The Ultimate Weapon Against Saltwater Corrosion


Now the same technology used by the elite U.S. Army Rangers and U.S. Navy Seals is available to protect your marine engine.

Our patented turbine driven valve converts normal city water into high pressure pulses that blast the salt out of your engine.

Conventional Flushing

If you flush your inboard or sterndrive with earmuffs or factory connections, your exhaust risers might look like the exhaust riser below.  

This particular riser was flushed with earmuffs and had 243 hours on it when it failed.

 This incident resulted in engine failure which cost the owner in excess of $8,000.00.

Super Flushing

If you flush your inboard or sterndrive with SuperFlush your exhaust risers probably look like the exhaust riser below.

U.S. Navy tests and evaluations prove that our Pulsed High Pressure Technology can double or triple the life of marine engine parts exposed to seawater.  

Not to mention increased reliability and safety.

SF 400 Series Marine Engine Flushing System is Easy and Effective


Step 1: Attach hose and turn on water.


Step 2: Engine fills and flushes.


Step 3: Finished in 4 minutes.

The system is the most convenient and effective marine engine flushing and corrosion control system ever made.  Its EASY to install, its EASY to use.  Its operation is fully automatic.  Hook up a garden hose to the installed SuperFlush access panel, turn on the faucet and in four minutes your engine is flushed.  It works with your boat in or out of the water without running the engine!  Nothing works like a SuperFlush.

Why Do I Need  a SuperFlush?

· Salt water caused corrosion damage** is responsible for as much as 70% of marine engine failures.

· SuperFlush* will extend the life of your engines and reduce breakdowns caused by corrosion.

· Works with you boat in the water (or out) WITHOUT running the engines!

· Environmentally and wallet friendly, since you don’t run the engine you don’t pollute or burn expensive fuel!

· Winterize your engine with your boat in or out of the water in just 4 minutes!

· Convenient!

· Safe!

· Great for boats on lifts, davits, or docked!

If you think your closed cooled marine engine is safe from salt and corrosion damage…think again!

The fact is, your manifolds, exhaust risers, primary and secondary heat exchangers, as well as the fuel and transmission coolers and the pump systems (all shown in RED) are unprotected.

Failure of any of these parts will leave you stranded and may destroy your engine.  The system can double or triple the life expectancy and the reliability of your marine engine and significantly reduce the maintenance related costs of ownership. This high technology system can increase cooling system maintenance intervals by years, saving you thousands of dollars in maintenance costs!
