CHECK THE PROPELLER SHAFT COUPLING ALIGN-
MENT
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 propeller shaft coupling.
Step 3: Remove the coupling bolts and slide the coupling apart only slightly so that
the pilot flange on the propeller shaft side is still seated in the pilot bore of the trans-
mission side.
Step 4: Using a feeler gauge, measure the gap between the coupling halves at
four places. Rotate the coupling flanges together one complete revolution, stopping
every 90
o
to check clearance with the feeler gauge.
Step 5: Alignment is satisifactory when the flanges are parallel within 0.003 inch.
Step 6: If the alignment is not satisfactory, an adjustment must be made. Special tools and procedures are required for
proper adjustment and should be made only by a trained technician. See your MasterCraft dealer.
Step 7: If alignment is satisfactory, re-install the flange bolts and tighten securely.
Step 8: Water test to ensure that there is no vibration. If a vibration is noticeable, see your MasterCraft dealer immediately.
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
lever is in neutral.
Step 2: Inspect the exhaust flap hinge for signs of deterioration. Replace the flap if necessary.
LUBRICATE THE STEERING SYSTEM
Because this process should be completed while all
moving components of the drive train are NOT in
motion, we recommend you do this 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.
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.
