1.
Why should I use the PWC ProFlush system to flush and winterize my
watercraft?
The PWC ProFlush system provides a quick and easy way to flush and
winterize your personal watercraft with professional results. The
patent-pending PWC ProFlush system delivers a precisely measured and
pressurized pre-mixed flushing solution or marine grade anti-freeze
to your watercraft's cooling systems. The PWC ProFlush system is
self-contained and doesn't require a water hose or complicated
mixing and distribution devices. With the PWC ProFlush system you
can flush or winterize your watercraft at the boat ramp, on a
trailer, or in your driveway - in about 60 seconds!
2.
How does the PWC ProFlush system work?
The PWC ProFlush system includes a holding tank that is manually
pressurized via a pump assembly; an attached translucent heavy duty
coil hose with a brass end fitting; a pressure regulator; a high
quality on-off valve, and a hose pincher. Assembly is quick and easy
and once assembled, you simply add 1 gallon of water mixed with 2
oz. of our flush solution concentrate, or 1 gallon of marine grade
biodegradable anti-freeze; pressurize the tank; connect the coil
hose to your watercraft's flush kit connection; start the motor;
open the on-off valve; and monitor the flow of flushing solution
through your engine cooling and exhaust system.
3.
Why is it necessary to flush your PWC engine and cooling system
after every use?
PWC motors are high performance gas combustion engines that generate
a lot of heat. To dissipate that heat engine manufacturers use
several different types of cooling systems including a direct sea
water system and a fresh water closed loop system. Both
systems provide a flow of cooling liquid to the engine and exhaust
components. These cooling system components are made of aluminum or
cast iron and are highly susceptible to internal corrosion from the
salt and other contaminants found in sea water. Sea water left in
these cooling system components and passages will begin to corrode
metal cooling components very quickly, weakening the metal, causing
pitting, obstructing the smooth flow of cooling water and eventually
causing a cooling system failure and serious engine damage.
4.
Is is necessary to flush "closed loop" cooling systems
that circulate an anti-freeze solution instead of sea water?
Yes, although closed loop systems keep the sea water out of the
engine cooling system, sea water is still used in a heat exchanger
to transfer heat from the engine cooling solution. Sea water is also
used in many closed loop systems to cool exhaust components. There
are many metal components in a fresh water closed loop system that
require flushing to prevent corrosion and insure a long service
life. Without proper flushing and winterization, sea water trapped
in these components or passage ways will cause corrosion and can
freeze, causing extensive and expensive cooling system and engine
damage.
5. Is
it necessary to winterize using a marine grade biodegradable
anti-freeze before winter storage even if my owner's manual doesn't
require it?
If your watercraft could experience any below freezing
temperatures during winter storage you need to flush your engine and
cooling system with a marine grade biodegradable anti-freeze prior
to winter storage. Although many manufacturers claim their systems
are "self draining" and do not require winterization, why
take the chance? Any trapped water in the cooling system or passage
ways, including the engine, heat exchanger, exhaust system and water
box, will freeze, expand and cause extensive and expensive damage.
With the PWC ProFlush system, your last flush of the season can be
done with a gallon of marine grade anti-freeze treated with our
flush fluid concentrate for complete protection from freezing and
corrosion during the long winter storage period.
6.
Why can't I use an ordinary garden sprayer to flush my PWC?
Although parts of the PWC ProFlush system resemble a standard garden
sprayer there are significant design and construction differences
that make using an ordinary garden sprayer ineffective and possibly
hazardous to your PWC. First, our tank and pump system are
constructed to safely create and maintain the relatively high
pressure required to effectively distribute 1 gallon of flushing
fluid through your PWC's engine and cooling system. To prevent over
pressurization of the tank, a safety release system is built-in to
insure any excess pressure is released before it can cause harm or
damage to the system. Our pressure pump is manufactured with a
quality metal pump shaft and stronger, tighter sealing gaskets to
insure many years of trouble free operation. Ordinary garden
sprayers simply cannot create and hold the necessary pressures
required of the PWC ProFlush System.
In addition, the PWC ProFlush system uses a larger diameter output
hose (with a standard male hose end fitting) as well as a larger
diameter pick-up tube inside the tank to insure the necessary volume
and flow of fluid reaches your PWC. Ordinary garden sprayers use
much narrower output and pick-up tubing that would result in not
enough fluid reaching your PWC engine and cooling system and
possibly causing an overheat situation that could severely damage
engine and cooling system components.
Finally, the PWC ProFlush system includes a pressure regulator and
quality shut-off valve to insure an even and consistent flow of
fluid to your PWC. Without such a regulator, the sudden release of
pressure could cause damage to the narrow tubes and plastic fittings
used in the PWC cooling system. Why take a chance and risk serious
engine damage. The patent-pending PWC ProFlush system is designed,
tested and manufactured specifically for the purpose of flushing
your PWC engine.
