SuperFlush technology uses a scientifically sophisticated yet practical feedback
responsive control and metering system to flush salt and minerals from the
internal components of marine engines more effectively and conveniently than any
conventional method. The system uses an extremely effective multi-point
injection strategy, and a technology known as “ DYNAMIC
HYDROSTATIC PULSE AMPLIFICATION ” to achieve incomparable results in a
convenient and user-friendly environment, which through ease of use will
engines which are raw or seawater cooled, the unit receives water through a
quick disconnect fitting on a regular garden hose and enters the engine on each
side of the thermostat(s) through fittings installed on the engine replacing
plugs that are already in the engine or by tapping into hoses normally
installed on the engines.
On engines, which are equipped with a closed cooling
system, the system is configured to effectively flush the components that are
most at risk from the damaging combination of sea water and heat. Heat
increases the causticity of seawater by a factor or 3 at 160 degrees Fahrenheit
and adds to the buildup of potassium, magnesium and sodium residues inside the
engine cooling subsystems.
maximize the benefits of the SuperFlush* System the engine is not run during
flushing as research indicates this to be counter productive. On some
engines conventional flushing may actually do more harm than good. Due to the
limited volume of available water and the high capacity of the modern marine
engine pumping systems, engine cavity and exhaust components are not completely
filling with water, leaving upper reaches of these subsystems dry, and with
much higher than normal temperatures.
casting marks, seams, transitional areas of uneven thickness and any 90 degree
or greater bend in the coolant flow channels in modern marine engines of all
types are all natural attractors for salt build-up, which seems to proceed in a
roughly geometrical progression once started.
salt build-up occurs, it effectively creates an isolation boundary layer that
blocks the dissipation or radiation of heat. When this happens, hot spots occur
which cause thermal stress and/or shock
- which rapidly lead to failure.
It was also determined that up to 90% of impeller wear (on systems using
centrifugal style neoprene based impellers) occurred during engine flushing.
Not surprising, considering the pump requirements vs. the available supply, the
SuperFlush System overcomes these problems and others with a combination of
- The engine is not run
with the SuperFlush System, so no heat is generated to create hot spots.
- The metering components
of the SuperFlush System constantly adjusts the output levels of all
injection points, insuring continuous pressure and volume levels in all
the engine subsystems (water transfer systems, heat exchange systems, raw
water pumps, circulating pumps, engine block and heads, and manifold

subsystems at between 7000 – 10,000 times per minute, depending upon the
