D 2868 (V8) / D2862 (V12) for “Light Duty”

In addition to maintenance visits for clocked hours of operation, there are maintenance steps that are crucial at chronological intervals, regardless of how many hours your vessel has clocked on the water. This includes required marine diesel engine maintenance at one, two, and four-year intervals. Sometimes, maintaining diesel engines can be simple when operating hours and chronological maintenance coincide. allowing our professionals to take care of all your vessel’s maintenance procedures in one visit. Simple, regular maintenance is the easiest, quickest and cheapest way to avoid problems and accelerated engine wear. Most expensive repairs start from a lack of basic maintenance or ignoring small warnings. MAN Marine Diesel Maintenance Schedule.

Marine Diesel Engine Maintenance:

Regular Oil Changes

Most owners understand that frequent oil changes are a must. The typical interval is every 100 hours, but this varies from as few as 50 to as many as 200 hours (small engines like my 1.6 Liter Yanmar take only a small quantity of oil, and need more frequent oil changes, in this case, every 50 hours).

Delo 400 4-stroke oil is suitable for both gasoline and diesel engines. Oil in a diesel works hard—much harder than in a gas engine—because the engine works at a high temperature and under extreme pressure. Diesel oil also contains traces of sulfur, especially in countries other than the U.S., which gets transformed into destructive sulfuric acid inside your engine.

Also, many boats, especially small cruising sailboats, operate their engines infrequently and for short periods of time, when pulling into or out of their slip.

They may also run the engine for long time periods at low RPM, for charging battery banks or freezing the refrigerator’s holding plate. Both of these practices are rough on your engine.

The engine doesn’t warm up to operating temperature, causing moisture to condense inside, creating sulfuric acid and also a buildup of carbon.

If this carbon remains inside your engine, the lubricating ability of the oil is substantially reduced. Plus, this buildup of soot coats valves and valve stems, which reduces the compression of your engine.

Marine diesel engine maintenance. All the experts agree that you should avoid running the engine for short durations and/or at low loads. If you do a lot of this type of motoring, you’re going to need more frequent oil changes with top-quality oil and good filters.
