing.
  • If the there is an element in place, it should be replaced and never reused.

Inspecting Zincs

  • Engine zincs tend to wear over time and not replacing them could lead to complications in the raw water system.
  • During each service interval, inspect and replace engine zincs.

Valve Adjustments

  • It is a good idea to stick to manufacturer instructions to conduct valve adjustments.

Inspecting Coolant Levels

  • Stick to your manufacturer’s instructions when replacing engine coolants.
  • Using a coolant that doesn’t comply with manufacturer instructions could lead to deterioration of internal cooling system components, like the housing and pipes.

Maintain Accurate Records

  • The simplest way to get to know your marine diesel engine is by maintaining records of all engine activities, service and repairs.
  • Also record marine gear pressures and the temperature at various RPMs. Engine load and fuel burn percentages also matter.
  • Do the same with coolant and engine oil levels.

The bottom line is that you should always stick to manufacturer instructions and recommendations for your specific engine model. Keeping a track of all that you do to the engine, along with all engine readings will eventually help you get the best performance from your diesel engine.
