Maintenance Schedule
Maintenance Intervals
Maintenance intervals and the tasks to be performed, as shown in this current schedule, or as found in a pre-
viously printed schedules, are generally based on an average boating application and environment. However,
individual operating habits and personal maintenance preferences can have an impact on the suggested inter-
vals. In consideration of these factors, MerCruiser has adjusted some maintenance intervals and corresponding
tasks to be performed. In some cases, this may allow for more individual tasks to be performed in a single visit
to the serving dealer, rather than multiple visits. Therefore, it is very important that the boat owner and servicing
dealer discuss the current Maintenance Schedule and develop appropriate maintenance intervals to coincide
with the individual operating habits, environment, and maintenance requirements.
Always disconnect battery cables from battery BEFORE working around electrical systems components to pre-
vent injury to yourself and damage to electrical system should a wire be accidentally shorted.
