Due to their inertia, hot oils retain a higher temperature of the engine which is not covered by Nanni Industries than expected. A hot oil can cause severe burns on warranty.
On manufacturers side, oils are subject to constant improvements, particularly concerning the additives allowing a better resistance towards oxydation and fuel economy. Refer to the expertise of the local Nanni Industries representative regarding the oil that best suits your engine.
This can lead to the invalidation of Nanni’s Water used in the cooling system should meet the warranty for faults and damage caused by the use of following minimum specifications for quality : inappropriate coolant.

Extend exhaust line, excessive cranking could cause seawater this period to 2–4 minutes at freezing or sub-zero to enter the cylinders and damage the engine.
Any mechanical power taken from the engine from a PTO reduces the power delivered to the propeller. The use of a PTO should always be studied and approved by the R&D department of Nanni Industries S.A.S France. Contact your Nanni dealer for more informations.
Check the instruments and warning lamps after starting, neutral position. and regularly when cruising. Consult the boat builder or your Nanni dealer if you are not sure about the operation of the remote control.
STARTING & RUNNING CRUISING SPEED MANOEUVRING A recommended engine speed is given in the TECHNICAL DATA section to help you to set your cruising speed. WARNING ! NOTE ! Shifting at high speed can damage both the engine and the transmission and be dangerous for passengers. Always consider sailing conditions and load of the boat to set the cruising speed.
STARTING & RUNNING ENGINE AND SAILING CAUTION ! When under sail, it is possible to limit the resistance produced by the propeller of the engine. Sailing with the engine stopped and with the lever in neutral must not exceed 6 hours in a row. The propeller can drive the rotation of the shaft and damage the transmission.
STARTING & RUNNING AFTER RUNNING AFTER STOPPING THE ENGINE STOPPING THE ENGINE CAUTION ! Even after the engine has stopped, some components CAUTION ! and fluids will remain hot and under pressure for several minutes. As far as possible, limit works on the engine Never stop the engine by using the main switch.
STARTING & RUNNING ANCHORING If the boat is not going to be used for some time but is being left in the water, the engine must be run to operating temperature at least once every 2 weeks. This prevents corrosion in the engine. When the boat is at anchor or in port for an extended period of time, vegetation may develop on the hull, the keel, the drive, the rudder, the propeller, etc.

7. At this stage, the raw circuit is alleged to be cleaned up. If deposits and salt crystals are still present, con- sult your Nanni representative. Do not add up clean- ers additives of your own taste, as metal parts are prone to fast corrosion if harshly cleaned.
To charge two independent batteries with a single alternator, an isolator is available as an option on most engines. Contact an authorized Nanni representative. WIRES AND CONNECTORS KEEP CLEAN THE BATTERY Check that electrical wires and connectors are dry and in good condition.
MAINTENANCE CONNECT THE CABLES ELECTROLYTE LEVEL CHECK 1. Always connect first the positive lead (+) to the positive terminal (+) of the battery As a conservative rule, electrolyte level must always be 2. And then the negative (-). above the top of the lead plates (+/-1 cm - slighlty less than half of an inch).
MAINTENANCE ALTERNATOR BELT If not within specification, loosen the alternator (in grey on picture) and relocate it properly to adjust. The engine alternator is driven by a belt through pulleys. These components must be in good order at all times in view for the alternator to provide electricity, among others, to the engine, to the battery, to the engine control panel.
If the fault is not resolved quickly, contact your nearest Nanni representative for repair. If you are at open sea, try to locate the fault and to repair Fuse and relay box by yourself.
