Regular maintenance of your marine engine is essential to guarantee its performance, durability and avoid unexpected breakdowns. At Nanni, private and professional customers can benefit from a whole range of complementary services, such as after-sales service, spare parts service and several levels of coverage for their equipment.

1. Why is regular maintenance important?
Rigorous maintenance of your engine will:
- Extend its life and maintain its performance.
- Avoid costly and unexpected technical breakdowns.
- Maintain the manufacturer’s warranty during the 2-year contract period.
- Maintain your extended warranty: Nanni has created the CARE+3 extended warranty program for pleasure applications, which extends the coverage period of its products. With this additional coverage, Nanni customers can benefit from three additional years of warranty.
2. Essential pre-season checks.
Before resuming sailing, it’s crucial to check the maintenance history and perform certain checks.
In order to draw up an inventory of maintenance already carried out on a used boat, you can consult the engine maintenance logbook, or ask the previous owner directly for the operations carried out in previous seasons. This will enable you to plan for future work and keep track of maintenance.
These preventive maintenance operations, in line with the maintenance intervals, can be carried out by the engine owner/operator or by a Nanni dealer. These checks are essential to anticipate any anomalies and ensure safe boating.
Here are a few regular checks to be carried out, which are generally the responsibility of the user, in particular those performed each time the engine is used:
- Oil level (engine and reverser).
- Coolant level.
- Battery charge.
- Air filter: clean or replace if necessary.
- Turbocompressor: check for oil residues or other liquids.



If you decide not to use the engine for more than a year, there is a specific procedure for prolonged storage (oil, fuel and coolant change). To follow this procedure, contact your nearest authorized agent.
During the warranty period, it is essential to have all work carried out by an authorized Nanni workshop. In addition, all service should be registered in the Nanni after-sales system.
3. Frequency and content of maintenance on a marine engine or generator.
Maintenance must be carried out every year or according to the number of hours of use, following the maintenance log available in the user manual.
To be scheduled every year or every 250 hours:
- Oil change and filter replacement (oil and fuel).
- Replacement of raw water pump turbines.
- Change sacrificial anodes (zinc for sea water, magnesium for fresh water).
Every 2 years or 500 hours:
- Cleaning of cooling system, heat exchanger and aftercooler.
Nothing is better than original parts to take care of your investment.
