1974 40hp Evinrude .Bought and installed the new impeller kit . Cleaned out and used compressed air to clean any old parts . Installed new impeller kit and put lower end in water . Started engine , no water pumping thru engine . Remove the head and blowed air in all areas I found . Put back together again no water pumping the the engine . I have not put boat in the lake as of yet . I am very confused . I am not impressed with the new style impeller kit .
