Zeus Propellers
The Cummins Zeus propulsion package features stain-
less steel propellers matched to ensure the best all-around
performance. Currently the 53 SC is outfi tted with a M-11
propeller set.
It is recommended to carry an extra set of propellers and
hardware since the vessel operator on extended cruises
could fi nd replacement parts diffi cult to obtain in cer-
tain locals. Parts can be ordered fom the closest Cummins
MerCruiser diesel repair facility.
Note that at times propellers can be repaired.
WARNING
!
AVOID SERIOUS INJURY OR DEATH!
NEVER OPERATE THE VESSEL OUT OF THE
WATER WITH PROPELLERS INSTALLED!
BEFORE REMOVING OR INSTALLING
PROPELLERS. REMOVE THE KEY FROM THE
SWITCH, PLACE THE DRIVE IN NEUTRAL,
AND ENGAGE THE E-STOP HELM SWITCH TO
PREVENT THE ENGINE FROM STARTING!
NOTICE
NEVER CONTINUOUSLY RUN WITH A
DAMAGED PROPELLER SINCE
TRANSMISSION AND/OR ENGINE HARM
COULD RESULT.
Engine & Controls
When installing propellers lube the propeller shaft with
2-4-C Mercury lubricant. Make sure all parts are installed
in the correct order.
Torque the front propeller nut to 100 ft. lbs.

Zeus Propeller Removal
Read and understand the warning label on this page
before removing propellers!
In most cases the vessel will need to be hoisted to re-
move damaged propellers or components. At other times
a diver may need to be hired to change out damaged pro-
pellers.
1. Place an appropriately sized block of wood between
the rear propeller and the trim tab.
(Note it is recommended that heavy gloves be worn when
handling propellers due to their sharp edges).
2. Turn the rear propeller nut counter-clockwise to re-
move the nut.
3. Remove the propeller and thrust hub from the propel-
ler shaft.
4. Using the propeller nut tool (Mercruy # 91-805457T1)
turn the front propeller nut counter-clockwise and re-
move the nut.
