Superflush Advantages

How much does it Cost?

Superflush kits start at $249.00.  The most common kit is $299.00.  ABS Marine can install the engine flusher for you, or give you advice so you can do it yourself.  Installation starts at $99.00 per engine. 

Why aren't the old fashioned ear muff style flushing devices adequate for flushing my engine?

The ear muff flushing devices are Thirty year old technology and they have critical shortcomings. Marine engines utilize high volume water pumps, mostly with neoprene rubber impellers. Any interruption in the water flow while the engine is running will severely damage the impeller. With the ear muff device, you are simply not getting the volume of water into the water pump and in many instances it will cause the garden hose to collapse.

Overheating is extremely detrimental to engine life and in severe instances may result in immediate damage. In fact, some marine engine repair manuals contain the following statement:


At 1500 RPM the engine water pump can only create approximately five pounds of pressure in the cooling system. This is not nearly enough volume of water to flush the engine properly. It has little or no effect on the salt corrosion buildup inside the engine block. Conversely the SuperFlush System back-fills the idle engine, pressurized the cooling system to twenty two pounds and pulsates the water to shake the salt corrosion out of the engine.


My boat stays in the water almost all the time. Will SuperFlush allow me to flush my engine without pulling the boat out of the water?

Yes! The system not only operates with the engines off but flushes in or out of the water.

The less efficient alternatives to are to install an expensive custom flushing system with brass piping and gate valves on your inboard, purchase an outboard with flushports or use earmuffs on your engine. The flushports and earmuffs still require that you get in the water to utilize them.

My boat is on a lift and virtually impossible to access with conventional flushing devices. How can SuperFlush help solve this problem?

Install the hose connection access panel on the side of your boat. By utilizing a commercial grade quick connect fitting on your garden hose, you can snap the hose on and by simply turn on a valve connected to the end of the garden hose to activate your flushing system. With this setup you can utilize the under nearly inaccessible situations.

I would like to install SuperFlush on my new boat but I'm concerned about the engine warranty. Will SuperFlush affect my warranty?

Your warranty stays intact. The SF is a completely passive system. Your engine warranty is not affected.

My engine is already fresh water cooled. Do I even need to worry about corrosion?

Even freshwater or closed cooling systems have components which are exposed to salt water corrosion.
They are:

  • The Pumps
  • The transfer system
  • The heat exchangers
  • Oil & Transmission Coolers
  • The exhaust risers and
  • In most cases, the exhaust manifolds

The system solves these problems by flushing all of these components. Additionally it can save you thousands of dollars in maintenance costs. How? Using the environmentally safe chemical treatment programs means that routine (until now) heat exchanger service and replacement is NO LONGER NECESSARY.

Can the SuperFlush System be used to winterize my engine or flush other chemicals through the system?

Yes! We offers a full line of chemical treatments including an anti-marine growth solution for retarding zebra mussels and other fouling marine growth. They also offer anti-corrosive treatment and anti-freeze treatments. All of these are available through your dealer. Chemical induction kits make quick and easy work of engine lay up or winterization procedures.

Also, flushing the engine periodically with FlushClear offers an additional anti-corrosive protection and lubrication of the cooling system components.

If my boat is out of the water and I need to start my engine for test purposes, can I access my system to provide water for the cooling system?

We recommend the engine's be off when utilizing the system. However, in this instance you could use the system as long as you do not exceed 1100 RPM. Higher RPMs can result in damage to the water pump. Remember, the system flushes from the top down and the water pump is pushing the water up into the engine. In this instance, they are working against each other. That is why we do not recommend running the engine while utilizing the system.

What about so called T-fittings or hose connections? Why don't they do the job?

T-fittings access the engine at one point only, either upstream or downstream of the raw water pump. Either junction is inadequate because of the limited water flow available from the municipal water supply. If the T-fitting is downstream of the pump, over 65% of the available water supply will run out the water pickups and be unavailable for engine flushing. If the T-fitting is installed upstream of the raw water pump, then the engine will fill to the first gravity drain point and no further because of inadequate volume. The circulation through the engine will be minimal, and the upper reaches of the exhaust systems will not be cooled or flushed. Additionally over 90 % of impeller damage and wear occurs while attempting to flush engines, caused by impeller cavitations in the centrifugal housing. The systems overcome these obstacles by using a multi-point injection scenario, precise metering control and superior technology.

How can SuperFlush save Time And Money?

