SERVICE MANUAL NUMBER 23
MAINTENANCE
Maintenance Schedules
Maintenance Intervals
Maintenance intervals and the tasks to be performed, as shown in this current schedule, or
as found in a previously printed schedules, are generally based on an average boating
application and environment. However, individual operating habits and personal mainte-
nance preferences can have an impact on the suggested intervals. 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 prevent injury to yourself and damage to electrical system should a wire be
accidentally shorted.
