nical training to best meet your service needs.

Annually

(Every One Hundred [100] Hours)

MasterCraft recommends that your annual—or one hundred (100) hour—maintenance require-

ments be performed by an authorized MasterCraft dealer. The staff there has the proper equipment and

technical training to best meet your service needs.

Annual Maintenance

Some boat owners choose to personally execute some maintenance procedures on their boats. Mas-

terCraft has provided information on several procedures. For safety reasons, a few must be performed by
authorized MasterCraft service technicians only, such as anything involving checks and repairs on the fuel
line, which is under pressure.

These matters must be addressed on a regular basis, at one hundred (100) hours or annually, whichever

comes first, and these procedures are in addition to seasonal preparation and winterization (see Storage and
Winterization section for additional details). All of these issues are extremely important to continued boating
pleasure, as well as long life for the boat, and the critical matter of safety.

Even if the annual maintenance work is completed by an authorized MasterCraft service technician,

boat owners and operators should still review this section and ensure that they have some understanding
of what is necessary to keep the boat in top condition.

Check the Engine Mounts

2011 Owners Manual...Scheduled Maintenance...Page 17-6

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/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 adjustment lock-nuts. Tighten any
loose hardware securely.

Check the Propeller Shaft Coupling Alignment

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 transmission 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

to check clear-

ance with the feeler gauge.

Step 5:

Alignment is satisfactory 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 proce-
dures 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.
