Preventive Maintenance 

The maintenance system for MTU products is based on a preventive maintenance concept. Preventive maintenance permits advance operational planning and increases availability. The maintenance schedule is based on the load profile / load factor specified below. The time intervals at which the maintenance work is to be carried out and the relevant checks and tasks involved are average values based on operational experience and are therefore to be regarded as guidelines only. Special operating conditions and technical requirements may require additional maintenance work and/or modification of the maintenance intervals. To perform the individual maintenance tasks, maintenance personal must be qualified to match the complexity of the respective tasks.

Avoid Misinformation 

Contacting the wrong service provider outside the official network can lead to incorrect information. A different service plan can concern the same model of engine but will require different maintenance tasks depending on running hours, years of operation, or load profile. This can confuse yacht captains, chief engineers, or management companies, as misinformed recommendations can cause multiple issues, such as: 

  • Incorrect Operations – implementing the wrong MTU maintenance schedule such as not replacing or checking the right engine components at the right time during engine’s life. The result of this oversight is an increase in the risk of mechanical issues during the yachting season causing considerable inconveniences for yacht owners, especially if any problems arise during charter and require downtime. 
  • Excessive Costs – unfair service providers can direct you to follow a more demanding MTU maintenance schedule to increase workload and a more expensive final invoice. It’s completely wrong to recommend that a crankshaft should be inspected every 10 years, yet this is the kind of advice that engineering companies have been giving their customers… This results in unjustified and unnecessary high financial costs for the yacht owner. 

You must ensure you only listen to official MTU dealers for your yacht engine maintenance recommendations. These will be accurately based on your MTU model’s matrix number helping you avoid these issues.

MTU Maintenance Schedule 

Looking at two different MTU maintenance schedules for a 12V2000 M51A generator running for 3,000 hours  


This schedule shows that in addition to some basic operations in orange, the engine requires a replacement of injectors and recommends a boroscopic inspection in blue which will generates a significant cost.

This second MTU maintenance schedule matrix indicates that only basic operations with the replacement of air filters in orange is needed at a really cheap cost, with the replacement of injectors in blue having to be performed after 4,000 hours of running time.  

In extreme cases, for the same MTU yacht engine based on these two maintenance schedules, the TBO (Time Between Overhaul) is also different. For the first matrix, the TBO or complete engine overhaul is recommended after 18,000 hours of running time or 18 years, and for the second, the overhaul is recommended after 24,000 hours or 18 years.  

To avoid confusion, misinformation, and unnecessary costs, make sure that you contact an official MTU dealer, like NAVIGAIR. We will provide you with accurate guidance and support, ensuring that the correct schedule for your yacht MTU engine is followed.

MTU Emission-Certified Products 

As part of your MTU engine maintenance, there are certain specifications surrounding emission-certified products that you have to follow, and ignoring these requirements violates statutory regulations. The modification or removal of mechanical or electronic components, installing additional components, or the execution of calibration processes that might alter the emission characteristics of the product, are all prohibited by emission regulations. You can only replace or repair emissions-related components if they are MTU-approved. Components such as control units, sensors, cylinder heads, injectors, or exhaust flaps, can be serviced as long as they follow the correct regulations. Failure to comply with these regulations can lead to significant legal and operational consequences.
