Some engine parts become very hot during operation. This
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/shi
control lever is in neutral. e 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
adjustment lock-nuts. Tighten any loose hardware
securely.
Check the Propeller Shaft
Coupling Alignment
Later-model MasterCra boats are equipped with a dripless
propeller sha log. If it is showing signs of drips, it must be cor-
rected by an authorized MasterCra 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/shi
control lever is in neutral.
Step 2: Inspect the exhaust ap hinge for signs of deteriora-
tion. 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, MasterCra 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/shi
control lever is in neutral. e engine must be cool.
Step 2: Remove the access panel in the rear trunk compart-
ment in direct drive boats. In V-drive engines the steer-
ing is located in the engine compartment, beneath 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 sha.
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 sha, 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.
