I have twin Horizon 5.7's FWC Ser#OL677287 with factory fresh water flush kits installed. My first thought was that obviously you close the seacock and hook up the hose and run the engines for a while and flush out the manifolds and risers. However, I rebuilt the raw water pumps this weekend and I notice that the flush kit is installed in the line AFTER the pump on it's way to the oil cooler. So that lead me to wonder what happens to the pump impellor as it is spinning with no fresh water coming to it, as the fresh water is injected just after it. Will the pump impellers be damaged?
Just wondering about this, as it would seem that the fresh water flush would be cut into the line BEFORE the pump.
In any event, what is the correct procedure to use the factory fresh water flush kits?
Thanks in advance!
