Before Starting The Engine - Malibu Boats Wakesetter 20VTX 2019 Owner's Manual

Malibu has determined that the use of Corrosion Block is
necessary to ensure long life for metal components. The use of
Corrosion Block, available at www.corrosionblock.com, as directed
on the bottle or can is required to keep the warranty in force.
Corrosion Block comes in aerosol spray, liquid that can be placed in
your own spray bottle, or as a grease.
Avoid getting Corrosion Block on other, non-metal surfaces,
particularly vinyl seats or soft-grip flooring. If this occurs, clean
immediately as directed by the product's directions to avoid
stains that are also not covered under warranty.

Before Starting the Engine

Check Coolant Level
Be certain the emergency safety stop switch is disconnected and
the shifter/throttle is in neutral. Open the engine compartment hatch
and locate the coolant reservoir. The reservoir will be located on the
port side of the engine between the manifold and the intake diagonally
behind the alternator. The reservoir features a "FULL" marking. This
is not the same as filling the reservoir until it is completely full. The
reservoir requires expansion room while in operation; therefore, the
FULL marking is slightly lower than the top of the tank.
should be done prior to starting the engine. During operation,
pressure builds up in the reservoir. Opening it before the
cooling system has had time for pressure relief likely will
result in an eruption of fluid. It will also be sufficiently hot to
seriously burn skin. Always allow sufficient time for the fluid
to cool and return to pre-operation levels.
It may be necessary to periodically add coolant as a small
amount of evaporation occurs naturally. When adding coolant, use
only a 5-year, extended warranty antifreeze (propylene glycol),
either a premixed 50/50 mix or create a mix of 50 percent extended-
warranty antifreeze plus 50 percent distilled water. (Do not use tap
or other water as other elements in the water can cause build-ups
