Grease w/water draining 7.5 merc

[donlee]

HELP I have water mixed with lower unit grease draining from tiny pin hole on top side of of propeller shaft housing. Is this a vent hole, I have not seen it before. How is grease getting mixed with water? mattsdr@cybrzn.com

Well it could be a vent that exhaust residue mixed with water is coming out. To be sure, check your lower unit fluid level, and see if it has water in it. If it does, or it is low, that will answer your question.

Thank you Nathan, but can you tell me how water would get into the lower unit grease chamber. Also can you tell me where the cooling water would drain from when you pull the motor out of the water. This is a 1971 7.5 HP.
