FREQUENTLY ASKED QUESTIONS

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.
