throttle/shift control lever is in neutral. The engine
must be cool.
e engine box serves as a machinery guard. e en-
gine must be OFF whenever the box is open. Clothing
or body parts can get caught in moving parts, causing
death or serious injury. Keep away from moving parts.
Step 2: Open the engine compartment and visually check the ex-
haust system from the engine to the transom for any obvi-
ous damage to exhaust lines or the mufer.
Step 3: If leakage is apparent, tighten the hose clamps, being careful
to avoid crimping the hose. If the leakage is signicant, or is
occurring at a location other than the joints (such as a split
in a hose), see your authorized MasterCraft dealer’s service
department for parts and service. This is important!
Ex-
haust fumes can cause illness or impairment, includ-
ing carbon monoxide poisoning. Equally important
to consider, leakage can lead to a build-up of poten-
tially explosive fumes within the engine compart-
ment. DO NOT IGNORE OR OVERLOOK THIS
INSPECTION! REPAIR AS NECESSARY!
After Each Use
General Cleaning and Storage
Refer to the Corrosion Prevention and Cleaning the Boat sections of
this Owner’s Manual. After each outing, the boat should receive a gen-
eral cleaning and drying prior to being stored. Even if the boat is kept
in a slip, owners/operators should wipe down the interior and should
periodically remove the boat from the water for a general cleaning.
Inspections
As noted in the Before Each Use section, some functions there
need to be performed following use of the boat, such as checking the
intake strainer or seacock strainer if evidence has shown that debris
collects during the outing. Wet debris is often easier to remove.
Quarterly
(Every Fifty [50] Hours)
MasterCraftrecommendsthatyourquarterly—orfty(50)

rized MasterCraft dealer. The staff there has the proper equip-
ment and technical training to best meet your service needs.
Lubricate the
Engine Starter Gear
and Shaft
Some engine parts become
very hot during operation.
This maintenance 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 the engine safety starting switch
is disconnected.
Be certain that the throttle/shift con-
trol lever is in neutral. The engine must be cool.
Step 2: Disconnect the positive (+) battery terminal.
Step 3: Open the engine cover and locate the starter on the lower
starboard side of the engine.
Step 4: Disconnect the starter and carefully remove it.
Step 5: Lubricate the starter bendix with a light coating of water-
proof grease or white lithium grease.
Step 6: Return the starter to the engine and reconnect. After clos-
ing the engine compartment, reconnect the positive (+) bat-
tery terminal.
MasterCraft recommends that your quarterly—
or fty (50) hour—maintenance requirements
be performed by an authorized MasterCraft
dealer. The staff there has the proper equip-
ment and technical training to best meet your
service needs.

ment and technical training to best meet your service needs.
Annual Maintenance
Some boat owners choose to personally execute some main-
tenance procedures on their boats. MasterCraft has provided in
-
formation 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 hun-
dred (100) hours or annually, whichever comes rst, and these proce-
dures 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 autho-
rized MasterCraft service technician, boat owners and operators
should still review this section and ensure that they have some un-
derstanding of what is necessary to keep the boat in top condition.
MasterCraft recommends that your annual—or
one hundred (100) hour—maintenance re
-
quirements be performed by an authorized
MasterCraft dealer. The staff there has the
proper equipment and technical training to
best meet your service needs.
