Malibu Boats RESPONSE TXi 2021, Owner'S Manual

2021 OWNER’S MANUAL | Engines & Drive Trains 91
The boat is also equipped with a natural air intake that forces
air through a ventilation system on the deck of the boat. This
channels air from the bilge to the transom vent.
With proper maintenance, which is the responsibility of
the boat owner and/or operator, the ventilation system works
efficiently and protects the people onboard from dangerous
fumes. Follow the maintenance requirements as indicated in the
Care and Maintenance section of this manual.
Never operate the boat if you or anyone on board suspects
that the exhaust or fuel system is not performing as
designed.
Break-in Period – All Boats
Breaking in marine engines is a different process from land-
based vehicles. The first 10 hours of operation for your Malibu
engine is critical for long life and enjoyable operation. When
done properly, the break-in period will ensure peak performance.
The first hours of the boat operation have critical
requirements for engine break-in. Pay close attention to the
screens and monitor the readings. Pay particular attention to the
oil pressure and engine temperature information as these are the
earliest warnings when something is going wrong with the drive
train. Alarms will sound if serious problems are encountered.
Also, check carefully for leaks. The break-in period is the
most likely time for leaks to appear, whether fuel, oil, water, or
exhaust. Verify that fluid levels are at the required levels. Listen
for abnormal noises and pay attention to vibrations.
Any part of the operation that seems to be different from
expectations should be checked with your authorized Malibu
dealer, especially during this break-in period.
Break-in Procedure
Malibu boats undergo a general pretest run at the factory
before shipping. The customer-based break-in period takes
place for the next 10 hours of operation. (The video screen
includes an hourmeter function that allows consumers to keep
track of the number of hours the boat has been in operation.
See Dashes and Video Screens in this manual for details.)
The break-in procedures, which should be followed for
the first 10 hours of operation as measured by the integrated
hourmeter, allow the engine and transmission components
to properly seat and function in the usage thereafter. These
procedures are as follows:
• Always allow the engine to warm up after it is started. The
length of time varies depending upon conditions, but it is
especially critical when operating in colder weather. Oil
viscosity thickens at these times. Failure to allow it to
warm up can cause severe damage to the engine, which is
not covered under warranty. This is time in addition to
the 4 minutes venting the engine compartment. Engine
temperature is available on the video screen. Always verify
that the engine feedback information on the video screen is
within acceptable limits and no alarms show or sound before
leaving the dock. Often, symptoms of potentially stranding
issues will be noticeable at the beginning of the outing.
• Vary engine speed, but DO NOT EXCEED 3500 RPM with
light load for the first hour.
• After the first hour, higher RPMs are allowable up to, but
NOT EXCEEDING, 5000 RPM, but operators must avoid
operating at one continuous speed (RPM). Varying
the speed is important. NEVER RUN AT WIDE OPEN
THROTTLE (WOT) DURING THE BREAK-IN PERIOD!
• Never operate at idle speed for extended periods during
the break-in period. Occasionally, return the shifter/throttle
to neutral for a cool-down period, but do not operate at
idle speed for extended periods. It is better to turn Off the
engine than to idle indefinitely.
• Operate above 1500 RPM carefully. If the body of water is
choppy or if there are other challenges present, operate at
lower RPM. Boating conditions can add strain to drive train
operation.
• Always shift and accelerate smoothly during break-in. Avoid
rapid operational changes. Plane the boat quickly as lower
speeds can put more strain on the engine.
• Do not do your first oil change before 10 hours or later than
15 hours.
Do not allow the ventilation intake to be covered up by towels, swim
paraphernalia, or any other item that potentially restricts the inflow of
air for the proper ventilation of the blower system. Such restrictions
can result in the accumulation of toxic fumes, which can lead to an
explosion under certain circumstances. All types of restricted ventilation
are dangerous and can lead to serious injury or death!
DANGER
!
The State of California has determined that the engine exhaust
contains chemicals that have been known by the state to cause birth
defects, cancer, or other reproductive harm.
! WARNING
Failure to have the initial, 10-hour oil change performed by an
authorized Malibu dealer may result in the voiding of the engine
portion of the warranty if it is determined that engine issues could
have been analyzed and/or prevented through the dealer’s inspection
at that time.
