Section 5 - Maintenance
90-866938081 MAY 2009 Page 81
It is recommended you have the Cummins MerCruiser Diesel Authorized Repair Facility
do periodic maintenance checks on your power package. Have them winterize it in the fall
and service it before the boating season. This will reduce the possibility of any problems
occurring during your boating season when you want trouble‑free boating pleasure.
Inspection
Inspect your power package at regular intervals to help maintain top operating performance
and avoid potential problems before they occur. Check the entire power package
carefully, including all accessible engine and drive parts. For engine inspection
information, refer to the appropriate Cummins Marine Engine Operation and
Maintenance Manual .
1. Check for loose, damaged, or missing parts, hoses, and clamps. Tighten or replace as
necessary.
2. Check electrical connections and leads for damage.
3. Remove and inspect the propellers. If nicked, bent, or cracked, contact your Cummins
MerCruiser Diesel Authorized Repair Facility.
4. Repair nicks and corrosion damage on the power package exterior finish. Contact your
Cummins MerCruiser Diesel Authorized Repair Facility.
While inspecting the power package and drive, certain components can be damaged by
the weight of an individual and must not be used as a step. Decals on top of the drive
components indicate where no step is allowed. Do not step on components with a decal.

The Zeus drive cover, if equipped, protects and separates some components after the drive
is installed. The drive cover provides added protection against damage to the hoses and
other components as a result of mechanical hose abrasion during operation or damage to
the hoses, such as being stepped on during service or maintenance. If equipped, keep the
drive cover installed except when removed for service.