Every major engine manufacturer recommends that you flush your engine after every use. If you use a conventional method (Earmuffs, Flushports, or T-fittings), you should run the engine from 18-22 minutes at a high idle to ensure that the thermostats open. This makes your engine run at higher than normal exhaust temperatures, resulting in premature engine wear and shortened engine life. And it's time consuming, noisy, expensive and environmentally unsound.

SuperFlush saves you time and money in the following ways :

  • MONEY: You don't run the engine. So you don't use fuel. Using other methods require 18-22 minutes of running time. At $1.50 per gallon (avg. cost of fuel purchased at marina) based on 6 g.p.h. (gallons per hour) consumption at idle of a 5.7 Liter inboard, that's $3.12 of fuel per flush. At 100 flushes that's $312.00.
  • TIME: The System is fully automatic. Connect the hose, wait four minutes and you're through. Other methods require 18-22 minutes of supervised flushing. At 100 Flushes you've wasted 30-36 man-hours flushing your engine Vs. 6 hours 40 minutes for the SuperFlush System.
  • MONEY: The System's superior performance will greatly increase the operational life cycle of your marine engine by reducing corrosion related problems. By far the number one cause of engine failure.
  • MONEY: Less corrosion damage means less money spent on maintenance and parts.
  • MONEY: The Systems use 80 % less water to flush an engine than any conventional method, saving your money while helping to protect the environment.

Recreational craft engines come in two broad categories - outboard or inboard. These different engine types have markedly different emissions characteristics as outlined below.

Outboard engines are usually mounted at the rear of the vessel and have a self-contained drive unit. The small size, weight and low purchase price make outboard engines popular for smaller craft. Most outboard engines are two stroke gasoline units using an oil/gas mix although four stroke outboards are growing in popularity and the use of propane gas for both 4 and 2 stroke engines is also becoming more popular.

As the name suggests, inboard engines are mounted inside the craft and drive is relayed through various different transmission systems such as shaft drive/propeller, stern drive/propeller, sail drive and water jet drive. The latter are used on personal watercraft.

Inboard engines tend to be used within larger craft and are usually fuelled by gasoline or diesel. These engines are generally more powerful and are used where the weight and size of the unit are not the overriding consideration. Many inboard engines are marine derivatives of commercial automotive engines. Although diesel inboard engines are becoming increasingly popular, four stroke gas engines are usually chosen where installation space is more limited or where higher power to weight ratios are required, as with water sports craft.

Is SuperFlush environmentaly friendly?

During the combustion process, internal combustion engines of all types generally produce, in varying quantities, the following substances:

  • 4 stroke engines generally produce higher CO, CO2, and NOx, but lower HC than 2 stroke engines. 2 stroke engines emit relatively high levels of HC in both burnt and unburned form, but low levels of NOx. Diesel engines are more fuel efficient than 4 stroke or 2 stroke petrol engines and therefore emit lower overall CO and CO2 However, they produce greater quantities of SO2, Nitrogen Dioxide and particulates. In terms of marine features, it is the effect of hydrocarbons and lead in the water column and sediment that are of key significance.
  • Nonpoint Source Pollutions are caused when marine engines of any kind are flushed WITH CONVENTIONAL TECHNOLOGIES in proximity to any inland waterway, intercostal waterway, or tributary which leads into any navigable waterway or water system. It is expressly prohibited by the Code of Federal Regulations under the Federal Rainwater runoff act of 1997.
  • Hydrocarbons - modern outboard, inboard and stern drive engines exhaust below the water surface and, as a result, all hydrocarbon emissions pass through the water. Except when they are being "flushed". Flushing is a process where the engine is ran while connected to a water supply. The intent is to remove the corrosive salt water from the engine and drive elements. Traditional engine flushing is an environmental disaster. Elevated exhaust emissions and emulsions from the contaminated effluent goes directly into the atmosphere and into the ground water reservoir, or runs back into inland or coastal waterways and is a serious source of both air and water pollution. Engine flushing using traditional methods is directly responsible for introducing millions of tons of NOx, CO,CO2,HC,SO2, lead and particulate matter into both the air and the ground water reservoir. With over 19 million boats in the U.S. alone, it's easy to see the size of the problem.

The Superflush system is the answer.

  • Zero emissions
  • Zero Emulsions
  • No Noise and No Pollution from the best and most convenient marine engine flushing and corrosion control system in the world. It's the right choice for responsible boaters.
