5.1 List of Periodic Inspections
'Daily and periodic inspection are important to keep the engine in its best condition. The following
is a summary of inspection and servicing items by inspection interval. Periodic inspection intervals
vary depending on the uses, loads, fuels and lube oils used and handling conditions, and are hard
to establish definitively. The following should be treated only as a general standard. Schedule
your own periodic inspection plan according to the operational conditions of your engine and
inspect every item. Neglecting periodic inspection leads to engine troubles and shortens the life of
the engine. Refer to the various accompanying operation manuals for periodic inspection and
maintenance for marine drive and remote control system.
