For Extended Storage and Winterization
There are multiple steps required to prevent damage to the boat
when it will not be used for an extended period, especially during
colder weather months. Malibu recommends having an authorized
Malibu dealer execute the storage/winterization process, followed by
recommissioning when ready to begin use.
For Malibu Monsoon engines, fill the fuel tank full. You will need
to use a STA-BIL
®
gasoline stabilizer.
Reminder: Stabilizers work
in fresh gasoline only.
Adding a stabilizer after storage during the
recommissioning period will not eliminate the gumming or water-
separation that may have occurred.
Stabilizers are preventatives,
not curatives.
All gasoline stabilizers have a limited life. Be sure
to review the requirements as stated on STA-BIL
®
packaging or seek assistance from your authorized
Malibu dealer in determining how long and under
what conditions you can reasonably expect the STA-
BIL
®
to serve as designed.
Gasoline should never be stored for a period to
exceed six (6) months.
If it is necessary to remove
gasoline from the tank and dispose of it, be certain
to do so in compliance with local, state, and federal environmental
laws/rules/ordinances.
All water than can be removed from the boat must be. This
includes water in the engine, ballast, and bilge areas. Water that is
not removed may freeze. Expansion and contraction that takes place
as a result will damage affected areas of the boat. Such damage is
not covered under warranty. This damage can be extensive and very
expensive to repair.
There are four (4) drain plugs on the Malibu Monsoon engine (see
photo), in addition to the T-handle in the bilge compartment and the
transom drain plug.
ALL PLUGS MUST BE REMOVED, AND ALL WATER
DRAINED PRIOR TO STORAGE TO PREVENT POTENTIAL FREEZING AND
DAMAGE TO THE ENGINE AND BOAT.
The circulating hose on the starboard side and aft of the engine
under the heat exchanger may or may not have a plug. If equipped
with a plug simply remove it. If not, you must do the following: Loosen
the clamps holding the hose in place and allow it to drop down to
drain any residual water in the system. This is the lowest area of
the circulating water system, and gravity should allow any water to
drain that was not previously drained.
NOTE
: When reconnecting this hose as the boat is recommissioned
prior to operation, be sure to tighten the clamps holding this hose but
DO NOT OVERTIGHTEN
. The clamps should be tight enough to prevent
leaking, but over tightening them will accelerate wear and tear on
the hose and could eventually cause failure that is not covered under
warranty.
All drain plugs in the boat, regardless
of the engine manufacturer, must be
removed and all water drained prior to
storage, particularly during winter months, to avoid potential
freezing and damage to the engine and the boat. Such damage is
not covered under warranty.
The electric valves (not visible) need to be opened to let water
escape to avoid freezing that could crack the valves. To complete:
• With the boat out of the water, turn the ignition ON to control the
process from the 12” display.
• On the Ballast page, press “FILL ALL.”
• Allow the system to run for thirty (30) seconds. No longer, no
shorter.
• Click “STOP ALL” at the conclusion of the thirty (30) seconds.
• The process allows any remaining water to be expunged.
If the batteries are removed for storage, they should be fully
charged prior to removal. Batteries should be stored in cool (but
not cold), dry locations. Never store batteries near heat devices or
anything that causes a spark or electrical charge. Fully recharge the
battery prior to reinstallation.
NOTE: If the battery is removed from the boat, the automatic bilge
system will not operate, and water will not be discharged from the
bilge. Therefore, boats that are stored in water must not have the
batteries removed.
Additional Steps to Complete for Storage:
• Drain any residual water from the plumbing.
• Thoroughly wash and clean the boat, inside and out, as instructed
in the
Ongoing Care section of this manual.
• Leave the bow slightly elevated so that any further draining of
water from the bilge system will run out and not accumulate
inside the bilge system.
• Remove the drain plug(s) and place them in see-through plastic
sacks or containers. Place them inside the boat so that they will
be immediately locatable for recommission.
• Using low-tack tape, tape around the exhaust flap so that vermin
cannot chew their way into and nest inside the exhaust system.
• Apply wax to the entire exterior surface to protect the hull and
deck finishes, particularly from dampness and condensation that
may occur.
• Remove the propeller and store in a safe place.
• Remove the seat cushions and store in a cool, dry location. Open
Always pay attention to whether all
water inlets and drains are open or
closed. Failure to follow directions
can result in too much water (which could result in sinking of
the boat) or too little water (which could result in insufficient
cooling, which could damage the drive train and is not covered
under warranty)!
Care and Maintenance—149
• Start the engine and the pump will automatically pump the
coolant from the bucket into the engine and manifolds.
DO NOT
EXCEED 1100 RPM.
• When the bucket is empty,
IMMEDIATELY
shut down the engine.
The engine drain plugs are located: 1. The V-drive. 2. The bank 1 manifold.
3. Under the heat exchanger. 4. The bank 2 manifold.
