? My late model outboard has a Flush port  on the engine.  Why should I purchase a Guardian?

Flush ports access the outboard cooling system via one port of entry only.  It’s effectiveness is limited in several ways.  Because of the single point of entry it attempts to force water in several directions resulting in parts of the system getting very little water.  With the water entering at the mid-section of the engine an air bubble is formed in the upper portions of the cooling system.  No water reaches this area with the flushport.  The thermostats on engines with flush ports are designed to limit water flow and this results in poorly flushed engines.  It is critical that the heads, water jacket covers and all gasket interface areas receive adequate water volume when flushing.  Conversely, with the Guardian’s pulsating action and multi-port entry, the entire cooling system and cooling subsystems are flushed.  You can utilize the flush port engine flushing system regularly and still encounter salt corrosion buildup.  The Guardian pressurizes water into every cavity of the cooling system and shocks the salt and mineral build up out with a hydrostatic pulse, and is a far superior technology.  Additionally the Chemical Products line is a key element in  engine longevity.  Periodic use can greatly extend an engine’s life cycle and greatly reduce maintenance requirements.  In addition, accessibility can pose a problem with the Flush port system when attempting to flush the engine while on the water or on a lift.  Guardian solves both of these problems.

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

Yes!  The Guardian  not only operates with the engines off but flushes in or out of the water. The less efficient alternatives to Guardian 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 flush ports 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 Guardian  help solve this problem? 

Install the Guardian 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 Guardian under nearly inaccessible situations.

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

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

? What about so called T-fittings?  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 Guardian systems overcome these obstacles  by using a multi-point injection scenario, precise metering control and superior technology.

? How can Guardian save Time And Money?

Every major engine manufacturer recommends that you flush  your engine after every use.  If you use a conventional method (Earmuffs, Flush ports, 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.

 Guardian saves you time and money by:

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 Guardian 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 Guardian System.

MONEY:  The Guardian 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.

ENVIRONMENTALLY FRIENDLY:  The Guardian Systems use 80 % less water to flush an engine than any conventional method, saving your money while helping to protect the environment.
