My late model outboard has a Flushport on the engine. Why should I purchase a Guardian?
Flushports access the outboard cooling system via one port of entry only. Its effectiveness is limited in several ways. The single point of entry method attempts to force water in several directions resulting in parts of the system getting very little water. With the water entering at the midsection 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 thermostat on engines with flushports 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 flushport engine flushing system regularly and still encounter salt corrosion buildup. The Guardian System forces water under pressure into every cavity of the cooling sy
