SERVICE MANUAL NUMBER 28

Maintenance Schedules
Maintenance Intervals
Maintenance intervals and tasks, as shown in this schedule, or as found in previously
printed schedules, are based on an average boating application and environment.
However, individual operating habits and personal maintenance preferences can have an
impact on the suggested intervals. In consideration of these factors, Mercury MerCruiser
has adjusted some maintenance intervals and corresponding tasks to be performed. In
some cases, this may allow for more tasks to be performed in a single visit to the servicing
dealer, rather than multiple visits. Therefore, the boat owner and servicing dealer must
discuss the current Maintenance Schedule and develop appropriate maintenance intervals
to coincide with the individual operating habits, environment and maintenance
requirements.
CAUTION
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.
