150 Care & Maintenance | 2021 OWNER’S MANUAL
• Connect a gardening-type hose as shown in the
accompanying photo to the flush kit system at the
connector and turn on the fresh water at the source.
• With the boat shifter in neutral, start the engine and allow
it to idle. During the entire process, DO NOT EXCEED
1100 RPM on the engine. The freshwater hose cannot
provide sufficient water supply to adequately cool the
engine at higher RPMs. Also, never take the boat out of
neutral gear.
• After approximately two-to-three (2-3) minutes of
flushing, shut off the engine.
• Turn off the freshwater supply.
• Disconnect the hose and reinstall the cap on the flush kit
connector.
Winterizing Procedure
After flushing the
engine, remove the
T-handle drain plug in
the bilge compartment,
and the engine drain
plugs located on the
V-drive under the
coupler, bottom of the
heat exchanger, and
both manifolds.
All drain plugs should
be placed in a plastic
bag and stored in a
visible location so when
recommissioning the
boat, the plugs will not
be overlooked.
• After flushing with fresh water, open all drain cocks.
Depending upon the model, there may be several.
• When the water has fully drained, close the drain cocks
and tape shut the water inlet on the bottom of the boat.
Use low-tack type of tape to avoid damaging the finished
on the inlet and surrounding metal and gel coat. The
water pickup does NOT need to be taped.
• With the boat shifter in neutral, start the engine and allow
it to idle. During the entire process, DO NOT EXCEED
1100 RPM on the engine. The freshwater hose cannot
provide sufficient wear supply to adequately cool the
engine at higher RPMs. Also, never take the boat out of
neutral gear.
• Run until there is no longer water coming out. DO NOT
RUN THE ENGINE FOR MORE THAN 30 SECOND ! This
procedure allows any remaining water in the system to be
forced out.
• Remove the tape from the raw water intake, and the
garden hose from the valve.
Winterizing with the Boat in Water
• After the flushing process is complete, remove the
adapter from the flush pump cap strap and insert the
adapter into the flush pump valve.
• Using a piece of gardening type hose, place the male
end of the hose into the flush kit fitting and place the
other end into a container of the mare-grade, 50/50
mix of distilled water and propylene glycol coolant, if
not using a pre-mix of the same.
• Open all petcocks and drain the engine block and
water-cooled manifolds. If the petcocks are plugged,
carefully unclog the openings. When all the water has
drained out, close all petcocks, and replace any plugs
that were removed.
• 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.
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 ever 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 three (3) drain plugs on the Malibu Monsoon engine,
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 engine drain plugs are located:
NOTICE
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).
