Check the
Engine Mounts
Some engine parts become very hot during operation.
is inspection must be completed while the engine is
cool to prevent burns to your skin. Perform this task
before starting the boat.
Step 1: Ensure the engine is OFF and disconnect the engine safety
starting switch. Be sure that the throttle/shift control
lever is in neutral. The engine must be cool.
Step 2: Open the engine box and locate the four (4) motor
mounts.
Step 3: Check the tightness of the mounting hardware and adjust-
ment lock-nuts. Tighten any loose hardware securely.
Check the
Propeller Shaft
Coupling Alignment
Later-model MasterCraft boats
are equipped with a dripless
propeller shaft log. If it is show-
ing signs of drips, it must be cor-
rected by an authorized Master
-
Craft dealer’s service technician.
Inspect the
Exhaust Flaps
for Damage
Step 1: Ensure the engine is OFF
and disconnect the engine safety
starting switch.
Be sure that
the throttle/shift control le-
ver is in neutral.
Step 2: Inspect the exhaust ap
hinge for signs of deterioration.
Replace the ap if necessary.
Lubricate the Steering
System
Because this process should be
completed while all movable com-
ponents of the drive train are NOT
in motion, MasterCraft recom-
mends this be done while the boat
is out of the water.
Step 1: Ensure the engine is OFF and disconnect the engine safety
starting switch. Be sure that the throttle/shift control lever
is in neutral. The engine must be cool.
Step 2: Remove the access panel in the rear trunk compartment
in direct drive boats. In V-drive
engines the steering is located
in the engine compartment, be-
neath the engine.
Step 3: Turn the steering
wheel so that the maximum
amount of steering cable is
seen.
Step 4: Use solvent to clean
old lubricant from the cable end,
pivot and rudder shaft.
Step 5: Spread a generous amount of white lithium grease over the
cable end. Work the steering wheel back and forth and re-
apply grease if necessary.
Step 6: Using the exible end of a grease gun, give two (2) full shots
of white lithium grease to the two (2) grease ttings: one
on the rudder shaft, and one on the pivot. Clean up any old
grease purged from the areas.
Step 7: Rotate the steering wheel back and forth several times to
work the lubricant in.
Step 8: Re-install the access panel.
Lubricate the Shift
and rottle System
Because this process should be
completed while all movable com-
ponents of the drive train are NOT
in motion, MasterCraft recom-
mends this be done while the boat
is out of the water.
Step 1: Ensure the engine is OFF
and disconnect the engine safety starting switch. Be sure
that the throttle/shift control lever is in neutral. The
engine must be cool.
Step 2: Open the engine box and locate the shift and throttle cable
ends.
Step 3: Shift to full-throttle-forward.
Step 4: Lubricate the cable ends and connections with a coating of
waterproof marine multi-purpose grease.
Step 5: Lubricate the pivots and linkages with a light grease.
Step 6: Shift the control lever from full-throttle-forward to full-throt-
tle-reverse several times to work the lubricant in.
Check the Ballast
Pump Impeller
This applies only to boats equipped
with some type of ballast system.
The number of ballast pumps
varies from system to system. Au-
thorized MasterCraft dealers can
provide guidance to locate any and
all pumps.
Step 1: Remove two (2) of the cover screws and retain the screws
for the reinstallation process. Swing the cover out of the
way to allow access to the impeller location.
Step 2: Using needle-nose pliers, pull the old impeller out of the
casing.
Step 3: Install a new impeller. (It is intentionally larger than the case.
While gently squeezing it in, ensure that the paddle wheels
angle in the same direction—counterclockwise—all the way
around.)
