Warranty - Malibu Boats Wakesetter 20VTX 2019 Owner's Manual

• 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 pet cocks
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.
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)!

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.
It is important to ensure that all required drivetrain precautions
are taken; for these, see the Malibu Monsoon by PEG engine
owner's manual for boats equipped with those engines.
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.

Always pay attention to
whether all water inlets and
drains are open or closed.
https://www.boat-manuals.com/
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 drain plugs on the Malibu Monsoon engine,
in addition to the T-handle in the bilge compartment and the
transom drain plug. ALL SIX 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:
1. On the side of a circulating hoseon the starboard side and aft
of the engine under the heat exchanger.
2. Under the shaft coupler on the front of the v-drive.
