I Know this sounds nuts but for the life of me I can't figure out where the water intake is on a 1976 Evinrude 25hp wth electric start. I have been flushing this motor in a barrel, but would like to have the option of using muffs from time to time. I have looked over the whole thing and have seen holes but can't make out which one is the intake. I'm assuming that the plate with the three slots is some kind of water bypass? Ah who knows, I nee help from someone who knows. Thanks in advance for any advice you cangive me,<br /><br />Ron
