I am losing drive fluid from a Merc #5. The drive is not overfilled. The leak isn't from an obvious location or I wouldn't be writing this post. It does appear to be coming from the vent tube. I only think this because there is some oil high on that side of the transom. The other side seems fine. The amount of fluid loss is about 6 ounces. It always looks worse because of a little water in the bilge making the oil volume look greater. Any ideas or has anyone else experienced this? Thanks!!!!

Don't know about number 5's, but with b-1 reservoir they will leak under way if the o-ring inside cap is missing or if the cap is cracked as there is some pressure present.
