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.
(Pages 17-2, 17-6)
Towers should never have a total aggregate weight of accessories
exceeding 85 lbs. (U.S.) total. Excessive weight can cause tower
failure and the collapse of a tower or the disconnection of the
tower from the deck, which could result in serious bodily injury or
damage to the boat that is not covered by warranty.
(Page 1-7)
Prior to operation of the boat, verify that the mirror hardware is
secure. Failure to do so may result in the mirror detaching from
the windshield extrusion. The mirror could hit the operator or a
passenger, resulting in injury.
(Page 6-5)
Convertible seat backs should always be in the forward-facing po-
sition when the boat is underway. Anyone seated facing aft could
become dislodged when the boat is underway, which could result
in sliding off the seating and making contact with the transom or
swim platform. Jump seats should be secured against the deck with
a lock pin accessible under the observer seat to avoid dislodging passengers while the boat is underway. Con-
vertible seat backing should always be secured prior to use. Care should be taken to avoid pinching fingers or
other skin when sliding the backing.
(Page 6-8)
When boating, avoid using the windshield as an aid for balance or getting out of a seat. This causes undue stress
to the window frame and could damage it, which may not be covered under warranty.
(Page 8-1)
To ensure proper break-in and lubrication, boat owners should not remove the factory break-in oil until
after the initial ten (10) hours of operation. At that time, an oil change should be performed on the Indmar
engines by an authorized MasterCraft service technician at an authorized MasterCraft dealer.
(Page 9-1)
DO NOT use the ski pylon or any portion of any tower for lifting. They are NOT designed to be used as a cen-
tral lifting point. Also, DO NOT use the stern ski tow as a lifting ring. The deck may be damaged. See the
Stor-
age Cradle
sub-section of this section. Also never lift a boat with water in the bilge or containing a water-filled
device such as a ballast system or sack. The extra stress will put an excessive load on the hull and lifting equip-
ment that may seriously damage the boat. Such damage may not be covered by the warranty.
(Page 12-1)
Continued operation after the warning light has illuminated may cause severe engine damage. This will void
your warranty.
(Page 10-3)
Because of the complexity of preparing a boat for proper winter storage, as well as the possibility of extreme
damage to the drive train if a preparation error was made during winterization, MasterCraft recommends
scheduling an appointment with an authorized MasterCraft dealer’s service department to permit a techni-
cian to perform all winterization procedures.
(Page 18-1)
Add-on equipment may adversely affect the alternator output or overload the electrical system. Such damage
may not be covered by the warranty.
(Page 17-2)
Failure to follow the engine oil recommendations listed in the engine manual can cause additional engine
wear and increase the possibility of engine component failure. Damage to the engine due to incorrect oil us-
age can be costly to repair, and is not covered by the warranty!
(Page 9-1)
Do not operate the starter motor continuously for more than fifteen (15) seconds without at least two (2)
minutes for a “cool-down” period. Failure to do so may cause the starter to overheat, resulting in damage.
Failure to release the ignition key after the engine has started may cause damage to the starter motor and
drive.
(Page 10-1)
Allowing the fuel level in the fuel tank to fall below one-quarter of a tank full may affect the reliability of the fuel
pump or result in damage to the fuel pump, which is not covered under warranty.
