Malibu Boats M235 2019, Owner'S Manual

Page: 199 / 238

With the standard, manual system, there is a junction that does
require occasional lubrication with marine-grade grease. This junction
is accessed from the starboard side engine close-out in Wakesetters.
In the Response and TXi, only the manual steering is offered.
(Never ignore any steering issues, regardless of timing for the
annual maintenance check-up.)
Shift and Throttle System
As with the steering, never ignore suspicious issues with the
shifter/throttle. Anytime the lever does not move smoothly or the boat
does not shift/accelerate/decelerate with ease and smoothness, it is
a matter to be resolved by an authorized Malibu dealer.
Do not wait
for the annual maintenance period to verify safe operations.
Battery
Your authorized Malibu dealer can check to see that the
battery(ies) appear to be holding charge properly. Unless a battery has
fully expended its life cycle, it’s impossible to guarantee that the battery
will continue to serve, but experience helps the dealer to anticipate
whether there is still service to be expected from the battery.
When it is necessary to replace a battery, be certain to select a
marine-grade battery with at least eight hundred (800) cold cranking
amps (cca) at zero degrees (0
o
) Fahrenheit. Spiral cell batteries are
superior in holding charges and extending the period of available
usage.
Considerably more information about batteries is available in the
Dashes and Video Screen section of this Owner’s Manual.
Refer to your battery supplier for advice regarding long-
term storage and/or winterization. If your battery manufacturer
recommends removing the battery(ies) from the boat, verify whether
the manufacturer requires that the battery(ies) is/are fully charged.
Follow common sense
safety instructions regarding
the removal or installation
of batteries. Due to
potentially explosive fumes and corrosive battery acid,
failure to wear protective items and follow instructions
correctly could result in serious injury or even death.
• Because of corrosive and explosive qualities in battery acid and
fumes, put on safety glasses and mechanic-type safety gloves.
• Determine the size socket required to disconnect the battery
cables and bracket nuts. Extensions may be required.
• ALWAYS DISCONNECT THE NEGATIVE (-) CABLE FIRST.
• Ensure that the negative cable will not come in contact with the
positive cable during the rest of the procedure.
• Disconnect the positive (+) cable, TAKING CARE TO AVOID ANY
CONTACT BETWEEN THE POSITIVE BATTERY CABLE AND
ANY METAL.
There may be residual charge still in the electrical
system, which could result in a serious electrical shock or burns.
• With the battery cables disconnected and out of the way, remove
the bracket nuts holding the battery in place.
• Batteries should always be stored in a cool, dry location.
Manufacturers generally prefer batteries be stored on shelving
above floor level.
• Using an old toothbrush or similar bristled brush, and a mix
of baking soda and water, clean off the battery terminals and
cable ends, if they show any signs of corrosion. A small amount,
especially as batteries age, is not uncommon, but excessive
corrosion could be sign of future service interruptions, and it
should be brought to the attention of your authorized Malibu
dealer. Allow the terminals and cable ends to air dry.
• Clean the battery lugs with a wire brush.
Following the storage period, reverse the above steps to reinstall
the battery(ies).
Pumps
The authorized Malibu dealer can inspect and repair/replace ballast
and bilge pumps that are not functioning properly. This is both a safety
matter and adds to the life of the boat’s systems. All pumps will lose
functionality over time as the internal components are designed to
be self-sacrificing during use, rather than allowing debris to foul and
damage more expensive and complex components of these systems.
Insist upon pump evaluations during annual maintenance.
Coolant System
There are two (2) elements to the coolant system in Malibu boats:
the closed-cooling system and the raw water intake system. Both
require attention on a regular basis. Depending on the body of water,
attention may need to be frequent.
Any time the engine
temperature raises above
normal operating levels
(approximately 155-175 degrees) operators must
determine the source of the overheating and address the
issue. Often, it may be caused by debris in the sea strainer
(raw water intake). If cleaning the sea strainer does not
result in lower operating engine temperature, have the
boat towed to shore and take it to an authorized Malibu
dealer for analysis. Failure to immediately address
overheating issues can void the warranty.
