Well I noticed oil had run down the bottom of the motor. I took cover off motor and it looks like it has leaked out the bottom of a flat cover that is between the cylinders. (sorry I don't know what this cover is called)The motor is a 1989 v6 XP150 Evenrude. The oil looks old. I did not see this problem until I left the motor down because of cold weather. I took it to the river today and it ran fine. Do you think this is a problem or is this normal??
