Hi all new to this great forum, Have a question about my evinrude 25 horse 1980 pretty sure, There seems to be a small drain or weep hole on the bottom end just to the left of the top fill screw for the lower end oil. What is that small drain,or hole for? thanx fishforit

The small holes that you may see in various locations in any lower unit are drain holes.<br /><br />In areas of the world where freezing temperatures exist, if not for those drain holes, the water would be trapped. The water would then of course freeze and expand which would crack and destroy the lower unit gearcase.
