Check the Propeller Shaf Coupling
Alignment
This function is critical to avoiding unnecessary wear and potential
damage to the engine as well as the propeller and propeller shaft.
Because it is a complex and exacting part of maintenance, this
should be performed only by your authorized MasterCraft dealer as
part of your annual maintenance.
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 rubber exhaust flap for signs of deterioration. Take the boat
to an authorized MasterCraft dealer to replace the flap if necessary.
Lubricate Steering System
For cable systems only (both standard steering and DockStar
Handling System); hydraulic steering maintenance must be
completed by an authorized MasterCraft dealer only. Because this
process should be completed while all movable components of the
drive train are NOT in motion, MasterCraft recommends lubrication
be done while the boat is out of the water. The process below is
for all MasterCraft boat models. Additional steps listed after are
required for ProStar rudders.
Check the Engine Mounts
Some engine parts become very hot during operation. This inspec-
tion 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. Securely tighten any loose hardware.
