My late model outboard has a Flush port on the engine. Why should I purchase a SuperFlush?
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 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 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 Superflush pressurizes water into every cavity of the cooling system and shock
